RESEARCH DESIGN AND EXECUTION OF THE STUDY
1.1 INTRODUCTION
Stress is a common problem and a burning issue in modern society. The effect of stress is a
deviation from the existing physical and psychological condition of human life. Stress is
regarded as an inevitable consequence of employee functionality. Hans Selye first
introduced the concept of stress in the field of life science in 1936. He defined stress as “the
force, pressure, or strain exerted upon a material, object or person which resist these
forces\and attempt to maintain its original state."
The word “stress” is derived from the Latin word “stringer”, meaning to draw tight. From
the viewpoint of Physical Sciences, the phenomena of stress are evident in all materials
when they are subjected to “force, pressure, strain or strong-front”. Every material-steel,
rock or wood has its own limit up to which it can withstand stress without being damaged.
Similarly human beings can tolerate certain level of stress. Stress is highly individualistic in
nature. Some people have high levels of stress tolerance and thrive very well in the face of
several stressors in the environment. In fact, some individuals will not perform well unless
they experience a level of stress which activates and energizes them to put forth their best
results. For every individual, there is an optimum level of stress under which he or she will
perform to full capacity. If the stress experience is below the optimum level, then the
individual gets bored, the motivational level of work reaches a low point and it results in
careless mistakes, forgetting to do things and thinking of things other than work during
working hours and also leads to absenteeism which may ultimately lead to turnover.
If on the other hand, stress experience is above the optimum level, it leads to too many
conflicts with the supervisor or leads to increase of errors, bad decisions and the individual
may experience insomnia, stomach problems, and psychosomatic illness. The present world
is fast changing and there are lots of pressures and demands at work. These pressures at
work lead to physical disorders. Stress refers to individual’s reaction to a disturbing factor in
the environment. It is an adaptive response to certain external factor or situation or what can
be called environmental stimuli as reflected in an opportunity, constraint, or demand the
outcome of which is uncertain but important.
In short, stress is a response to an external factor that results in physical, emotional,
behavioural deviations in a person. Stress is an all pervading modern phenomenon that takes
a heavy toll of human life. Different situations and circumstances in people personal life and
in their job produce stress. They can be divided into factors relating to organization and
factors related to person which include his experience and personality traits. Job related
factors are work overload, time pressures, poor quality of supervision, insecure political
climate, role conflict and ambiguity, difference between company values and employee
values. Person related factors are death of a spouse, or of a close friend, family problems,
change to a different line of work, prolonged illness in the family, change in social activities
and eating habits.
1.1.1 Occupational Stress
Occupational stress can be defined as the harmful physical and emotional responses that
occur when the requirements of the job do not match the capabilities, resources, or needs of
the worker.
Selye [1936] defines stress as “a dynamic activity wherein an individual is confronted with
an opportunity, constraint or demand”. The concept of occupational stress is often confused
with challenge, but these concepts are not the same. Challenge energizes workers
psychologically and physically, and it motivates workers to learn new skills and master their
occupations. When a challenge is met, workers feel relaxed and satisfied (NIOSH,1999).
Thus, challenge is an important ingredient for healthy and productive work. The importance
of challenge in people’s work lives is probably what people are referring to when they say a
little bit of stress is good. Occupational stress is that which derives specifically from
conditions in the work place. These may either cause stress initially or aggravate the stress
already present from other sources. In today’s typical workplace, stress is seen as becoming
increasingly more common. People appear to be working longer hours, taking on higher
level of responsibilities and exerting themselves even more strenuously to meet rising
expectations about occupational performance.
According to United States National Institute of Occupational Safety and Health, Cincinnati,
(1999), Job stress can be defined as “the harmful physical and emotional responses that
occur when the requirements of the job do not match the capabilities, resources, or needs of
the worker. Job stress can lead to poor health and even injury. According to a discussion
document presented by United Kingdom Health and Safety Commission, London, (1999),
“Stress is the reaction people have to when excessive pressures or other types of demand
placed on them”.
