Objective: The present study was carried out in order to investigate sources of occupational stress in employees of welfare organization and relationship of these stressors with their job satisfaction. Among these stressors which are of two types of environmental and individual, sense of control (individual source), role conflict and role ambiguity (environmental source) were studied. In the next step, we studied the relationship of these stressors with employees' job satisfaction (in terms of nature of work, supervisor, colleagues, promotions, and salary).

Materials & Methods: The statistical population included all psychologists employed in rehabilitation organization. Out of them, 77 persons were selected through systematic random sampling (30%). The data of study were collected with job description index (Smith et al., 1969), occupational skill, knowledge questionnaire, and a checklist of measuring attitude toward occupational role.

Results: Results indicated that the stressors of role conflict and role ambiguity in employees are correlated with external locus of control. Positive attitude toward job role had a positive correlation with knowledge and diversity of occupational activity.  

Conclusion: The results revealed that the role conflict and role ambiguity affected by inefficiency of occupational skill and knowledge of employees are the major occupational stressors of employees and the sense of control had a regulating role in this regard.
