Acknowledgments

This thesis is the final challenge that I took up in order to finish my master Human Resource

Management. The moment I am writing this preface makes me look back on the last months,

and on the process that led me to reach my final goal. Finishing this assignment means that I

will no longer be a student at the Erasmus University. The end of my student life also implies

a new starting point with many new challenges ahead. I was able to finish my thesis in only a

few months' time and therefore I would like to thank especially some of my colleagues and

friends who have been supportive.

First of all I would like to thank the Erasmus@work research group for enabling me to

join the New World of Work Research project. Being part of this group increased my

enthusiasm and determination to write my thesis. I owe many thanks to my coach, Dr.

Michaela Schippers ,who stood by me at critical moments during the process of writing my

thesis. I would also like to thank my co-reader Dr. Van Baalen, who reviewed my thesis in a

critical way, while thinking along with me. Writing my master thesis would not have been

possible without the cooperation of Rabobank, I would therefore like to thank the employees

who filled out the questionnaire.

Finally, I would like to thank my family and friends. From the moment of choosing a

topic until the moment I handed in my thesis, they always supported me. Their everlasting

trust encouraged me to persevere and made me believe that this challenge was not impossible

for me.

Executive Summary

Empowerment can be of great value for a company and its employees. However, to be able to

benefit most from giving employees empowerment, it is not only important to focus on the

achievements that could be gained by giving employees empowerment, but also to take into

account the possible disadvantages and risks. This study investigates the relations between the

dimensions of empowerment (impact, competence, meaning and self-determination) and

affective commitment. This study also investigates the interactional effects of the dimensions

of empowerment with job engagement and trust in the management on affective commitment.

The research was done among Dutch employees working at the Rabobank. Rabobank

has an internal program which is focused on giving employees more responsibilities and more

autonomy in their work. This program has been implemented gradually, and employees who

were just acquainted with the program have been approached for this study.

The results of this study show two main effects, the first main effect is a marginally

significant one with empowerment meaning and the second one is a significant inverted u-

shaped relationship. Besides significant moderating effects are shown. The results show that

empowerment meaning is positively related to affective commitment. Thus, when an

employee feels his work is meaningful and fits in with his personal ideals, it positively relates

to affective commitment. An inverted u-shaped relation is found between self-determination

and affective commitment. This means that an increase from low to moderate levels of self-

determination is associated with an increase in affective commitment. However, affective

commitment decreases at relatively high levels of self-determination.

In addition to these effects, there are also certain moderating effects. The results show

that job engagement can strengthen or weaken the relationship between empowerment

competence and affective commitment. The highest degree of affective commitment can be

achieved by a low level of competence and a high level of job engagement. The results also

show moderating effects with trust in the management and three dimensions of

empowerment: impact, meaning and competence. When an employee scores low on

empowerment meaning, the degree of identification with organizational goals, and scores high

on trust in the management, this leads to the highest degree of affective commitment. When

the employee has already identified his own goals with those of the organization, trust in the

management does not play a large role. The second interaction to achieve the highest degree

of affective commitment, shows the employee has to feel he has an impact on the

organizational outcome and trusts the management. Finally, a low score on an employee‟s

iv

competence in combination with a high score on trust in the management causes the highest

score on affective commitment. For these latter two interactions with the dimensions impact

and competence, the degree of trust in the management is especially important when the

employee already has a high score on these dimensions.

Empowering people does not automatically cause benefits for the organization. It is

important to take into account the degree in which employees are empowered, as well as the

role of job engagement and trust in the management.

1. Introduction

Imagine, you have a full-time „nine to five‟ job and the office is one hour by car from your

house. Taking the traffic into account, you depart at half past seven in the morning. When you

are lucky, your working day ends at five o‟ clock, but usually the meeting takes longer and

you will not make it on time for dinner. During your car drive you think about the day at the

office and realize you did a great job for the boss, you finished all the tasks your manager

specified for you. However, if you look closer it was a great job for your boss, but are you

really satisfied by performing precisely what your boss wanted you to do? This is not why

you did four years of study! Fortunately, your lovely spouse already heated up your food and

you are exactly on time to watch the evening news. Unfortunately, the children are sleeping

already as it is almost every time on a midweek day. After a while, you get used to it, but this

is obviously not an ideal situation.

Now imagine the situation from a different point of view. You are the manager of an

organization, having a lot of deadlines, impossible to achieve all by yourself. What„s more,

you have the feeling that the expectations of your employees are changing; they seem to want

to solve problems by themselves and do not want to be told in detail what to do day after day.

Sometimes you secretly think of a way to delegate decision making by giving your employees

in the organization some of your responsibilities. But how do you know for sure that they can

manage these responsibilities? Giving employees autonomy in their jobs, but still telling them

how to perform the task in detail and controlling their behavior, does not make a lot of sense.

In the last few decades, a lot has changed for organizations, leadership and employees. In this

rapidly changing environment, in which globalizing organizations have to deal with a lot of

competition, and which is characterized by immense developments in technology, by

employees who attach great importance to self-employment and self-determination and by

organizations‟ processes and rules that are no longer top-down, there is a need for research.

In contemporary economy, concepts like autonomy, empowerment, knowledge

workers, commitment and job engagement are widely used to improve performance in several

ways. Companies and in scientific literature show great differences in their approach to

organization management. There are different kinds of organizations varying for example in

products, in technology facilities, size, workforce and purpose which requires a unique

approach. And even organizations which are very similar to each other may well show a lot of

differences in, for example the delegation of power.

2

Our economy has changed from an industrial economy into a knowledge economy

(Drucker, 1993). During this period a lot has changed, the focus has shifted away from the

manual worker to the knowledge worker. In his book „The future of work‟, Malone (2004)

states that we are in a revolution. In the past it was accepted that people could exercise power

over others in society, and this was also common practice within companies. In the current

revolution mentioned by Malone, personal desires are more important. For example the

knowledge workers attach great importance to personal desires like flexibility, freedom,

creativity and motivation. According to Davenport (2005) knowledge workers are

characterized by their need for a certain degree of autonomy in their work and their

unwillingness to share knowledge. This is because their knowledge can be seen as a

competitive advantage, something that makes a knowledge worker special and valuable for

the organization, which the employee would want to protect. However his unwillingness to

share knowledge also can be caused by a lack of trust. In both cases this leads to a situation in

which employees will not share knowledge in the interest of the organization, but will only

think of their individual interests. The degree in which employees have an energetic and

effective connection with their work activities and see themselves as able to deal completely

with the demands of their job is called engagement (Schaufeli et al, 2002).

In present-day knowledge economy it is important to know how to deal with the needs

and characteristics of the knowledge worker and his degree of job engagement. A concept that

concerns power and preferred autonomy is the concept of empowerment. There is a growing

consensus that employee empowerment can be a source of competitive advantage for

contemporary organizations (Quinn & Spreitzer, 1999). The concept of empowerment may

play an important role in meeting organizations' demands.

One of the outcomes influenced by empowerment is commitment. Commitment refers,

according to Porter et al. (1974), to the strength of an individual's identification with and

involvement in a particular organization. The degree of commitment can positively influence

several organizations‟ outcomes. However, besides this positive image around the concept of

empowerment, is there any chance a company empowers its employees too much? In general,

is there a positive relationship between empowerment and commitment, in which an increase

in empowerment causes an increase in commitment, or is there a chance that this relationship

might change from a certain degree of empowerment? In other words, is there a risk of losing

the employees‟ connection with the company because they are allowed too much

empowerment? Committing the knowledge workers can be of great importance to keep them

focused on the overall goal of the organization so that the knowledge workers will not become

3

too individualistic and to make them more willing to share their knowledge and not behave in

a selfish way, which eventually can lead to better overall performance. Prior research has

already shown that empowerment and commitment are related, but could there be variables

that influence this relationship? For example, what is the role of job engagement in this

relationship or the role of trust?

The aim of this thesis is to gain a clear insight into the relation between employees‟

involvement and their identification with the organization, and empowerment to knowledge

workers, taking into account the new (flexible) working environment with its rapidly

changing technologies. In specific, the focus will be on affective commitment, in the sense of

the employee who prefers to stay within the organization. Affective commitment is related to

several beneficial behaviors. As already mentioned it is important to keep the knowledge

worker focused on the overall goal of the organization and besides it is important to keep the

knowledge worker within the organization in order to keep the knowledge. Besides, the

effects of job engagement and trust in the management in this relationship will be examined.

The following research question has been formulated:

How does empowerment influence the employee‟s affective commitment to the organization

and what is the role of job engagement and trust in management in this relationship?

In this thesis first the literature will be discussed related to the study. In addition the

hypotheses are specified. In the third chapter the relevance, the research goal and contribution

are defined. In the fourth chapter the research model and a summary of the hypotheses are

presented. How the model is tested is specified in chapter 5. In chapter 6 the results found in

this research are presented. These main findings and results serve as a basis for a conclusion

and for future research.

2. Literature

2.1 Current environment

During the transition phase of the industrial economy to the knowledge economy, a lot has

changed. The focus has shifted away from the manual worker to the knowledge worker.

Today‟s society is characterized by individualization and quite some development in

information technology. In the past, people lived in communities. Within these communities

people shared beliefs, standards and values. Gradually this changed and people became more

detached of these communities and consequently more aware of their own interests and

desires. Besides, they became more independent in structuring their life. This trend can be

seen in business life as well, in a way that people are more demanding and attach more value

to freedom, flexibility and creativity (Malone 2004). Besides this change in society,

information technology has developed immensely. This has led to lower communication

costs, has ensured fading boundaries and has made the world smaller and larger

simultaneously. As to knowledge sharing, these developments make the world smaller,

because distance no longer plays an important role, and larger because more knowledge is

available. Increased opportunities to share knowledge have also influenced business life.

When information sharing is easier, organizations can operate outside their boundaries.