On the basis of experience and research, NIOSH favours the view that working condition
plays a primary role in causing Occupational stress. However, the role of individual factors
is not ignored. According to NIOSH view, exposure to stressful working conditions (called
Occupational stressors) can have a direct influence on worker safety and health.
1.1.2 Causes of occupational stress
Nearly everyone agrees that occupational stress results from the interaction between worker
and the conditions of work. Views differ, however, on the importance of worker
characteristics versus working conditions as the primary cause of occupational stress. These
differing viewpoints are important because they suggest different ways to prevent stress at
work. According to one school of thought, differences in individual characteristics such as
personality and coping style are more important in predicting whether certain occupational
conditions will result in stress. In other words, what is stressful for one person may not be a
problem for someone else. This viewpoint leads to prevention strategies that focus on
workers and the ways to help them cope with demanding occupational conditions. Although
the importance of individual differences cannot be ignored, scientific evidences suggest that
certain working conditions are stressful to most people. Such evidence argues for a greater
emphasis on working conditions as the key source of Occupational stress, and for
Occupational redesign as a primary prevention strategy.
The workplace is an important source of both demands and pressures causing stress and
structural and social resources to counteract stress. The workplace factors that have been
found to be associated with stress and health risks can be categorized as those to do with the
content of work and those to do with the social and organizational context of work.
These factors that are intrinsic to job include long hours, work overload, time pressure,
difficult or complex tasks, lack of breaks, lack of variety and poor work conditions (for
example, space, temperature, light). Under work or conflicting roles and boundaries can
cause stress. The possibilities for job development are important buffers against current
stress, with under promotion, lack of promotion, lack of training and job insecurity being
stressful. There are two other sources of stress or buffers against stress, relationship at work
and the organizational culture. Managers who are critical, demanding, unsupportive create
stress, whereas a positive social dimension of work and good team working reduces it
(Causes and Management of Stress at Work, Michie, 2002).
1.1.3 Symptoms of work-related stress
Defining a clear link between occupational causes, and the resulting symptoms is much
harder for a condition. Because many of the symptoms of stress are generalized such as
increased anxiety, or irritability, it is easy for them to be ascribed to a characteristic of the
worker, rather than to a condition of the work. However, there is a mounting scientific and
medical evidence that certain types of work and work organization do have a measurable
and verifiable impact on the health of workers.
The range of symptoms includes physical symptoms, mental health symptoms,
psychological symptoms, asthma, irritability, smoking, ulcers, depression, heavy drinking,
heart disease, anxiety, eating disorders, diabetes, burnout, increased sickness, thyroid
disorders and low self esteem.
Some degree of stress is a normal part of life and provides part of the stimulus to learn and
grow, without having an adverse effect on health. When stress is intense, continuous or
repeated, as is often the case with occupational stress, it can result in ill health
(Hazards,1994). The experience of stress can affect the way individual’s think, feel and
behave, and can also cause physiological changes. Many of the short and long term illnesses
caused by stress can be accounted for by the physiological changes that take place when the
body is placed under stress. From the documented evidence, it is clear that as far as work
life is concerned extreme stress is so aversive to employees that they will try to avoid it by
withdrawing psychologically (through disinterest or lack of involvement in the occupation).
Excessive stress can destroy the quality of life and also affect family life.
In jobs where work overload is the cause of stress, the workers find that they have to take
time off to deal with stress, only to return to work to find that the already unmanageable
workload has substantially increased in their absence, thereby increasing the source of stress
and fuelling a vicious cycle which may ultimately lead to a complete breakdown in health
(Selye,1976).
1.1.4 Impact of employee stress
Both physical and psychological stressors have a tremendous impact on not only the
employees' health, but also the organizations. Some of the impacts of employee stress are as
follows.
Absenteeism
One of the grave impacts of employee stress is absenteeism. Employees under stress do not
feel motivated to work and therefore take more number of leaves citing different reasons.
