Job satisfaction is very important to health care organizations, since their duty is to provide public health. The current study aimed at evaluating the impact of demographic characteristics on job satisfaction among nurses. Methods: The current study was conducted on the job satisfaction survey of 120 nurses working in hospitals affiliated to Isfahan University of Medical Sciences, selected by systematic sampling. Data collection tools were job descriptive index (JDI) and demographic characteristics questionnaires. Data were analyzed with SPSS using comparison tests. Results: Average job satisfaction of nurses under the study was 112 ± 23.14. The highest and lowest levels of job satisfaction were related to co-nurses, and rights and benefits, respectively. Comparison tests showed a significant relationship between variables such as age, gender, marital status, education, work experience, and job satisfaction. Conclusions: The obtained results indicated that 60% of nurses were dissatisfied with their jobs. This is a very stressful job due to overload, dealing with mortality, the unpredictable nature of this job, lack of psychological support and the ambiguity of the authority/authorizations; therefore, job satisfaction of nurses should be seriously considered by the managers, especially the nurses that have lower levels of job satisfaction.
