Effort-Reward Imbalance (ERI) model is one of the methods for studying occupational stress in the workplaces. Considering there has been no comprehensive study on the determining of effective individual and organizational parameters in Iran, the aim of this survey was to detect the parameters affecting perception of ERI in workers in the workplaces in Iran.

ERI is reported in almost 50% of workers. After eliminating confounders, the logistic regression model indicated that parameters like education level (OR= 1.507, P= 0.033), having exercise (OR= 0.375, P= 0.034) and having right for choosing work-rest schedule (OR= 1.878, P= 0.002) as promoters and parameters like having second job (OR=2.069, P=0.008), perception of co-worker shortage (OR= 2.415, P According to the results of this study it can be mentioned that if intervention is requisite for improving Effort-Reward situation, parameters like education level, having exercise and having right for choosing work-rest schedule, having second job, perception of co-worker shortage and having shift work system for work should be adjusted.