As more and more employees cite ill health as the reason, the cost would all be added to the
organization as medical reimbursements. Employees might be absent from work to use it as
a coping mechanism against stress. Frequent employee absenteeism not only costs millions
to the organizations, but it also affects the overall productivity.
Loss of Judgement
A stressed out employee loses focus on his work. Due to this, the employee misses out the
vital information signals leading to ineffective decision making. Further, various research
studies have proved that stress also slows down the thinking process. According to
researchers, the enzyme - endorphins released under stress, slow down the ability to think
and affect the ability of judgement in an individual.
Employee conflicts
Stress also might have an impact on the interpersonal relationships at workplace. A person
under stress tends to be easily irritated leading to troubled relationships with his colleagues.
Workplace Accidents
Stress results in poor concentration and pre-occupation of the mind leading to workplace
accidents. It is generally reported that in their drive to attain deadlines and accomplish tasks,
employees tend to ignore safety rules leading to accidents.
According to a research conducted by Workers’ Occupational Health Services conclude
workers under stress are thirty per cent more likely to be involved in accidents than those
experiencing low levels of stress. In addition to all the above mentioned problems,
organizations would also face high turnover rates of employees, high replacement costs, loss
of intellectual capital and increasing grievances. Many organizations have realized the
serious impacts of employee stress and have started taking steps to combat it. The
responsibility of making a workplace employee friendly and healthy lies with both with the
employer and the employees.
1.2 MODELS AND THEORIES OF OCCUPATIONAL STRESS
1.2.1 French, Caplan and Kahn’s Person – Environment Fit (PE-Fit) theory
French, Caplan, Kahn and their colleagues (French and Caplan, 1972; French et al., 1982;
French and Kahn, 1962; Kahn et al., 1964) subsequently incorporated Lewin’s concepts of
stress and strain in their Person – Environment Fit (PE-Fit) theory, which is widely accepted
as a major conceptual framework for research on occupational stress (Chemers et al., 1985;
Edwards and Cooper, 1990). In the context of this theoretical orientation, occupational
stress is defined in terms of job characteristics that pose a threat to the individual resulting
from a poor match between the abilities of the employee and the demands of the job (French
and Caplan, 1972). The workplace stress that occurs as a result of incompatible person–
environment fit produces psychological strain that may contribute to stress-related physical
disorders (French et al., 1982).
1.2.2 Stress at Work Model
Cooper and Marshall’s (1976; Marshall and Cooper, 1979) Stress at Work model is similar
to PE-Fit theory, but is more specific in identifying five major categories of job pressure and
lack of organizational support in the workplace that contribute to occupational stress: (1)
pressures intrinsic to the job; (2) the employee’s role in the organisation; (3) interpersonal
relationships at work; (4) limitations in career development; and (5) organizational structure
and climate.
1.2.3 Karasek’s Demand–Control Model
Karasek’s (1979) Demand–Control model focuses on interactions between the objective
demands of the work environment and the decision latitude of employees in meeting these
demands (Karasek and Theorell, 1990). According to this model, ‘the greatest risk to
physical and mental health from stress occurs to workers facing high psychological
workload demands or pressures combined with low control or decision latitude in meeting
those demands’. (Schnall, 1998, p. 1) The combination of high job demands with relatively
little control contributes to lowered productivity and a greater risk of health-related
problems (Theorell and Karasek, 1996). The Demand–Control model also recognizes the
beneficial effects of social support from supervisors and co-workers. (Karasek et al., 1982;
Schnall, 1998)
1.2.4 Lazarus’ Transactional Process Model
Lazarus’ (1966) Transactional Process model of psychological stress and coping
conceptualizes stress as a process that involves a complex transaction between a person and
her/his environment (Lazarus and Folkman, 1984). In applying this model to occupational
stress, Lazarus (1991) emphasizes the distinction between the sources of stress (‘stressors’)
in the workplace and the emotional reactions that are evoked when a particular stressor is
cognitively appraised as threatening. Three types of appraisal mediate the effects of
stressors on emotional reactions. Primary appraisal occurs when a stressor is evaluated in
terms of its immediate impact on a person’s wellbeing. Secondary appraisal takes into
account the resources of the employee for coping with the stressor.