Within organizations information technology plays an important role as well. The revolution

in business life dealing with power and control mentioned by Malone (2004) is possible

because of information technology development. Employees or knowledge workers have the

possibility to share more information in a shorter period of time. Drucker (1993) mentioned

the need to pay more attention to knowledge work and knowledge workers influenced by the

development of information technology. He also emphasized that the most important

contribution of management in the 20th

century was the immense fifty-fold increase of the

productivity of the manual worker. In the 21st century the most important contribution needs

to be a similar increase in productivity of the knowledge worker.

2.2 Knowledge workers

In his book „Thinking for a living‟, Davenport (2005) defines knowledge workers as follows:

“Knowledge workers have high degrees of expertise, education, or experience, and the

primary focus of their jobs involves the creation, distribution, or application of knowledge”

(p.10).

5

This definition still does not make clear the exact characteristics of a knowledge

worker and how can be determined if an organization has to do with them. According to

Davenport (2005) a knowledge worker can be characterized by six characteristics, listed and

summarized underneath.

1. Knowledge workers like autonomy: Knowledge workers are hired for their

knowledge and are paid for their expertise, experience and education. As a result, they can be

offensive when someone else interferes in his or her area of expertise. However, the

knowledge worker does not want his work to be ignored by others and wants to be informed

about the broader significance of his task. A certain degree of autonomy is preferred.

2. Specifying the detailed steps and flow of knowledge-intensive processes is less

valuable and more difficult than of other types of work: In the first place it is not very useful

to analyze process workflows of a knowledge worker, because another knowledge worker

could perform the same task in a different way. Moreover, it could be very complex in some

cases. Sometimes it is impossible to describe the workflow when the number of variations is

too great.

3. You can observe a lot by watching: It is very hard to describe the working processes

of a knowledge worker, therefore the technique of observation is often used to get a better

insight in the process.

4. Knowledge workers often have good reasons for doing what they do: one needs to

take the workers at their word or deed. Knowledge workers have a certain way of working

and have their reasons for acting like they do.

5. Commitment matters: It is inconceivable for the knowledge worker to achieve a

great performance when he or she is not mentally and emotionally committed to the job. As

noted earlier, the knowledge worker prefers a certain degree of autonomy. A perception of

fairness and giving the knowledge worker a say can foster his commitment.

6. Knowledge workers value their knowledge, and don’t share it easily: To a

knowledge worker, knowledge is his competitive advantage, as something very valuable and

distinctive. Knowing this, a knowledge worker is probably not willing to just share his

knowledge.

In short, managing knowledge workers with the aim of excellent performance,

demands a deliberate approach. Taken into account the preferred autonomy and the required

commitment to the job, attempts should be made to keep the knowledge worker within the

organization. Besides, the unclear work processes and thereby the need for trust in the

6

employee possibly calls for changes in leadership style. Finally, one needs to deal with the

unwillingness of the knowledge worker to share knowledge.

2.3 Empowerment

In his book „The Future of Work‟ Malone (2004) describes the current revolution in business

which involves power and control. There are several ways to deal with power and control in

an organization and it is important to take into account the present environment. In his book,

Malone states that because of the importance of knowledge workers and development in

information technology, decentralization in organizations can be expected. Malone defines

decentralization as “participation of people in making the decisions that matter to them”(P. 5).

The concept of decentralization described by Malone is close to another concept that deals

with power and control, empowerment. According to Liden & Tewksbury (1995)

empowerment is an important construct because it offers the potential to positively influence

outcomes that benefit both individuals and organizations. Besides Quinn and Spreitzer (1999)

mention that there is a growing consensus that employee empowerment can be a source of

competitive advantage for contemporary organizations. The concept of empowerment is

defined in a variety of ways, by a number of researchers.

According to Rodwell‟s analysis (1996) the concept is widely used in society for

several ideologies. In this analysis she describes that the concept of empowerment would

appear to be a process of enabling or imparting power transfer from one individual or group to

another. This means for example that someone gets the right to make a decision while this

right previously belonged to someone else. Spreitzer and Doneson (2005) define the concept

with a focus on employees, and deepen the definition of Rodwell (1996) by stating that

empowering practices allow employees to decide on their own how they will deal with a

problem.

Aside from different definitions of empowerment, the concept is also in several ways

divided in literature. Quinn and Spreitzer (1999) discovered two very different perspectives of

empowerment during interviews in an organization that had started an empowerment

program. The researchers advocate two approaches, a mechanistic approach, referring to a top

down process in which empowerment is about delegating decision making within a set of

boundaries, and an organic approach implying a bottom up process in which empowerment is

seen as a process of risk taking and personal growth.

7

Spreitzer and Doneson (2005) review three perspectives used by contemporary

management scholars and practitioners to understand empowerment. First, the social

structural perspective emphasizes the importance of shifting away from organizational

policies and structures that foster powerlessness, toward high involvement practices. Second,

the psychological perspective refers to a set of psychological conditions necessary for

individuals to feel in control of their own destiny and third, the critical perspective argues that

feeling empowered is not the same as being empowered. Taking into account these different

perspectives, empowering people partly appears to be about implementation and facilitating

people and partly about awareness and allowing people time to get used to it. Saying to people

they are empowered, is also not the same as feeling empowered.

In their focus on the psychological perspective of empowerment, which takes into

account the internal processes of the employee, Thomas and Velthouse (1990) mention four

dimensions. Individuals make judgments with respect to various tasks and use them to

interpret their working situation. The four dimensions mentioned by Thomas and Velthouse

are meaning, competence, self-determination and impact. Meaning is the dimension in which

the individual assesses his working activities as meaningful, depending on the degree of fit

between work role or goals and personal beliefs, values and behaviors. Impact is about

making a difference in one's working environment and the extent to which outcomes in work

can be influenced. Competence refers to the belief of one‟s capability to perform work

activities, also called self-efficacy, which is comparable to self-esteem. The dimensions

impact and competence defer in the way that impact focuses on perceived control in the

working environment and competence focuses on control on one‟s work activities (Butts et

al., 2009). Self-determination refers to the sense of autonomy and the degree to which

decisions can be made about how to perform the task. According to Stander and Rothman

(2009) the four dimensions of psychological empowerment create an overall construct of

psychological empowerment. The lack of one of the four dimensions will cause a decrease,

but not completely eliminate the overall effect of experienced empowerment. For example, in

the case that someone cannot identify his own goals with the ones of the organization, he

could feel that he can contribute to the goals and outcomes of the organization to a high

degree. In this way, by splitting empowerment into four dimensions, it is possible to examine

the origin of a sense of empowerment.

Research already showed the influence of empowerment on several outcome variables

and in several environments. In a study conducted among staff nurses, empowerment showed

increased levels in trust, which in turn had a positive influence on affective commitment. This

8

research also showed an increased work effectiveness (Laschinger et al, 1999). Previous

research of Jun et al. (2006) and Spreitzer et al. (1997) showed that empowerment has a

significant influence on job satisfaction. The first research showed results in Maquiladoras in

Mexico, locations for off shoring manufacturing. And the research of Spreitzer et al. showed

results in a manufacturing and a service organization sample.

2.4 Affective commitment

According to Suliman and Iles (2000), organizational performance is determined for a

significant part by the level of organizational commitment. Besides, organizational

commitment affects or is related to other outcomes, like employees‟ absenteeism (Sagie,

1998) and turnover (Somers, 1995). In literature commitment is defined in many ways. Porter

et al. (1974) describe commitment as “the strength of an individual's identification with and

involvement in a particular organization” (p. 604). Building on this definition, following the

article of Allen and Meyer (1990) organization commitment emphasizes the attachment to an

employing organization, including its goals and values and thereby define it as a mindset.

This mindset or psychological state concerns the employee‟s relationship with the

organization. In this article organization commitment is divided in three components;

affective commitment, continuance commitment and normative commitment. First, affective

commitment refers to the “employees‟ emotional attachment to, identification with and

involvement in, the organization” (p.1) or to the “employees' emotional bond to their

organization” (Rhoades et al, 2001, p.825). Secondly, continuance commitment refers to the

recognition of costs when leaving the organization. Kanter (1968, p. 504) defines continuance

commitment as “profit associated with continued participation and a cost associated with

leaving“ and thus the importance and the benefits of remaining within the organization.

According to Meyer and Allen (1990) both components or views cause a decrease in leaving

the organization, but affective commitment is about the employee's wish to be part of the

organization and wants to stay in the organization and continuance commitment is about the

need to stay within the organization. Finally, normative commitment is about the obligation of

staying with the organization from a moral point of view. In their article on lifetime

commitment, Marsh and Manaari (1977) define this to be a sense of moral duty to stay within

the organization, independent of the satisfaction the employee gains by it. Allen and Meyer

(1990) use this definition for explaining normative commitment. In their concept, there is

again a link with turnover, but here it concerns a sense of expectation.

9

The insights mentioned above about commitment are important, because they show in

which ways employees can be committed to the organization. When viewing the meta-

analysis conducted by Meyer et al. (2002), we can draw the overall conclusion that the

strongest correlations exist between affective commitment and the outcome variables. In this

analysis the three components are examined on turnover and withdrawal cognition,

absenteeism, job performance, organizational citizen behavior, and finally stress and work-

family conflict. For all these outcomes the correlation with affective commitment is

considered the strongest. Work behaviors like attendance, job performance and organizational

citizen behavior have the strongest positive relationship with affective commitment, followed

by normative commitment. Continuance commitment is not positively related to these

variables, but is unrelated or negatively related to these behaviors.

Apart from the results of this meta-analysis, other research also showed some positive

relations: Affective commitment is assumed to be positively related to behaviors that are

beneficial to the organization such as performance, attendance, and staying with the

organization (Mathieu & Zajac, 1990; Meyer & Allen, 1997; Mowday, Porter, & Steers,

1982; Randall, 1990).

