GENERAL CONCLUSIONS FROM THE GENERAL CONCLUSIONS FROM THE HAWTHORNE STUDIES:HAWTHORNE STUDIES:the amount of work a person does depends not so the amount of work a person does depends not so much on physical strength or dexterity, or even on much on physical strength or dexterity, or even on the physical conditions of work - it depends on the the physical conditions of work - it depends on the social conditions surrounding the worksocial conditions surrounding the work