The third type, reappraisal, incorporates new information resulting from the worker’s
appraisal of the effectiveness of her/his efforts to cope with a particular stressor.
1.2.5 National Institute for Occupational Safety and Health (NIOSH) Model
National Institute for Occupational Safety and Health (NIOSH) defines job stress in terms
of ‘the harmful physical and emotional responses that occur when the requirements of the
job do not match the capabilities, resources, or needs of the worker. (NIOSH, 2002) This
definition of job stress, as well as the resulting model developed by NIOSH, was primarily
influenced by PE-Fit theory. The NIOSH model explicitly recognizes that exposure to
stressful working condition plays a primary role in causing job stress and influencing
worker safety and health, while ‘individual and other situational factors can intervene to
strengthen or weaken this influence’. However, the NIOSH model gives little attention to
the significant influence of the employee’s cognitive appraisal of sources of stress in the
workplace.
1.2.6 Spielberger’s State–Trait Process (STP) Model
Spielberger’s State–Trait Process (STP) model of occupational stress focuses on the
perceived severity and frequency of occurrence of two major categories of stressor events,
job pressures and lack of support. (Spielberger et al., 2002) The STP model builds on the
PE-Fit and Transactional Process models by endeavouring to integrate these models with the
conception of anxiety, anger and depression as emotional states and personality traits
(Spielberger, 1972; Spielberger et al., 1983; Spielberger et al., 1988). The STP model gives
greater emphasis than other models to the effects of individual differences in personality
traits in determining how workplace stressors are perceived and appraised.
1.3 JOB STRESS, JOB SATISFACTION AND WELLBEING
During the last 25 years various research studies of job stress have provided substantial
evidence supporting the notion that exposure to work stressors has a negative impact on a
worker’s mental and physical health and job satisfaction (Ganster and Schaubroeck, 1991).
Other research findings report some evidence of work stress leading to higher health care
costs, more insurance claims, higher rates of absenteeism (Gupta & Beehr, 1979; Spector,
Dwyer, & Jex, 1988), greater turnover (Gupta & Beehr, 1979), and decreased job
performance (e.g., Motowidlow, Packard, and Manning, 1986; Spector et al., 1988).
Compared with the outcome variables that deal with employees’ mental and physical
wellbeing, however, there has been less attention given to the effect that job stressors have
on work performance (e.g., see Beehr, 1995; Jex, 1998 for reviews). The relationship
between work stress and job performance has been neglected primarily because job
performance is a rather complex, multi dimensional variable that is often difficult to
measure accurately. More specifically, there is often low variability in performance
criterion measures due to a substantial amount of error in ratings. In essence, even though
employees may actually perform at different levels, they often receive similar performance
evaluations. Thus, the effect that stressors have on performance outcomes may appear
weaker than it actually is. Furthermore, it is difficult to obtain multiple measures of
performance that include more objective indicators (Beehr, Jex, Stacy & Murray, 2000).
As a result, researchers have focused more on outcomes that supposedly affect the
functioning of the individual worker’s performance (e.g. substance abuse, mood states,
depression, various health indicators) rather than on performance outcomes themselves.
It is generally assumed that the form of the stressor – performance relationship is linear.
However, because stressors may increase physiological arousal (e.g., see Fox, Dwyer &
Ganster, 1993; Ganster & Schaubroeck, 1991), the relationship between an individual’s
physiological reactivity and performance may take the form of an inverted U-shaped
function as originally described by the Yerkes-Dodson Law (Yerkes and Dodson, 1908).