When viewing the three above mentioned components of commitment, we assume that

empowerment will especially influence the affective component or the normative component

of commitment. The affective component because research already showed a positive relation

between empowerment and affective commitment (Laschinger et al., 1999). Also a

relationship between empowerment and job satisfaction has been demonstrated (Jun et al.,

2006; Spreitzer et al., 1997). Job satisfaction is defined here as the degree to which an

employee is proud of his or her company, and satisfied with the job. A relation between

empowerment and normative commitment can be expected because of a sense of obligation

caused by empowering the employee, for example when he is given more autonomy. A

relation between empowerment and continuance commitment is less obvious, because the

degree of continuance commitment depends on the need to stay in the organization and is

assumed not to be caused by empowerment. It can be very important to „hold‟ people within

the organization, working toward the same goal and achieving a good performance. For this

research there will be a focus on the relation between empowerment and affective

commitment, because of the strongest correlations found with desired outcomes (Meyer et al.,

2002). There will be examined how psychological empowerment is related to affective

commitment.

10

2.5 Relationship between empowerment and affective commitment

Regarding the characteristics and desires of the contemporary knowledge workers, the

concept of empowerment may play an important role by meeting their demands. One of the

outcomes influenced by empowerment is commitment. Previous research of Avolio et al.

(2004) already showed this relationship. In this research also is mentioned that empowered

employees are more willing to reciprocate with higher levels of commitment. In the research a

definition of organization commitment is used from Mowday et al. (1982). In their research

they define the concept as “the relative strength of an identification and involvement in a

particular organization” (1982, p.27). In another research of Laschinger et al. (1999) the

relationship between empowerment and affective commitment, in which trust plays an

important role, has already been shown. Does this relationship still exist in the contemporary

competitive and rapidly changing working environment, in which there is an increase in

knowledge workers?

H1: A relationship is expected between empowerment and affective commitment.

When we split the concept of empowerment up into the four dimensions specified by

Thomas and Velthouse (1990) we expect three relationships to be positive. First, we expect a

positive relationship between empowerment impact and affective commitment. Previous

research has not shown the relationship between impact and affective commitment. However,

Ashforth (1990) argues that fostering a sense of control can stimulate involvement. It may be

assumed that when an employee feels that he really contributes to department goals, affective

commitment will be higher.

H2A: People who score high on empowerment impact, will score high on affective

commitment.

The dimension meaning is also assumed to be related to affective commitment. A

positive relation is expected between empowerment meaning and affective commitment.

Spreitzer (1995) and Liden et al. (2000) already showed a positive relationship between the

dimension meaning and organizational commitment. When an employee feels the work is

very meaningful and fits in with his personal ideals, a higher score of affective commitment

can be expected.

11

H2B: People who score high on empowerment meaning will score high on affective

commitment.

We do not know how empowerment competence will influence affective commitment.

On the one hand it might have a positive influence on the variable, because a feeling of

competence and confidence of one‟s capabilities to perform work activities can cause a sense

of willingness to stay in the organization and may motivate the employee to discuss the

organization with people from outside, influencing the degree of affective commitment. On

the other hand a strong belief in one‟s capabilities can also cause a sense of prevalence or

over-confidence. This independence may create a certain distance to the organization.

H2C: A relationship between empowerment competence and affective commitment is

expected.

The fourth dimension of empowerment is self-determination and is expected to be

positively related to affective commitment. Previous research has not indicated a relationship

between self-determination and affective commitment. However, Ashforth (1989), showed

that powerlessness, defined as “a lack of autonomy and participation” (P.207), is related to

work alienation. Thereby, when an employee feels he can decide on his own how to perform

his tasks, this can cause a sense of reciprocity, which probably causes a higher degree of

affective commitment.

H2D: A positive relationship between empowerment self-determination and affective

commitment is expected.

2.6 Extra analysis

Extra attention is paid to the last hypothesis formulated to describe a relation between self-

determination and affective commitment. Self-determination refers to the sense of autonomy

and the degree to which decisions can be made on how to perform a certain task. Affective

commitment subsequently refers to the employee‟s emotional attachment to, identification

with and involvement in, the organization. When it is assumed that reciprocity comes into

play by giving employees autonomy in their tasks causing a sense of self-determination, a

positive relationship with affective commitment can be expected. However, another approach

12

might also be possible. In this approach an inverted u-shaped relationship is expected. If the

degree of employees‟ self-determination is very low, because there is no opportunity for the

employees to make decisions about how to perform the task on their own, employees are

unlikely to be committed in an affective way to the organization. Contrary, if the degree of

employees‟ self-determination is very high, because they have the opportunity to decide a lot

of things on their own, a certain distance to the organization could arise, which could

influence the degree of affective commitment to the organization in a negative way. Finally,

affective commitment of employees will probably be highest, when the degree of self-

determination is moderate. This is not supported by any literature so far, but in this study the

inverted u-shaped relationship will be assumed.

H2D*: The relation of empowerment self-determination and affective commitment shows an

inverted u-shaped curve. When there is a moderated degree of self-determination affective

commitment will be high; when the level of self-determination is low or high, the relation with

affective commitment will be low.

An example of an inverted u-shaped relationship is shown in figure 2.1. The relationship

starts out to be positive, but on a certain degree, this relation is changing into a negative one.

For the relation between self-determination and affective commitment it is expected that from

a low level up to a moderate level of self-determination, the relation with affective

commitment is positive. Subsequently, the relation changes into a negative one.

2.7 Job engagement

Following Robinson et al (2004), researchers at the institute for employment studies (IES),

engagement is large in the consultancy market, but there is a lack of academic research in this

area. IES declares that engagement brings clear business benefits, but that raising and

maintaining certain engagement levels means making an effort, taking time and doing an

investment. In academic literature, engagement is defined in different ways. Kahn (1990)

describes personal engagement and personal disengagement as “behaviors by which people

bring in or leave out their personal selves during work role performances” (p.694). People

will, when engaged, employ and express themselves physically, cognitively, and emotionally

during role performances and be present in their job role. Schaufeli et al. (2002) define

engagement as the degree in which employees have an energetic and effective connection

with their work activities and see themselves as able to deal completely with the demands of

their job. In this article they define the concept from the perspective of the employee as “a

positive, fulfilling, work-related state of mind that is characterized by vigor, dedication, and

absorption” (p.74). In this article these three aspects are characterized as follows: vigor by

energy, dedication by involvement and absorption by attachment to one‟s job. Thus, first

vigor refers to energy, to the energy and willingness to put effort in one‟s work, both in daily

and normal situations and in difficult situations. When there is a lack of vigor, it could be that

workers just work to survive and will not achieve results in a difficult task. Second,

dedication is characterized by involvement in one‟s work, in which enthusiasm,

meaningfulness, inspiration, pride and challenge are experienced. When a worker is not

dedicated, he is probably not willing to signal opportunities for the organization. Finally,

absorption refers to the attachment to one‟s job, to be fully concentrated and hardly able to

detach oneself. A lack of absorption can also have the consequence of suboptimal outcomes,

because of a lack of concentration.

2.8 The interaction between job engagement and empowerment

In an environment in which there is a lot of competition and where employees are

autonomous, it is easier for them to commit themselves to their jobs than to the organization.

Engaging employees to the organization might be very important in a situation in which

employees, knowledge workers, may be at risk of losing the necessary connection with the

organization to perform their jobs. Previous research has shown that engagement is the

antipode of burnout (Schaufeli et al, 2006), leads people to behave altruistically and behave as

14

good team players (Robinson, 2004), and influences company success (Harter et al, 2002).

These are important aspects influencing the performance of the organization.

As already been mentioned, job engagement influences the employee‟s behavior and

attitude. In this research the role of job engagement in the relationship between empowerment

and affective commitment is further examined. Does job engagement strengthen the

relationship between the dimensions of empowerment and affective commitment, or in the

contrary, does it weaken the relationship? Previous research showed a positive relationship

between job engagement and several outcomes, so we expect a change in the relationship

between empowerment and affective commitment when the relationship is moderated by job

engagement.

H3: The relationship between empowerment and affective commitment is moderated by job

engagement.

2.9 The interaction between job engagement and the dimensions of empowerment

In this study, hypotheses are also formulated in order to test interactions between the

dimensions of empowerment and job engagement and the influence on affective commitment.

Previous research has not investigated these relations yet. For this reason, assumptions will be

made and the hypotheses are exploratory. It is plausible to think that the highest affective

commitment will be reached by a high degree of empowerment impact in combination with a

high degree of job engagement. When an employee has the feeling that he can influence the

organizational outcomes by doing his or her job, and besides is very concentrated to do the

job and wants to put a lot of effort in the job, high affective commitment can be expected.

H4A: The positive relation between impact and affective commitment is stronger for

employees which score high on job engagement.

When an employee scores high on the dimension of empowerment meaning, the

moderator job engagement will positively influence the relationship with affective

commitment. The assumption is that a high identification with the organizational goals causes

more satisfaction in work and this in combination with absorption in the job will lead to a

higher affective commitment to the organization. When an employee scores low on the

dimension meaning, we expect a low score on affective commitment, and we do not expect

15

affective commitment to be higher when the employee‟s job engagement is high. On the

contrary, we expect even a lower score on affective commitment in case the employee is very

engaged in his job. This is assumed because the employee does not identify his own goals

with the ones of the organization, which is not really satisfying. Besides he is concentrated to

his work activities and this causes a chance that the employee is not really committed to the

organization and is not really involved with the willingness to stay there.

H4B: The positive relation between meaning and affective commitment is stronger for

employees which score high on job engagement. This is only the case when an employee

already scores high on empowerment meaning.

