Introduction: While great efforts have been made to determine the quality of life in hospital staffs, few studies have been conducted to identify the effective factors on the quality of life of these employees. The purpose of the present study was to investigate the relationship between workload and quality of life in hospital personnel.

Material and Methods: In this descriptive-analytical study, 200 staffs were selected randomly from two large hospitals of Tehran University of medical sciences (Imam Khomeini and Shariati hospitals). The data collecting tools were three questionnaires including demographic characteristics, quality of life (SF-36), and NASA-TLX workload. SPSS software (version 18.0) was used to analyze the data by descriptive statistics, and Pearson and Spearman correlation tests.

Results: Based on the findings of the study, the mean total scores of the quality of life and the workload were 50±18 and 69.7±13.9, respectively. The results revealed significant reduction in all dimensions of quality of life in nurses compared with laboratory and operating room staffs. Meanwhile the nurses’ workload scores were higher than the two aforementioned groups (p = 0.001). Moreover, there was a significant inverse relationship between workload and quality of life in hospital staffs (P=0.004, r = -.306).