Recently, Xie and Johns (1995) found nonlinear, U-shaped effects in a study in which they
examined the relationship between job complexity and mental health problems. Despite this
finding, the vast majority of occupational stress studies assume linear relationships.
1.4 STATEMENT OF THE PROBLEM
Today workplace stress is becoming a major issue and a matter of concern for the
employees and the organizations. It has become a part of life for the employees, as life
today has become so complex at home as well as outside that it is impossible to avoid stress.
Occupational stress arises due to lack of person- work environment fit. When occupational
stress is mismanaged, it affects the human potential in the organization. It further leads to
reduced quality, productivity, health as well as wellbeing and morale.
At workplace, stress related to the role performed by the employee in the organization is one
of the important determinants of successful adjustment and subsequent performance of an
employee. The stress induced due to roles performed by individuals as employees has been
a potent organizational stressor. (Kahn et al., 1964; Srivastava, 2007) Its outcomes have
been found to be costly to the organization. (Fisher and Gitelson, 1983)
One of the pioneers of research on organizational role stress, Pareek (1993) has reiterated
that the performance of a role in an organization has built in potential for conflict due to
which stress may start rearing its head. Such stress can contribute to various dysfunctional
outcomes for the organization like job related tensions, job dissatisfaction and lower
performance (Behrman and Perreault, 1984; Singh, 1992; Shahu & Gole, 2008).
Occupational stress can be inadvertently linked to success or failure at one’s job. The
general impression about occupational stress is the feeling of failure due to work overload.
But if this is the case and so simple a problem then merely by reducing the amount of work,
occupational stress could have been done away with. Stress is a part of everyone’s daily
life. It means that the person cannot cope with the demands put forward by his or her work,
which is opposite to their expectations of rewards and success. It affects both the person
concerned and the relationships he or she forms in the society be it with family or friends.
In this present era of cutthroat competition, the idea of being perfect becomes very
necessary to strive and become successful. The worker has to be perfect in his job or else he
will be replaced or at least lag behind in his work leading to stress. In India, the problem of
stress management is gaining more and more importance due to the new privatized nature of
the economy.
People are leaving behind the cozy atmosphere of government jobs and joining the private
sector where there is no end to the amount of work that a person can undertake. In this
environment coping with stress becomes very important. One has to be aware of the
problem well in advance to be able to deal with it.
During the past decade, the banking industry had undergone rapid and striking changes like
policy changes due to globalization and liberalization, increased competition due to the
mushrooming of more private sector banks and the introduction of new technologies. Owing
to these changes, the employees in the banking industry, particularly public sector bank
employees are experiencing a high level stress. The advent of technological revolution in all
occupations coupled with globalization, privatization policies has drastically changed
conventional patterns in all sectors. The banking industry is no exception to this changing
phenomenon.
Existing literature reveals that more than sixty per cent of the public sector employees have
one or more problem directly or indirectly related to these drastic changes. Along with other
sectors, the banking industry is also leaning towards the policy of outsourcing and
compulsive rewarding option of voluntary retirement scheme. All these factors are
prospective attributes to cause occupational stress and related disorders among the
employees. Although many studies have been conducted on the psycho social side of the
new policy regime in many sectors, there are only few studies, as far as the banking sector is
concerned, while the same sector has been drastically influenced by the new policies.
The elevated stress levels of employees in banking industry are associated with increased
absenteeism, sickness, reduced productivity, job dissatisfaction and low morale. In such
circumstances, efforts to sustain a high level of work performance over time can be a
tedious task for organizations as well as for employees.
Considering occupational stress as a debilitating syndrome, this study has been undertaken
with an aim to systematically investigate the factors causing occupational stress amongst
public sector bank employees. Banks are among the top ten high stress workplaces in India.
Elucidating the causes of occupational stress and its impact on job satisfaction is important
not only for its potential implications for stress management at banks but also for enhancing
an understanding of strategic human resource management. With this aim, the study makes
an effort to identify the sources of occupational stress experienced by the employees of
public sector banks.
