Behaviors of employees constitute focal point of a number of scientific studies conducted about organization behavior and the thought that such behaviors are affected from the satisfactions of employees that they get from their jobs and that they feel from their lives comes to the fore. Because of this, “Job and life satisfaction” come up as two issues having a high degree of importance among organizational behavior issues. In this context, in the study conducted; it was researched how much job characteristics which are a critical factor in business life affect satisfactions that they get from their jobs and their life satisfactions. Within the scope of this, 5 main Job characteristics (diversity, integrity, independence and feedback conditions of skills) determined with job diagnostic survey developed by Hackman and Oldham (1974) were used in this research which was conducted on 585 people who work in institutions which are active in government private sector. According to findings obtained, it was determined that job characteristics have more effect on job satisfaction than life satisfaction. It was found that whereas integrity of job in job characteristics in life satisfactions of employee is effective on life satisfactions of employees, other four job characteristics in life satisfaction are effective on job satisfaction. In addition to this, it was examined whether perceptions towards characteristics of the jobs employees perform change according to some demographic factors (sex, age and marital status) within the scope of this.
