Purpose: The current study’s main goal is to investigate the impact of job stress on deviant workplace behavior in Egyptian firms. More precisely, it analyzes common job stresses such as role conflict, work overload, and role ambiguity, as well as non-job-related stressors such as family-to-work conflict. The proposed model is based on general strain theory. Design/Methodology/Approach: Multiple regression analysis is utilized in this study to investigate the relationship between variables, and structural equation modeling is used to assess structural links between measured variables and estimate the significance and size of causal linkages between the variables. Finally, a statistical model’s goodness of fit is used to assess and characterize how well a set of observations fits. It summarizes the discrepancy between the observed values and the predicted values under the statistical model. Findings: Results of the study have found that job stress has no direct effect on deviant workplace behavior; however, job satisfaction directs the effect which means that when employees are stressed, their satisfaction may decrease and so their deviant behavior may increase. Research Limitations/Implications: Because of the research approach and sampling technique used, the research findings may be limited in their generalizability. As a result, researchers are encouraged to examine the presented assumptions further. Practical Consequences: The study discusses the implications for the development workplace environment as well as managing the balance of work and family obligations. Originality/Value: This report addresses an acknowledged need by investigating how deviant workplace behavior might be reduced.
