Background: Mental disorders have an important relationship with work conditions. Excessive workload, laborers needs and expectations ignorance, harmful physical agents, noise, poor lightning and bad work atmosphere result increasing stress and job dissatisfaction in workers.
Methods: This descriptive-analytical survey implemented in order to investigate stress and job satisfaction rate of one of the Hamadan's factories laborers and its relationship with physical factors of work environment in 2001. Research population was the laborers of the old and new injection units (IS) of the factory. Data gathering tools were questioners, checklists and tools for measuring physical factors of work environment which all have been calibrated regarding to reliability and validity. Data analysis was performed using t-test, Chi-Square, and multiple regression.
Results: Findings showed that stress scores in both the old and new IS units were considerable. T-test showed a significant difference in the mean scores of stress (P < 0.05) and job satisfaction (P < 0.01) so that stress was higher in old IS unit and job satisfaction was higher in new IS unit. After measuring harmful physical factors in work environment it was revealed that Tergoison heat indicator (WBGT) in old IS unit was higher than new one (30.2 versus 24.7), adversely balanced sound pressure and light in new IS unit were higher than old one (96.27 to 94.74 and 57.2 to 37.62). Multiple regression analysis showed a significant relationship among stress components (pH physical condition) and job satisfaction.
Conclusion: Findings of this survey showed that increasing of harmful physical factors in work environment leads increasing job stress and decreasing job satisfaction among laborers.
