A survey was made among the employees of the Health Centre Novi Sad. It included 237 people, of which 99.6% were health workers and 0.4% administrative workers. Among the respondents 8.4% occupied a managing post. The questionnaire included the issues relating to the satisfaction of the employees with working conditions, work-associated fatigue, comparison of the job satisfaction five years ago and now, plans for the next five years, and overall job satisfaction. Based on the answers of the respondents it comes out that only 36.3% of the health workers are satisfied and very satisfied with their jobs, which is a very small percentage regarding the nature of the work they do. However, 42.2% of health workers plan to remain in the public sector in the next five years, and 41.8% do not even think about changing the job. This was logical to expect bearing in mind the material position of the health care and overall economic situation in the society.
