Objective: Rehabilitation services employees are exposed to stressors at everyday work because they are in touch with people who disability and problems have associated with. Inappropriate policies and processes in work place aggravate stress and would adversely affect mental and physical health of this population which in turn would affect their quality of work.

Materials & Methods: In order to determine the status of inappropriate organizational policies and processes as organizational stressors and related stress intensities in Tehran’s comprehensive rehabilitation centers, in a descriptive study all of the personnel were asked to fill a questionnaire which consisted of 32 questions. Content validity was approved by expertise people and reliability was 0.83.

Results: Revealed that misevaluation of employees (%98) and using unclear and inappropriate criteria for evaluating personal (%95) were the most prevalent inappropriate organizational policy and process that personnel confronted with. Also we found that exposure to "inequality of payment for similar jobs" and "invalidity of criteria which were used for personnel evaluation", induced highest degree of stress on employees (2.64 from 4 & 1.71from 4 respectively).

Conclusions: We conclude that as the most prevalent factor which induced stress in personnel is misevaluation, correction of personnel evaluation system should be over emphasized.
