Job satisfaction, a worker's sense of achievement and success, is generally perceived to be directly linked to productivity as well as to personal wellbeing. Job satisfaction implies doing a job one enjoys, doing it well, and being suitably rewarded for one's efforts. Job satisfaction further implies enthusiasm and happiness with one's work. Hence the project entitled “A Study On Employee Job Satisfaction In Bharat Heavy Electricals Limited (BHEL), Tiruchirappalli” was undertaken to know the satisfaction level of the employees working in this Organization. The sample size of 150 employees was considered. The data were collected from the employees and analyzes were undergone. In addition to that necessary suggestions were also given.