The direction of the hypothesis set up to test the direct relationship between

empowerment competence and affective commitment is not mentioned. Because we do not

know if a high degree of competence is likely to cause a distance to the organization, or on the

contrary, a willingness to stay in the organization, we do not know for sure what happens

when the moderation occurs. We assume the relationship in both cases is influenced by job

engagement.

H4C: The relationship between competence and affective commitment will be moderated by

job engagement.

In the direct hypothesis, a positive relationship between empowerment self-

determination and affective commitment is expected. When an employee has the feeling he

can determine the way he performs his tasks, and he is very engaged in his job as well, there

is a chance a certain distance arises between the employee and the organization. For this

hypothesis we assume the positive direct relationship changes into a negative one when the

moderator job engagement comes into play.

H4D: The interaction between self-determination and job engagement causes a negative

influence on affective commitment.

16

2.10 Trust in management

Trust is defined by Mayer & Davis (1995) as “the willingness of a party to be vulnerable to

the actions of another party based on the expectation that the other will perform a particular

action important to the trustor, irrespective of the ability to monitor or control that other

party.” (P.712) In this research it refers to the willingness of the employee to trust the

management in their actions. Previous research by Konovsky and Pugh (1994) has already

shown that trust in supervisors was positively related to organizational citizen behavior.

Furthermore, research by Whitney (1994) has shown that trust in organizational authorities

influenced subordinates' attitudes and behaviors. Being aware of the competitive environment

and the characteristics of knowledge workers and their unwillingness to share knowledge, it is

assumed in this research that trust in management can influence the relationship between

empowerment and affective commitment. Besides, research by Allen and Meyer (1990) has

already shown a strong correlation between dependability and affective commitment (p.61).

Dependability is defined here as the degree in which the organization can be trusted to behave

as it said it would.

2.11 The interaction between trust management and empowerment

We expect that the degree of trust in management will influence the relationship between

empowerment and affective commitment. In specific, we assume the relationship between

empowerment and affective commitment will be moderated by trust in the management.

H5: The relationship between empowerment and affective commitment is moderated by trust

in the management. In such a way that, when trust in management is high, the relationship

between empowerment and affective commitment will be stronger.

2.12 The interaction between trust management and the dimensions of empowerment

Hypotheses are also formulated in order to test interactions between the dimensions of

empowerment and trust in the management on affective commitment. An interaction effect

between empowerment impact and trust in management is expected. It is assumed that when

an employee feels he has a lot of influence on the organizational outcomes and trusts the

management, this could improve affective commitment. However, we assume the interaction

effect of a high degree of trust in management is stronger for an employee scoring low on

impact.

17

H6A: The positive relation between impact and affective commitment is enhanced when

employees are high on trust in management. This effect is stronger when empowerment

impact is low than when empowerment impact is high.

When an employee can identify his personal goals and ideals with those of the

organization, the trust in management will play a less important role in the degree of affective

commitment than in case the employee cannot identify his personal goals and ideals with

those of the organization.

H6B: The positive relation between meaning and affective commitment is enhanced when

employees are high on trust in management. This effect is stronger when empowerment

meaning is low than when empowerment meaning is high.

In the previous hypotheses we did not know for sure how the dimension empowerment

competence would influence affective commitment. When an employee feels very competent

in his or her work, it is assumed that an interaction with trust in management would have a

positive influence on affective commitment.

H6C: The interaction between competence and trust in management effects affective

commitment in such a way that affective commitment will be higher when trust in

management is high.

In the direct hypothesis a positive relationship between empowerment self-

determination and affective commitment is expected. In this study it is assumed that self-

determination interacting with trust in management has a positive influence on affective

commitment.

H6D: The positive relation between self-determination and affective commitment is stronger

for employees which are high on trust in management. This effect is stronger when

empowerment self-determination is low than when empowerment self-determination is high.

3. Relevance, Research Goal & Contribution

3.1 Relevance

In order to remain attractive for the current and the next generation employees, it is important

for organizations to (re)consider their policy in the rapidly changing environment. In the past

it has always been accepted that people could exercise power over the behavior of others. This

not only applies to society, but to companies and their employees as well (Malone, 2004).

During the transition phase of the industrial economy to the knowledge economy, a lot has

changed, and the focus has shifted away from the manual worker to the knowledge worker.

Today‟s society is characterized by increasing individualization and the development

of information technology. The trend of individualization is noticed in business life in the way

that people are more demanding and attach more value to freedom, flexibility and creativity.

Further development of information technology, causing lower communication costs, also

influences business life. When information sharing becomes easier, organizations can also

operate outside their boundaries. Within organizations, information technology also plays an

important role. It has enabled the revolution in business life as to dealing with power and

control, mentioned by Malone (2004). Moreover, it has enabled employees to share more

information in a faster way. Besides, physical presence is hardly necessary anymore. In all, it

has led to a new world of working.

Erasmus@work, a research program by the Erasmus University, started the New

World of Work project. The aim of this project is to gain knowledge of and insight in new

ways of working. Within this project several innovative organizations are participating. Some

of the consequences mentioned by the new ways of working are for example an increase in

access to information, changes in decision making and the flexibility of workplace and

working hours. The knowledge workers' desires, globalizing organizations together with the

flexibility and possibility to work without physical presence led to the contemporary result-

oriented organization. This new way of working also forces organizations to rethink their

policies. A concept that relates to the new ways of working, taking into account control,

current working environment, and the desires of the knowledge workers, is the concept of

empowerment. When people are given empowerment, is there a risk of losing the employees‟

connection with the company? Literature focuses on creativity and productivity, but what

happens to the employees‟ attitude toward the company? Committed employees deliver many

benefits for the organizations. Affective commitment is assumed to be positive related to

behaviors that are beneficial to the organization, such as performance, attendance, and staying

19

with the organization (Mathieu & Zajac, 1990; Meyer & Allen, 1997; Mowday, Porter, &

Steers, 1982, Randall, 1990).

In short, working environments require research, especially when organizations are

result-orientated and people‟s physical presence is not necessary anymore. Business

environment and people‟s attitudes are changing and it is important to be aware of the

consequences.

3.2 Research goal

The new ways of working are fairly new in our current society. For this thesis we want to

obtain better insights in the effects of empowerment on the willingness to stay in the

organization within this new world of working. Empowerment, a concept which is often heard

nowadays, will be the focus of this research. This concept can be divided into four

dimensions: impact, self-determination, meaning and competence. In this research we use

these four dimensions to gain a better insight and to find out how each dimension of

empowerment influences a variable that has to deal with commitment to the organization and

the willingness to stay in the organization, affective commitment. However, apart from the

positive image of the concept of empowerment, could a company empower its employees too

much? In general, is there a positive relationship between empowerment and commitment, an

increase in empowerment causing an increase in commitment, or could this relationship

change when a certain degree of empowerment is reached? In other words, is there a risk of

losing the employees‟ connection with the company caused by allowing them too much

empowerment? As has already been discussed, affective commitment is positively related to

behaviors that are beneficial to the organization, such as performance, attendance, and staying

within the organization. For this research it is an assumption that a high degree of

commitment to the organization is important for the organization‟s outcomes, which is also in

line with previous research. Thereby we assume, taking into account the characteristics of

knowledge workers and the competitive environment of today, that empowerment, trust and

job engagement can play an important role. To reach the research goal the following research

question has been formulated:

How does empowerment influence the employee‟s affective commitment to the organization

and what is the role of job engagement and trust in management in this relationship?

20

3.3 Contribution

This thesis contributes to academic literature as well as to practice. For this thesis we want to

gain better insight into the effect of providing empowerment to knowledge workers, taking

into account the new (flexible) working environment with rapidly changing technologies. By

rapidly changing technologies we mean technologies which enable us to work in a flexible

way, for example by cloud computing, virtual working, etc. As already been stated, we will

assess the four dimensions of empowerment in relation to affective commitment. Previous

research (Laschinger et al., 2000) has shown a positive relation between empowerment and

affective commitment. However, the effect of the dimensions of empowerment on affective

commitment has not been established previously. In addition to testing these direct

relationships, the examination of the effect of job engagement and of trust in management will

contribute to already existing literature about empowerment. With the New World of Work

project, RSM@work focuses on three elements, the three P‟s: People, Planet and Profit. The

first element, People, focuses on the working conditions, flexibility, work/life balance and

employee satisfaction. The second P, Planet, focuses on the impact on the environment and

the last P, Profit, focuses on productivity and creativity. In this thesis we will make a

contribution to the People element. Several relations between empowerment and outcome

variables regarding the People element within the New World of Work have already been

examined. However, the relation between the dimensions of empowerment and affective

commitment has not been examined before.

One of the organizations participating in the project of the New World of Work is

Rabobank. Rabobank has an internal program which holds for the entire organization, called

Rabo Unplugged. The program focuses on giving employees responsibility and autonomy in

job performance. In recent years this program was implemented gradually. Research data has

been collected from employees working at Rabobank. The research will focus on two

departments and three locations of Rabobank. These departments just started the

implementation of the unplugged project. Rabobank will put this thesis to practical use by

gaining a better insight in the dimensions of empowerment, in the influence of job

engagement and in trust in management and in the relationship with affective commitment in

the unplugged environment. It will help to improve managing the employees working at

Rabobank. Besides, other organizations can benefit. It will help to improve managing

employees working in organizations implementing a comparable project.

5. Research methods

5.1 Sample

In this thesis, the participants are Dutch Rabobank employees in two divisions: banking

operations, and concern purchase. The research will focus on two departments and three

locations of Rabobank. The first department, Banking operations, consists of Marketing

Support (MaS), Site Management (SiM) and a customer service center. The second

department is a purchase center. Since spring 2010 the Marketing Support and Site

Management sections have moved to a new unplugged environment in Boxtel. However, both

sections have been in the process for as long as two years. Apart from gathering data from

these two sections, also data is collected from employees working in the customer contact

center in Tilburg. These people have not moved to the unplugged building and only have the

opportunity to work in the office. Finally, data was collected from the purchase department in

Eindhoven. In Eindhoven people have been unplugged for a longer period already and have

been working with a lot of unplugged dimensions. The participants included both executing

employees and managers of various educational backgrounds, all varying in age. Besides, the

employees have been working in different employments.

