This study aims to investigate the mediating role of self-efficacy on the relationship between work stressors and CWB. The valid respondents were 304(n=304) which were selected based on simple random, stratified, and judgmental sampling techniques taking structured questionnaire as data collection tool. To analyze the data; descriptive statistics, correlation analysis, mediation with multiple regression and SEM with path analyses were applied. Causal- approach (Baron and Kenny‟s approach), normality theory method and bootstrap re-sampling techniques were used to test the significance the mediation (indirect) effect. The result shows that work stressors were very important (especially organizational constraints and justice) predictors of CWB. But self-efficacy was affected only by organizational justice and workload with negative insignificant relation with CWB. The result also suggests there is no mediation. To control counterproductive work behavior, organizations (particularly CBE) need to be aware and minimize work stressors to safeguard itself and its employees.enCounterproductive work behavior, work stressorsThesis
