Employees expect respect from their co-workers and supervisors and guarantee of job security which is appropriate for their efforts in the workplace. Also, those with overcommitment to work need to be more supported. A set of these variables are included in the effort-reward imbalance model. The objectives of this study were to assess validity of the ERI model and its effects on fatigue, emotional exhaustion, physical health and psychosomatic complaints. To test validity of ERI model, a sample of 235 personnel of an industrial company in Isfahan, Iran, was selected. To measure predictor variables, ERI questionnaire (Zurlo, Pes & Siegrist, 2010) was used. To measure criterion variables Including fatigue, emotional exhaustion, physical health and psychosomatic complaints, fatigue scale (Chalder & et al,1993),emotional exhaustion scale(Malach,1998),Physical health scale (Hilderbrandt & et al, 1991) and psychosomatic complaints scale(Driken,1969) were used respectively.  Factor analysis of ERI scale elicit four subscale namely job security, respect, effort and overcommitment with favorable stability. The results showed that there was a positive relation between two subscales of respect and job security and criterion variables. There was also a negative relation between two subscales of effort and overcommitment and criterion variables. The results of this study can be of prime importance for the improvement of personnel’s health in the industrial environments.

Measurement tools of the study were organizational citizenship behavior questionnaire developed by Podsakoff et al (1990), Maslash Burnout Inventory (1981). Data was analyzed through hierarchical regression analysis.Findings indicated that there was significant negative relationship between the emotional exhaustion and organizational citizenship behavior. OCBI moderated relationship between the emotional exhaustion and organizational citizenship behavior (OCB).Namely, in high OCBI there was significant negative relationship between the emotional exhaustion and organizational citizenship behavior, but in low OCBI this relationship disappeared. Confronting the emotional exhaustion, the managers should support personnel, so that more resources could be invested on the performances by the personnel.
