Background Work ethics has a significant effect on the individual and group activities, performance and organizational results. This study examines the interactive role of job engagement and job propriety with work ethics and intent to leave of the employees. Method This study is descriptive-correlation research. Statistical population included all 368 employees of state universities of Tabriz. Using Cochran formula (d = 0. 5, p= 0. 5) and stratified random sampling, the sample size of 350 people was obtained. To gather data, standard questionnaires were used. Using Cranach Alpha, the reliability of job engagement (0. 75), job propriety (0. 87), work ethics (0. 70), and intent to leave (0. 84) was calculated. Obtained data were analyzed by correlation method and modified stepwise regression. Results Results showed a positive and significant correlation between two variables of job engagement and job propriety and work ethics (p=0. 001, r=0. 16, r=0. 25). Also, there is a negative and significant correlation between two variables of job engagement, job propriety and intent to leave (p=0. 001, r=-0. 28, r=-0. 32). Moreover, interacting together, job engagement and job propriety predict work ethics and intent to leave. Conclusion Results showed in every organization, interest in work, job engagement and job propriety with employees improves their work ethics and organization as well. Thus, intent to leave of the employees decreases and the organization should pay a specific attention to them.