At this juncture, the present study is undertaken to address the specific problems of bank
employees related to occupational stress and job satisfaction. This throws light into the
pathogenesis of various problems related to occupational stress and its impact on job
satisfaction among public sector bank employees in Thiruvarur district of Tamilnadu.
1.5 SCOPE OF THE STUDY
The occupational stress adversely affects the health, performance and job satisfaction of the
employees of an organization. Workers who are stressed are also more likely to be
unhealthy, poorly motivated, less productive and less safe at work. Their organizations are
less likely to be successful in a competitive market. Stress can be brought about by
pressures at home and at work.
Employers cannot usually protect workers from stress arising outside work, but they can
protect them from stress that arises through work. Stress at work can be a real problem to
the organization as well as for its workers. Good management and good work organization
are the best forms of stress prevention.
In general, occupational stress determines the level of job satisfaction, which in turn affects
the wellbeing of employees. Hence, this study throws light on the pathogenesis of various
problems related to occupational stress experienced by the public sector bank employees.
The study is helpful in assessing the extent of stress experienced and its effect on the job
satisfaction of the employees in the public sector banks. This study will also be helpful to
draw up further policy on related fields and act as a secondary data for further research.

1.9 METHODOLOGY
1.9.1 Research Design
The present study is exploratory as well as descriptive in nature in context of public sector
banks. Here the researcher on the one hand, has attempted to lay down the theoretical
ground for occupational stress and tried to explore its theories, models and various studies
related to it. On the other hand the researcher has tried to describe the level of occupational
stress and job satisfaction of bank employees through the scale called OSI (Occupational
Stress Index).
1.9.2 Area of the study
The study was conducted in Thiruvarur district of Tamilnadu. Thiruvarur district is one of
the 32 districts in the Tamilnadu state of India. The district occupies an area of 2161 km². It
lies between Nagapattinam district on the east and Thanjavur district on the west, and is
bounded by the Palk Strait on the south. The district headquarters is Thiruvarur town. The
district has a population of 1,268,094 (as of 2011). It is 20.29% urbanized. It has a literacy
of 76.90%, slightly higher than the state average.
The Thiruvarur district, along with the Nagapattinam district was part of the Thanjavur
district before 1991. After that, the present Taluks of Thiruvarur district and Nagapattinam
district were separated from Thanjavur district, and formed the Nagapattinam district. The
present Thiruvarur district was formed in 1997 by trifurcating the then Thanjavur district.
Thiruvarur district is made up of 7 Taluks namely Kudavasal, Mannargudi, Nannilam,
Needamangalam, Thiruthuraipoondi, Thiruvarur and Valangaiman. Due to potential growth,
more number of public and private sector banks have established their branches in this
district and there is intense competition between public and private sector banks to tap the
rural market. Hence, this district is purposively selected by the researcher to analyse the
occupational stress and job satisfaction of the public sector employees.
1.9.3 Population
The population of the study constitutes public sector bank employees in the Thiruvarur
district of Tamilnadu. The population includes officers, clerks and sub staff working in the
selected public sector banks.
1.9.4 Sample size determination
For the purpose of the analysis, the employees are classified as officers, clerical staff and
sub staff. The branch managers and field officers and cash officers are considered as
officers, clerks and recovery marketing officers are considered clerks and messengers,
sweepers and watchmen are viewed as sub staff. Among the public sector banks functioning
in Tiruvarur district, Indian Overseas bank, Indian bank and State bank of India play a
prominent role.
Therefore, Indian Overseas Bank, Indian Bank and State Bank of India are selected for the
study. They have established 20, 19 and 18 branches respectively in the district, ten
branches from each bank are purposively selected for the study. There are 855 employees
working in Indian Overseas Bank, Indian Bank and State Bank of India in the selected
branches, of which 177 are officers, 444 are clerks and 234 are sub staff. The sample size
was calculated to guarantee a sufficient number of respondents in each branch of the bank.
