Background & Objective: Job satisfaction is the person's attitude toward his/her work. Increasing nurses' job satisfaction result in better quality of nursing care and reduces the number of nurses who leave their job. Conditions of different wards of hospitals can affect nurses' job satisfaction. The aim of this study is to compare nurses' job satisfaction in oncology and delivery wards.

Methods & Materials: This is a cross-sectional comparative study. A total of 144 nurses (94 nurses in oncology and 50 nurses in delivery wards) of Tehran University of Medical Sciences hospitals participated in the study. Data were collected using a questionnaire. Data were analyzed using descriptive and inferential statistical test (chi-square).

Results: Comparison of the global job satisfaction among oncology and delivery nurses, indicated that there was no statistical significant relationship between them from working in a specific ward point of view (P=0.637). Also there was no significant relationship between intrinsic job satisfaction and working in a specific ward (P=0.966). There was statistical significant relationship between extrinsic job satisfaction and working in specific ward (P=0.039).

Conclusion: Considering that extrinsic job satisfaction of oncology nurses were low, reconsideration about specific conditions of oncology wards and taking efficient measures in improving nurses' extrinsic job satisfaction (especially oncology nurses) is essential.