5.2 Procedure

The data used for this research is gathered on one moment in time and with one and the same

survey distributed to the three locations. For this research potential participants included 408

employees that could fill out the survey online. Questionnaires were distributed online by a

member of the department. Each questionnaire had an accompanying letter to explain the

purpose of the questionnaire. Employees were asked to share their experiences and opinions

with the new unplugged working approach and environment of RABO bank. Participation

was voluntary, but because of a low initial response rate, employees were requested to

cooperate. Finally, we were able to gather useful data among 184 participants. When we put a

10 minutes' limit on the time allowed for filling out the survey, we filtered out one participant,

who could not satisfy this requirement.

5.3 Measures

Each variable has been measured in the survey according to the constructs defined to

represent the particular variable. The entire list of measured items can be found in appendix

A.

5.3.1 Empowerment

The concept of empowerment can be defined as giving someone the right to make a decision

while this right previously belonged to someone else. In this research we will focus on

psychological empowerment, or the employee's perception of empowerment. The degree of

empowerment was measured by using the 12 items in Spreitzer's article (1995). In this article

empowerment is divided into four dimensions. These four dimensions are meaning,

competence, self-determination and impact. The validation of these four dimensions allows us

to accurately examine behaviors that lead the employee to feel empowered (Gómez & Rosen,

2001). Each dimension is measured by three items. An example of one of the items to

measure meaning is: „My work activities have a personal meaning to me‟. The Cronbach‟s

Alpha of meaning is .81. An example of one of the items to measure competence is: „I have

confidence in my ability to do my work‟. The Cronbach‟s Alpha of competence is .69. An

example of one of the items to measure self-determination is: „I can decide for myself how I

should tackle my work‟. The Cronbach‟s Alpha of self-determination is .88. And an example

of one of the items to measure impact is: „I have considerable influence in what goes on

within my department‟. The Cronbach‟s Alpha of impact is .85. The items are measured on a

scale ranging from totally disagree (1) to totally agree (5).

5.3.2 Affective commitment

Affective commitment refers to the employee‟s emotional attachment to, identification with

and involvement in the organization and was measured by using a part of the three component

conceptualization of organizational commitment, composed by Allen and Meyer (1990). De

Gilder et al. (1997) formulated a Dutch version of this construct. In this Dutch version some

items are defined differently. The direct translation into Dutch led to lengthy definitions.

Together with the negatively defined items, this brought down the validity of the scale. The

Dutch writers argue that these items were „bad for the psychometric characteristics‟ (p.97).

For this reason we have used the version of the scale in Dutch. An example of one of the

items to measure affective commitment is: „I really feel as if this organization‟s problems are

26

my own‟. The items are measured on a scale ranging from totally disagree (1) to totally agree

(5). The Cronbach‟s Alpha of affective commitment is .87.

5.3.3 Job engagement

In this research, the concept of job engagement is defined as the degree in which an employee

is attentive and absorbed in his performance of the job. The concept will be measured using

the three aspects absorption, dedication and vigor. In the survey each aspect is measured by

three items formulated by Schaufeli et al. (2006). An example of one of the items to measure

absorption is: „When I am working, I forget everything around me‟. An example of one of the

items to measure dedication is: „My work inspires me‟. And an example to measure vigor is:

„I am full of energy at work‟. Job engagement is evaluated on a scale ranging from totally

disagree (1) to totally agree (5). The Cronbach‟s Alpha of job engagement is .86

5.3.4 Trust in management

In this research, the concept of trust management is defined as employees' perceptions of the

level of their trust in management's honesty and competence to make effective decisions. The

concept of trust management is measured by four items based on the article of Cook and Wall

(1980). An example of an item to measure trust management is: „The management carries out

its tasks efficiently, as far as I can assess‟. The Cronbach‟s Alpha of trust in management is

.83.

5.3.5 Control variables

The control variables used in this research are age and employment. Age is measured by

asking people their age. For this research it is assumed that the age of the employee can have

an influence on the affective commitment to the organization. Research by Finegold et al.

(2002) already indicated a significant influence of age on variables that predict commitment

and the willingness to stay in the company. Employment is measured by asking the question:

„How many hours per week do you spend on your work on average?‟ This concerns the actual

total number of working hours, including overtime, meetings, business travel and education.

This research covered participants with several employments. In this research it is assumed

that the average number of working hours can influence affective commitment. It is plausible

to think that an employment of 16 hours a week in comparison with an employment of 40

hours a week can cause a difference in one‟s identification with and attachment to the

organization.

6. Results

6.1 Factor Analysis

Factor analyses can be used for different purposes. For example, it can be useful to reduce

variables to a smaller number of dimensions or to investigate if items are measuring aspects of

an underlying dimension (Kim & Mueller, 1978). In this research a factor analysis is

performed of empowerment. In table 6.1 the loadings on the four dimensions of

empowerment are shown. In this factor analysis the Varimax rotation method is used. When

using this method it is desired to have an obvious variance between high and low loadings.

Moreover, it is important and desired that variables only have high loadings on one factor.

Following the article of Tinsley and Tinsley (1987) a rule of thumb is factor loadings of .30

are acceptable. Therefore, loadings should be at least .30

When assessing the factor loadings, it is obvious that the factors are not loaded in a

perfectly satisfying way. First, empowerment appears to consists of only three factors instead

of four. In specific, out of this figure emerges no obvious distinction between the dimension

of self-determination and impact. Secondly, one item should be removed from the second

factor measuring the dimension meaning. One item of the dimension impact has a fairly high

value on this factor. Which further meets the requirements of a satisfying factor. Thirdly, the

loadings on competence are not perfectly loaded; one item hardly meets the rule of thumb of

.30. Besides, this item has a much higher value in the fourth factor.

Despite these shortcomings, it is chosen in this research to continue with the four

dimensions of empowerment, containing three items per dimension. The four dimensions of

empowerment are common and widely accepted. Besides, previous research argue that each

of the four dimensions of empowerment adds a unique facet to the individual‟s experience of

empowerment (Thomas & Velthouse, 1990). Finally, we have evaluated the Cronbach

Alpha‟s of the four dimensions. Three dimensions scored above .80, which is satisfying, and

only competence scored .689, which is still acceptable. When removing one item, the

Cronbach‟s Alpha only slightly improves.

6.2 Correlations

This research aims to investigate the relationship between empowerment and affective

commitment. First, we will evaluate the direct influence of empowerment, divided into

subscales, on affective commitment. In addition, we examine the effect of two moderators,

trust in management and job engagement, on this relationships.

In order to determine if there are linear relationships between the subscales of

empowerment and affective commitment, we evaluated the correlations and their significance.

The correlations between the variables are shown in table 6.2.

Direct relationships with dependent variable

Meaning and affective commitment are positively correlated, and significant. Competence

and affective commitment are positively correlated, but marginally significant. This means

that the relationship is significant on 10% instead of on 1% or 5%. Self-determination is

positively correlated to affective commitment, but also marginally significant. Impact and

affective commitment are positively correlated and significant.

Independent variables

The four dimensions of empowerment are positively related and significant. Strong relations

emerge between impact and self-determination as well as between impact and meaning.

Independent variables and job engagement

Job engagement and the dimensions of empowerment are positively related and significant.

31

Independent variables and trust management

Trust in management and the dimensions of empowerment are positively related. However,

not all relationships are significant. The relationship between meaning and trust in

management and the relationship between impact and trust in management proves to be

significant.

Job engagement, trust management and affective commitment

Job engagement is positively related to affective commitment and is significant. Trust in

management and affective commitment have a positive relationship which is also significant.

Control variables

Gender is slightly related in a positive way to affective commitment, but is not significant.

The relation between employment and affective commitment also appears to be positive and

is marginally significant.

Squared self-determination

In the hypotheses an extra hypothesis is set up in order to get a better insight in the dimension

self-determination. In specific, an inverted u-shaped relationship is expected between self-

determination and affective commitment. As expected, positive correlations are found with

the three other dimensions of empowerment. Besides, a marginally significant relationship

with affective commitment is shown in the table.

Some correlations are remarkably high, for example between job engagement and meaning

and between self-determination and impact. In the next paragraph there will be paid more

attention to these observations.

32

6.3 Regression analysis

Regression analysis is used to analyse and to understand how the value of a dependent

variable, in our case affective commitment, changes or is influenced by changing the value of

an independent variable when others are held constant. Before we set up a regression

analysis, the means were centered, this is done to reduce multicollinearity (Aiken & West,

1991).

6.3.1 Exploring Regression Analysis: Empowerment divided in four dimensions

Several regression analyses need to be performed in order to determine a final model. In order

to get a first impression of the relationships between the variables of the dimensions of

empowerment, affective commitment and two moderators, a regression analysis is performed,

which includes all assumptions made for the hypotheses. This model, attached in appendix B,

consists of six steps, and each step adds new variables to the model. In the first step, the

control variables age and employment have been added in order to determine if they would

influence the dependent variable affective commitment. By adding these control variables,

each next step will be controlled for these variables. The model shows in the first step age has

no significant influence (β = .06, P = 0.401) and employment has a marginally significant

influence (β = .14, P = 0.066). This means that the variable is significant on 10% instead of

the desired 1% or 5%.

In the second step the four dimensions of empowerment are added to the model. In this

step employment is no longer marginally significant (β = .06, P = .442). The model shows a

positive causal relationship between the dimension meaning and affective commitment (β =

.49, P = 0.000). The other dimensions of empowerment are negatively related to affective

commitment. However, these relationships are not significant.