Thus, the following formula has been used to estimate the population sample size (The
Survey System, 2007):
t² * p * (1-p) Minimum Sample Size (n) = −−−−−−−−−−−
m² Where:
n = required sample size (minimum size) t = Confidence level at 95% (standard value of 1.96) p = Estimated fractional population of subgroup, expressed as
decimal (0.5 used for sample size needed) m = Margin of error at 5% (standard value of 0.05)
n = 1.962 x 0.5 x (1-0.5) ∕ 0.052 = 384
Correction for Finite Population
SS New SS = -----------------
SS-1 1 + --------- Pop
Where: pop = population
SS = Sample size
384New SS = ------- = 265
384-1 1 + --------
855
As per the formula the required total sample size is 265, which constitutes 31 per cent of the
total population. Therefore, 31 per cent from each category is drawn on the basis of
stratified random sampling method. The universe and sample size is given below.

1.9.5 Required data set
In order to achieve the objectives of this research, data were collected both from the primary
and secondary sources. The primary data were collected from the respondents through a
structured questionnaire. A well developed and widely used Occupational Stress Index
(OSI) in the Indian context (Srivastava and Singh, 1981) was chosen to assess the
occupational stress of the sample. The questionnaire consisted of 48 statements with five
alternative responses e.g., 5 scores for absolutely true, 4 for almost true, 3 for partially true,
2 for almost false and 1 for absolutely false. The statement with asterisk should be scored
inversely, e.g., 5 for absolutely false and 1 for absolutely true.
Job Descriptive Index developed by Smith and Kendal (1966), was used to assess the job
satisfaction of the sample. The job descriptive index contains a series of statements for each
of these five areas and the individuals were asked to mark “Yes” (Y) or “No” (N) or
doubtful (?) related to job. Positive statements get a score of 2 for yes, 1 for doubtful and 0
for No. Negative statements get 2 for No, 1 for doubtful and 0 for yes. Only the total score
obtained for the five areas was considered as a measure of job satisfaction. High score
indicates high job satisfaction.
Subjective wellbeing inventory (SWBI) by Nag Pal and Sell (1984) was used for gauging
the subjectively perceived mental and physical health status of employees. Wellbeing was
used as one of the constituent factors in the measurement of success of the organization.
The subjective wellbeing is scored by attributing the values 3, 2, 1 to response categories of
the positive items and 1, 2 and 3 to the negative items. The minimum and maximum scores
that can thus be obtained are 40 and 120 respectively.
The total score can be interpreted summarily in the light of three broad score ranges: 40 –
60, 61 – 80 and 81-120 to have an overall picture of wellbeing status. If the respondents
secure the mean score between 40 and 60 their status of wellbeing is low, the mean score
between 61 and 80 indicates the moderate status of wellbeing and the mean score between
81 and 120 expresses higher status of wellbeing.
The secondary data have been collected from the sources like books related to stress
management, previous research studies, national and international journals and online
journals.
1.9.6. Statistical Analysis
Descriptive and inferential techniques such as cross tabulations, chi-square test, correlation,
and t-test were used for the analysis of data and testing the hypotheses in accordance with
the objectives.
1.9.7 Pilot study
Before the field survey was conducted, the consistency of the information has become
essential and a pilot survey was conducted for this purpose. In this study, widely used
structured questionnaires were used. So, the validation of the questionnaire is not required.
The researcher also has conducted a pilot study, for which the standardized questionnaire
was supplied to 25 respondents and this was tested for extracting the tentative results. The
results of the pilot study indicate that the respondents have experienced stress to a certain
extent, which induced the researcher to conduct the full fledged research on this topic.
1.9.8 Period of the study
The study was conducted from 2009 to 2012.
1.10 CONCEPTUAL DEFINITIONS
1.10.1 Stress
In medical terms, stress is described as, "a physical or psychological stimulus that can
produce mental tension or physiological reactions that may lead to illness."
