Discussion
The present study developed and tested a causal model which investigated the effect of some important factors on the employees’ productivity and effectiveness. Specifically, it investigated the effect of emotional intelligence, occupational stress, and job satisfaction on organizational commitment in one of the major organizations in Iran. In the model proposed by most of the researchers data were analyzed through Path Analysis method. In this study, data were collected using direct observation and non-purposeful interviews. In addition to the causal model, the effects of factors on each other were also studied. Contrary to the previous empirical findings and commonly held beliefs, the findings of this study show that emotional intelligence does not have any direct and indirect effects on occupational stress, job satisfaction, and organizational commitment. Moreover, the results of the path analysis revealed that occupational stress had a significant negative impact on the job satisfaction of the sampled employees, and job satisfaction positively influenced organizational commitment. It was also found that only occupational stress had an indirect negative effect on organizational commitment through job satisfaction.