In the third model, job engagement and trust management are added to the model. In

this model the control variable employment is significant again (β = .18, P = .016). Besides,

the relation with the dimension meaning remains significant, however the significance

changed from 1% (P= 0.000) to 5% (P = 0.043) and the three other dimensions stay

insignificant. The significance of the two new variables is 1%.

In the fourth model the two-way interactions with job engagement are added to the

model. This step shows one significant interaction, namely the one with the dimension

competence (β = -.19, P = 0.04).

In the fifth model the interactions with trust management are added to the model. The

model shows three significant interactions. The interactions with impact (β = .25, P = 0.007)

33

and meaning (β = -.24, P = 0.004) are significant on 1% and the interaction with competence

(β = .189, P = 0.014) is significant on 5%. The interaction with self-determination is negative

and almost marginally significant (β = -.14, P = 0.108). Finally, the interaction between

competence and job engagement is still significant (β = -.31, P = 0.002).

In the sixth step the squared term self-determination is added to the model. The direct

influence of meaning is changed into a marginally significant influence (β = .19, P = .060).

Besides, the interaction between competence and job engagement is stronger and still

significant (β = -.29, P = .004). Significant interactions still exist for three dimensions of

empowerment. The interaction between self-determination and trust management is less

significant in this step (-.128, P = .144). However, squared self-determination shows a

negative and significant relation with affective commitment (β = -.17, P = .035). This model

has served as an exploring model and for a first impression.

Trust in the management showed to be a very significant moderator in the relation

between the dimensions of empowerment and affective commitment. However, in the

relationship with job engagement, empowerment and affective commitment, only the

interaction between competence and job engagement shows a significant effect. Therefore we

can already reject hypotheses H4A, H4B and H4D. With these results a new model is set up,

in which only the significant interaction between job engagement and competence is

preserved. Furthermore, all interactions, significant and insignificant, with trust in

management remain in the model. Although the insignificant interactions with job

engagement have been removed from the model, the insignificant interaction between self-

determination and trust management is preserved. This is on account of the P-values, which

were very high in the insignificant interactions between job engagement and the dimensions

of empowerment and less high in the interaction between trust management and self-

determination (β = -.13, P = .14). To examine if significant interactions between squared self-

determination and job engagement and between squared self-determination and trust

management exist, two new steps were added to the model. After this, the model was not

significant anymore. For this reason we let these steps out of our final regression model.

6.3.2 Final Regression Analysis: Empowerment divided in four dimensions

The results of the adjusted and final regression are shown in table 6.3. The regression model

consists of 6 steps and each step adds some new variables to the model. In the first step the

control variables age and employment are added to test if they influence the dependent

variable. By adding these variables, each next step will be controlled for these variables. In

34

the first step, the results show no significant influence of the control variable age, however

there is a slightly marginally significant influence of employment (β = .14, P = 0.066).

In the second step, the four dimensions of empowerment are added to the model. The

influence of the control variable employment is not marginally significant anymore. The

model shows that the dimension meaning is significant on 1% (β = .49, P = .000).

In the third step, job engagement and trust management are added to the model. In this

model one of the control variables, employment, is significant on 5 %. Besides, the dimension

meaning is still significant (β = .19, P = .043) and also the newly added variables job

engagement and trust management are significant on 1%.

In the fourth step, the two-way interaction of job engagement and competence is added

to the model and shows to be significant (β = -.16, P = .007).

In the fifth step, two-way interactions with trust management are added and all the

interactions are significant. Only the interaction with self-determination is marginally

significant; this means that the interaction is significant on 10% instead of the desired 1% or

5%. The interaction with competence is significant on 5% and the interactions with meaning

and impact are significant on 1%. Besides, the interaction between competence and job

engagement stays significant on 1% and the direct relation between meaning and affective

commitment also still exists in this model and is significant on 5%.

In the sixth step squared self-determination is added to the model. In this model the

direct relation between meaning and affective commitment is marginally significant (β = .16,

P = .084). The interaction between job engagement and competence still exists. Besides, three

interactions with trust management exist, only the interaction between self-determination and

trust management does not exist anymore. However, there is a significant relation between the

squared self-determination and affective commitment (β = -.15, P = .040).

6.3.3 Multicollinearity

In the correlation matrix high correlations were found for some of the variables. For this

reason the tolerance values are evaluated to check for multicollinearity. The rule of thumb

according to Van Dalen and De Lede (2009) is that there is no reason to suspect

multicollinearity when the tolerance value is above 0.2 and the Variance Inflation Factor

(VIF) is below 5. The final regression model shows a lowest tolerance value of 0.742 and a

highest VIF score of 1.348, for this reason multicollinearity is not plausible. The tolerance

values and the values of the Variance Inflation Factors are available in appendix C.

6.4 Hypotheses testing

In this paragraph first the hypotheses are tested to examine the direct effects of empowerment

on affective commitment. After this, the hypotheses are tested to examine the role of two

moderators in the relationships. The hypotheses are tested using the final regression model

(table 6.3).

6.4.1 Relationship between empowerment and affective commitment

Hypothesis 1 predicts a relationship between empowerment and affective commitment. To

examine the direct influence of the dimensions on the dependent variable, not taking into

account the possibility of the influence of moderators, the results of step 2 of the final

regression model are evaluated. The results of this step show no significant influence of the

control variables age and employment. The dimension of meaning is positive and significant

(β=.49, P=0.00). The other three dimensions show a negative beta and are not significant.

This model explains 22% of the total variation in affective commitment (Rsquare =.22, P =

0.00). When we take into account the number of dependent variables, this model explains

20% of affective commitment (adjusted Rsquare = .195, P=0.00). Hypothesis 1 is partly

supported. The assumption was that the dimensions of empowerment would have an effect on

affective commitment, however only the dimension meaning is directly and positively related

to affective commitment, as well as significant.

6.4.2 Relationships between dimensions empowerment and affective commitment

In hypothesis 2 relationships between the dimensions of empowerment and affective

commitment are predicted. Hypothesis 2A predicts a positive relationship between the

dimension impact and affective commitment. In the sixth step the relationship is weak and not

significant (β = -.12, P = 0.16). The table shows no significant causal relation between impact

and affective commitment. Hypothesis 2A is not supported.

Hypothesis 2B predicts a positive relationship between meaning and affective

commitment. The table shows that from the second step up to the sixth step this relationship is

indeed positive and significant. However, the strength of the relationship varies in the

different steps. In the second step the relationship is the strongest (β= .49, P=0.00). In

subsequent steps the relationship is a little weaker and less significant. However, in the sixth

step the relation still is positive and marginally significant (β = .16, P=0.084). Thus,

hypothesis 2B is supported.

37

Hypothesis 2C predicts a relationship between competence and affective commitment.

As this relationship could not be observed, the direction could not be determined either. The

model shows no significant relationship between the dimension competence and affective

commitment. A very weak negative relationship is shown, but this relationship is not

significant (β = -.02, P = 0.805). A significant direct causal relationship is not found between

competence and affective commitment, thus hypothesis 2C is not supported.

In hypothesis 2D a positive relationship between self-determination and affective

commitment is expected. The model shows no significant relationship between self-

determination and affective commitment. In the sixth step the relationship shows to be

negative and very weak, and besides is not significant (β = -.14, P = 0.151). No direct positive

causal relationship is found between the dimension of self-determination and affective

commitment. Thus, hypothesis 2D is not supported.

6.4.3. Moderating effect of Job engagement

In this paragraph the hypotheses set up to test the relations involving job engagement are

discussed. We will test if the relationship between empowerment and affective commitment is

moderated by job engagement. In the sixth step, the model shows job engagement (β = .36, P

= 0.00) is positive and significant. In hypothesis 3 a moderating effect of job engagement is

expected in the relationship with affective commitment. The model only shows a significant

interaction between competence and job engagement on affective commitment. The

hypothesis predicted an overall moderating effect, so that hypothesis 3 can partly be

supported. During the examination of the exploring regression model, no significant

interactions could be found between job engagement and impact, meaning and self-

determination. For this reason only the interaction between job engagement and competence

is discussed.

In hypothesis 4C a moderating effect of job engagement is expected in the relationship

between the dimension of competence and affective commitment. No direct effect between

competence and affective commitment has been found (β = -.02, P = 0.805). In the sixth step

of the regression model, a significant interaction is shown (β = -.18, P = 0.008).

6.4.4. Moderating effect of trust in the management

In this paragraph the hypotheses set up to test relations with trust in management are

discussed. We will test if the relationship between empowerment and affective commitment is

38

moderated by trust in management. In the sixth step, the model shows trust in management (β

= .28, P = 0.00) is positive and significant.

In hypothesis 5 a moderating effect of trust in the management is expected in the

relationship with affective commitment. For three dimensions of empowerment, the model

shows significant interactions with trust in management. Overall we find a significant

influence of the moderator trust in management on the relationship between empowerment

and affective commitment. Therefore hypothesis 5 is supported.

First, the moderating effect of trust in management in the relationship between impact

and affective commitment is discussed. In hypothesis 6A a two-way interaction between

impact and affective commitment is expected. The model shows a two-way interaction effect.

The model shows a negative direct effect, however this relationship is not significant (β = -

.12, P = .16). The sixth model shows a significant two-way interaction between trust in

management and impact (β = .23, P = 0.008).

Secondly, the moderating effect of trust in management in the relationship between

meaning and affective commitment is discussed. In hypothesis 6B a two-way interaction

between meaning and affective commitment is expected. The model shows a two-way

interaction effect. A direct and positive relationship is shown in the second and in each next

step of de model. However, the direct relationship between meaning and affective

commitment differs in the steps. In the second step the direct relationship is stronger and more

significant (β = .49, P = 0.000) than in the sixth step (β = .16, P = 0.084). The model shows in

step six a significant two-way interaction between meaning and trust in the management (β =

-.21, P = 0.004).