Stress is defined as "the result produced when a structure, system or organism is acted upon
by forces that disrupt equilibrium or produce strain"1.
Hans Selye is one of the founding fathers of stress research. In his view, (1956) stress is not
necessarily something bad – it all depends on how you take it. The stress of exhilarating,
creative successful work is beneficial, while that of failure, humiliation or infection is
detrimental. Selye believed that the biochemical effects of stress would be experienced
irrespective of whether the situation was positive or negative. According to Shanmugham
(1981) stress is any condition that strains the coping capacities of the person.
1.10.2 Occupational stress
Beehr and Newman (1978) define occupational stress as "A condition arising from the
interaction of people and their jobs and characterised by changes within people that force
them to deviate from their normal functioning."
The occupational stress refers to "the harmful physical and emotional responses that occur
when the requirements of the job do not match the capabilities, resources, or needs of the
worker. Job stress can lead to poor health and even injury"2
It simply means that workplace stress generally arises when there is a mismatch between the
1 Taber's Cyclopedic Medical Dictionary2 United States National Institute of Occupational Safety and Health, Cincinnati, 1999
nature or magnitude of the job to be done and the employee’s desires and capabilities.
Further, the definition also categorizes workplace stress into physical stress and
psychological or emotional stress.
1.10.3 Perceived stress
Perceived stress refers to an individual’s perceived response to interaction with his or her
social environment.3
1.10.4 Job satisfaction
The Harvard Professional Group (1998) sees job satisfaction as the key radiant that leads to
recognition, income, promotion, and the achievement of other goals which ultimately leads
to a general feeling of fulfillment. Job satisfaction has been defined as a pleasurable
emotional state resulting from the appraisal of one’s job.4
1.10.5 Subjective wellbeing
"Wellbeing has been defined by individual characteristics of an inherently positive state
(happiness). It has also been defined as a continuum from positive to negative, such as how
one might measure self-esteem. Wellbeing can also be defined in terms of one's context
(standard of living), absence of wellbeing (depression), or in a collective manner (shared
understanding)." 5
Subjective wellbeing can be simply defined as the individual’s current evaluation of
happiness. Such an evaluation is often expressed in affective terms; when asked about

subjective wellbeing, participants will often say, I feel good” Subjective wellbeing is thus, at
least in part, a proxy for a global affective evaluation.6
1.11 LIMITATIONS OF THE STUDY
The research study has the following limitations:
The study is carried out in selected public sector banks, i.e. Indian Bank and State Bank of
India in Tiruvarur District of Tamilnadu. Thus, its findings cannot be generalized for other
public sector banks and private sector banks.
In the study, the researcher has not developed any scale. Instead readily available structured
and standardized scales are used as these are widely and universally accepted for measuring
occupational stress and job satisfaction.
The study is purely based on the respondents’ opinion. The researcher felt that the
respondents might express biased opinions which limit the validity of the study.
Individuals’ stress susceptibility varies over time. The environment can also vary in its
conditions. Since stress is a complex and dynamic process presented in different areas of
life, this research focuses only on the stress at work place due to occupational stress. In this
study an attempt to identify basic stress management strategies is applied to public sector
bank employees in a work situation. However, this approach restricts the findings to a
specific kind of experience in the given work environment.
Respondents’ opinion may change from time to time and the responses are also subject to
variations depending upon the situation and attitude of the respondents at the time of the
survey. In this study, occupational stress experienced by the employees, is alone considered
and the perceived stress (arising from outside the working place) is not taken into account.
6 Schwartz & Strack, 1999.
In this study, primary data were collected only from the permanent workers, the opinion of
the temporary, causal and contract workers was not taken into account.
In this research, the researcher has mainly focused on occupational stress, and the level of
job satisfaction of the employees in the study unit. The impact of stress on work related
behaviour of employees, such as absenteeism, loss of judgment, employee conflicts and
work place accidents is not analyzed in this study. It is directed for future research.