The third moderating effect of trust in the management is shown in the relationship

between competence and affective commitment. In hypothesis 6C a moderating effect of trust

in management is expected in the relationship between competence and affective

commitment. The model shows a negative direct effect of competence on affective

commitment, however this relationship is not significant (β= -.016, P=0.805) No direct and

significant effect in the relationship between competence and affective commitment is shown.

In step six an interaction effect between competence and affective commitment is shown in

the model and is significant (β = .16, P = 0.028).

Finally, the moderating effect of trust in management in the relationship between self-

determination and affective commitment is discussed. In hypothesis 6D a moderating effect of

trust in management in expected in the relationship between self-determination and affective

commitment. The model shows a slightly negative direct relationship. However this

39

relationship is not significant (β = -.14, P = 0.151). No direct effect in the relationship is

found. In step 6 an interaction effect is shown in the model, however this interaction is not

significant (β = -.131, P = 0.127).

6.4.5. Final results interactions

The regression model showed one significant interaction between job engagement and the

dimension competence, and in addition the model showed three significant interactions

between trust in management and the dimensions of empowerment. These interactions are

assumed to affect the degree of affective commitment. To get a visual indication of the

effects, the significant interactions are plotted in the figures below. By means of these figures,

the hypotheses will be evaluated.

Hypothesis 4C predicts the relationship between competence and affective

commitment would be moderated by job engagement. The visualization of the significant

two-way interaction of competence and job engagement is shown in figure 6.1. The highest

degree of affective commitment is related to a low score on competence and a high score on

job engagement. This two-way interaction indicates that when an employee does not have the

feeling that he or she is competent and can perform his work activities very well, the degree

of job engagement influences his affective commitment to the organization. In specific, when

the employee is very concentrated in performing his tasks and wants to put a lot of effort in

the job as well, affective commitment will be high. However, when he already experiences a

high degree of competence, his engagement to the job will not influence the relationship with

affective commitment. Hypothesis 4C is supported.

Hypothesis 6A predicts that the positive relation between impact and affective

commitment is stronger for employees who are high on trust in management. It is expected

that this effect is stronger when empowerment impact is low than when empowerment impact

is high. The visualization of the significant two-way interaction of impact and trust in

management is shown in figure 6.2. The highest degree of affective commitment is achieved

when both impact and trust in management are high. This two-way interaction shows that

when an employee feels his or her work activities have significant influence on the

organizational outcomes, the way in which the employee trusts the management influences his

or her affective commitment to the organization. The highest and lowest degree of affective

commitment relate to the employee who feels he has a great influence on the organizational

outcomes. In specific, an employee who scores high on impact and has a high degree of trust

in management, will score high on affective commitment. Conversely, the lowest score on

40

affective commitment relates to the employee who has no trust in the management. However,

for an employee who does not experience a great sense of influence of his or her work

activities on the organizational outcomes, the degree of trust in management does not lead to

more affective commitment to the organization. Hypothesis 6A is partly supported.

Hypothesis 6B predicts a positive relation between meaning and affective commitment

is enhanced when employees are high on trust in management. This effect is stronger when

empowerment meaning is low than when empowerment meaning is high. In figure 6.3 the

visualization of the significant two-way interaction of meaning and trust in management is

shown. The highest degree of affective commitment is related to a low score on meaning and

a high score on trust in management. This two-way interaction indicates that the role of trust

in management is important when an employee cannot identify his or her personal ideals with

the organizational ideals and goals. Conversely, when the employee is able to identify his

personal ideals with the ones of the organization, trust in management makes no marked

difference to his affective commitment to the organization. Hypothesis 6B is supported.

Hypothesis 6C predicts that an interaction between competence and trust in

management effects in such a way that affective commitment will be higher when trust in

management is high. The visualization of the significant two-way interaction of competence

and trust in management is shown in figure 6.4. The highest degree of affective commitment

is reached when both competence and trust in management are high. This two-way interaction

indicates that when an employee feels he can perform his tasks very well, his trust in

management will influence his affective commitment . In particular, when the degree of trust

in the management of a competent employee is high, affective commitment will be high.

Conversely, when an employee who feels very competent scores low on trust in management,

the degree of affective commitment will be lowest. However, in the case of an employee who

does not feel very competent, the degree of trust in management will not make a marked

difference in affective commitment.

6.5 Extra analysis

At an earlier stage, two hypotheses have already been set up in order to get a better insight in

the relation between self-determination and affective commitment. The first hypothesis

predicts that self-determination is positively related to affective commitment. The second

hypothesis 2D*, set up to examine another possible relationship between empowerment self-

determination and affective commitment, predicts that the relation between the two shows an

inverted u-shaped curve. It is assumed that a moderate degree of self-determination will lead

to a high level of affective commitment, whereas a low or high level of self-determination

will show a low level of affective commitment. In the regression model the sixth step does

indeed show a significant inverted u-shaped relationship between self-determination and

affective commitment, the squared term for self-determination being negative and significant

(β = -.15, P = 0.040). In figure 6.5 this relationship is shown and a slightly inverted u-shaped

relationship is visualized. This supports our alternative hypothesis 2D*. Whereas an increase

from low to moderate levels of self-determination is associated with an increase in affective

commitment, affective commitment decreases at relatively high levels of self-determination.

7. Discussion

The aim of this study was to assess the effects of empowerment on the employees‟

commitment to the organization, by examining the relationship between the four dimensions

of empowerment and affective commitment. In this research the characteristics of the

knowledge workers and the environment they are working in nowadays are examined as well.

Literature already showed that the current knowledge worker needs a certain degree of

commitment to the job in order to perform well (Davenport, 2005). Moreover, working in the

society of today, people do not work in the same place all the time, are assessed by results

achieved, and are not always willing to share their knowledge. For these reasons we assume

that job engagement and trust in management influence the relation between empowerment

and affective commitment. Attention is given to the possibility of moderating effects of job

engagement and the employee's trust in the management.

First, the direct relations between the dimensions of empowerment and affective

commitment are discussed. The results of the study show certain direct relationships between

empowerment and affective commitment. In particular, a significant relation between self-

determination and affective commitment is shown and a relationship between meaning and

affective commitment. Self-determination is related to affective commitment in a curvilinear

way. At low and high levels of self-determination, employees are less committed than at

moderate levels. This result is in line with the alternative hypothesis formulated in order to

examine the relation between self-determination and affective commitment. Previous research

does not indicate such a curvilinear relation, but only show a linear relationship between a

lack of autonomy and work alienation. This relationship gives an indication for the relation

between self-determination and affective commitment. However, this study does not support

this relationship, but supports our alternative hypothesis, focusing specifically on the degree

of autonomy allowed to employees, revealing a certain risk in this respect.

Apart from the direct relationship between self-determination and affective

commitment, a direct relationship between meaning and affective commitment is found. This

result is also in line with the hypothesis mentioned earlier and is in line with literature

(Spreitzer, 1995 & Liden et al, 2000).

However, no direct relationships are found between impact and affective commitment

and competence and affective commitment. The two corresponding hypotheses formulated in

this study are not supported, which requires a new line of thinking. It could be true that these

two dimensions are not directly related to commitment to the organization, but to commitment

45

to the job instead. Besides, it might be due to the fact that only experiencing a degree of

impact or competence is not enough to influence affective commitment.

Secondly, indirect relations between the dimensions of empowerment and affective

commitment are discussed. A significant interaction between competence and job engagement

is found. This is in line with hypothesis 4C, which predicted that the relationship between

competence and affective commitment would be moderated by job engagement. In the

hypothesis formulated to test the direct relationship between competence and affective

commitment, the direction could not be assessed. In the literature review the chance of over-

confidence and independence has already been discussed. Moreover, the positive outcomes

caused by job engagement, that have already been assessed previously, are discussed, and

prove to be in line with the results of this study. Namely, the highest degree of affective

commitment is related to a low score on competence and a high score on job engagement. No

support is found for hypotheses 4A, 4B and 4D, predicting interactions with job engagement

and the three dimensions of empowerment impact, meaning and self-determination.

Apart from the significant interaction found between competence and job engagement,

a significant interaction is found with trust in management. This is in line with hypothesis 6C

which predicts a moderating effect of trust in management in the relationship between

competence and affective commitment. A high score on competence interacting with high

trust in the management is related to the highest score on affective commitment. Regarding

these interactions, it might be noted that the former is primarily related to a low score on

competence and the latter to a high score on competence to achieve the highest level of

affective commitment. However, we think experiencing a high degree of confidence in one's

capacities in combination with a high degree of engagement to the job will cause a distance to

the overall goal of the organization. Confidence in one's capacities in combination with a high

degree of trust in management, causing positive feelings towards the organization, will make

the employee more committed to the organization. However, no evidence is found for this

outcome and interpretation in literature.

Apart from these interactions, a significant interaction is found as well between trust in

management and the dimension impact. This is in line with the first part of hypothesis 6A

which predicted that the positive relation between impact and affective commitment is

stronger for employees who have a high score on trust in management. The second part of the

hypothesis, predicting the effect is stronger when empowerment impact is low than when

empowerment impact is high, is not supported. This might be due the fact that when an

employee does not feel he is really contributing to the goals of the organization, trust in the

46

management does not make a real difference to his commitment to the organization. This

might be due a feeling of meaninglessness. However, when the employee does feel he

contributes to the goals of the organization, the degree of trust in the management does make

a real difference.

Finally, a significant interaction is found between meaning and trust in management.

Which is in line with hypothesis 6B predicting a positive relation between meaning and

affective commitment is enhanced when employees are high on trust in management. This

effect is stronger when empowerment meaning is low than when empowerment meaning is

high. In other words, when the employee does not feel he can identify his personal goals with

the goals of the organization, but does trust the management, a certain degree of affective

commitment can still be achieved. However, the combination of a low identification with the

organization‟s goals and a low degree of trust in management causes a noticeable decrease in

the degree of affective commitment.

8. Conclusion

This chapter presents the final conclusions of the research. Before presenting these, it is

important to realize that employees‟ commitment to an organization is not self-evident. In

present-day environment in which there is a lot of competition between organizations as well

as between employees within an organization, we need more insight. In the current working

environment, in which the focus has shifted from the manual worker to the knowledge

worker, knowledge can be seen as a competitive advantage. A certain degree of autonomy and

a feeling of being of value are very important for employees. When knowledge workers view

their knowledge as a competitive advantage and have certain characteristics and desires, they

do not always share their knowledge. This might cause a loss of valuable knowledge when

they leave the organization.

In order to keep employees‟ knowledge within the organization, commitment to the

organization might be important. In this research we have focused on affective commitment.

Affective commitment refers to the employee‟s willingness to stay in the organization.

Affective commitment is positively related to behaviors that are beneficial to the organization

such as performance, attendance, and staying with the organization (Mathieu & Zajac, 1990;

Meyer & Allen, 1997; Mowday, Porter, & Steers, 1982, Randall, 1990).

A concept that relates to the preferred autonomy of employees is the concept of

empowerment. The focus of this research has been on the relation between empowerment and

affective commitment. The aim of this study was to examine the relation between the four

dimensions of empowerment and affective commitment. Apart from examining the direct

relations between the four dimensions of empowerment and affective commitment, attention

is also paid to the characteristics of the knowledge workers and the environment they work in

nowadays. This thesis has aimed to answer the following research question:

How does empowerment influence the employee‟s affective commitment to the organization

and what is the role of job engagement and trust in management in this relationship?

This thesis has identified a relationship between dimensions of empowerment and affective

commitment. The four dimensions of empowerment are meaning, impact, competence and

self-determination. However, not every dimension of empowerment is directly related to

affective commitment. The results showed that the dimension empowerment meaning is

positively related to affective commitment. This means that an employee who can identify his

48

personal beliefs with the goals of the organization shows more emotional attachment,

identification and involvement in the organization. In addition to this direct relationship, a

direct relationship is also shown between self-determination and affective commitment.

However, this is a curvilinear relationship. This means that the employee who experiences a

moderate degree of autonomy in performing his job, shows the highest degree of affective

commitment.

Apart from these direct relationships, significant interaction effects are also found with

job engagement and trust in the management. Two significant interactions are found with

competence. First, competence and job engagement have a significant interaction effect. More

specifically, for an employee who does not have the feeling that he or she is competent and

can perform his work activities very well, job engagement will influence affective

commitment. The importance of job engagement only applies when the employee does not

experience a high degree of competence. Second, competence and trust in the management

show to have a significant interaction effect. More specifically, when a competent employee

has great trust in the management, his affective commitment will be high. Conversely, when

his trust in the management is low, the degree of affective commitment will be lowest. The

importance of trust in the management only applies in the case of a very competent employee.

The results show another interaction effect between the dimension empowerment

meaning and trust in the management. In this interaction, trust in the management is important

when an employee cannot identify his or her personal ideals with the organizational ideals and

goals. The highest degree of affective commitment is related to a low score on meaning and a

high score on trust in management.

Lastly, the results show an interaction effect between the dimension empowerment

impact and trust in the management. The highest degree of affective commitment occurs

when both impact and trust in management are high. The highest and lowest degree of

affective commitment relate to the employee who feels he has a great influence on

organizational outcomes. However, in the case of the employee who does not experience a

great sense of influence of his or her work activities on organizational outcomes, the degree of

trust in management does not affect his commitment to the organization.

Overall these results suggest that organizations should become aware of the direct

effects of empowerment on affective commitment and of the interaction effects of job

engagement and trust in the management with the dimensions of empowerment on affective

commitment.

8.1 Strengths, limitations and future research

Previous research showed relations between the dimensions of empowerment and several

work-related outcomes. A relation between empowerment and commitment is supported by

previous research as well, even a relation with affective commitment has already been proven.

Affective commitment has been found to be beneficial for organizations. However, the

relations between the dimensions of empowerment and affective commitment are not shown.

The findings of this research demonstrate a relation between the dimensions of empowerment

and affective commitment. However, this relation is not that simple for each dimension, and

relations are not self-evident for each dimension either. For some of the dimensions, the

findings show the importance of interactions with trust in the management and job

engagement for a significant relation with affective commitment. One of the important

contributions of this research is that it underscores the different dimensions of empowerment.

Each dimension is related to affective commitment in a direct way or through moderation

with job engagement or trust in management. Another important contribution of this research

is the inverted u-shaped relationship found between self-determination and empowerment. In

previous research an inverted u-shaped relation between self-determination and commitment

or comparable organization outcomes has not been shown.

The measurements used in this research have all been validated in previous scientific

research, which endorses the reliability of the research. However, a number of limitations

should be considered when interpreting these findings. First, the factor analysis, used in order

to gain a better insight in the dimensions of empowerment, shows that the factors are not

loaded in a perfectly satisfying way. That is, the three items per dimension are not loaded in

the desired dimensions of empowerment. However, the four dimensions of empowerment are

common and widely accepted. Besides, previous research has argued that each of the four

dimensions of empowerment adds a unique facet to the individual‟s experience of

empowerment (Thomas & Velthouse, 1990). Furthermore, after evaluating the Cronbach‟s

Alpha‟s per dimension, each dimension is satisfying.

Secondly, a question that could arise from the foregoing is the reliability of the

respondents. Respondents were sampled from two departments working in three locations.

Possibly, respondents in different locations do not experience the unplugged environment in

the same way.

Thirdly, all measurements used are self-reports, therefore social desirability might

have affected the results. One must bear in mind that the measurements may not reflect the

actual performance of the respondents (Podsakoff & Organ, 1986). Fourthly, the research data

50

sample consists of 184 respondents, which is significant, but might be limited for

generalization to a larger population. In the fifth place, research data has been collected

within two departments of Rabobank. In order to make statements and judgements about other

departments of Rabobank, or about Rabobank in general, the results shown in this research

are not necessarily representative. This is because Rabobank has a lot of locations and

departments, having their own organizational culture.

Subsequently, taking into account the two different departments and the three different

locations, the sample cannot be described as homogeneous. It would be interesting to analyze

the groups separately. However, with a sample consisting of 184 respondents in all, separate

analysis would not yield in significant and reliable results.

Recommendations for future research are plentiful. First, replication of this research in

other organizations and in other industries could help to verify the current results. Possibly

this could be the next step to be able to generalize the results. Apart from a replication in other

organizations and in other industries, replication with a larger sample would be desirable.

Another possibility is to test other moderators in the relationship between

empowerment and affective commitment. For example, by measuring the degree to which the

employee is working outside the office and its possible effect on affective commitment in the

relationship with the dimensions of empowerment.

8.2 Practical implications

Previous research suggests that empowerment is related to several preferable outcome

variables. In addition, research showed several preferable outcomes could be predicted by

affective commitment. From this research, some practical implications can be derived. The

relationship between empowerment and affective commitment is affected by job engagement

and trust in management. Whereas we could not find a direct relation with affective

commitment for each dimension of empowerment, significant effects are shown in

interactions with job engagement and trust in management.

This means that organizations must pay attention to the knowledge workers'

characteristics and the way the management presents itself to its employees in order to be

trusted by them. In short, it is not enough to „just empower your people‟, it would not

automatically lead to the commitment desired.

51

8.2.1 Putting it into practice

First, we will consider the main effects of meaning and self-determination. It is important to

communicate the organization‟s vision, goals and ideals to the employee. It might be wise to

do so during interviews already. Also during the employee‟s appointment attention should be

paid to these aspects. The second issue concerns the relation between self-determination and

affective commitment, the willingness to stay in the organization. It is important to listen to

your employee and to give him a certain degree of autonomy for decision-making. However,

this autonomy must fit in a certain framework, in which the employee can make decisions, but

stays attached to the directions and goals of the organization. Without this there is a risk of

losing affective commitment, which probably leads to alienation.

The second part of the practical implications is about the interactions with job

engagement and trust in management. In the case of an employee who is not feeling very

competent in doing his job, job engagement might be important to retain a certain degree of

affective commitment. Both the lowest and the highest degree of affective commitment are

related to an employee scoring low on the dimension competence. Thus, it is important to

monitor employees scoring low on competence. In the case of an employee feeling very

competent in his job, job engagement does not really influence the relation with affective

commitment. However, in this case trust in management plays an important role. The lowest

and the highest degree of affective commitment is related to an employee who feels

competent, depending on the degree in which the employee trusts the management of the

organization. In this case it is important to keep an eye on employees scoring high on

competence.

In the latter interaction, trust in management plays an important role in the relationship

with affective commitment. A high degree of trust in management also plays an important

role in the interaction with meaning and impact. Focusing on the dimension meaning, it is

important to pay attention to the employee who cannot identify his personal goals with the

ones of the organization. When, in addition, he does not trust the management of the

organization to a high degree, he will obviously score lower on the willingness to stay within

the organization. Finally, the importance of trust in management applies to the interaction

with impact. However, attention should be paid to the employee who has the feeling he can

influence the outcomes of the organization. That is, when this employee does not trust the

management, this will obviously result in a lower degree of affective commitment.

In short, it is important for organizations to ensure a culture of trust. In the article of

Clark and Payne (1997), literature about trust and the antecedents is discussed. According to

52

this article, the five facets of Butler and Cantrell (1984) encompass the main elements of trust

identified in literature. These five facets are integrity, competence, consistent behavior,

loyalty and openness. Based on this, it can be important for organizations to give substance to

these facets. For example by fulfilling promises, sharing values and information, and by

giving their employees a fair treatment.
