The purpose of this research article is to study the effect of inclusion and perceived organizational diversity on turnover intention with the mediating role of employee engagement. Data of 413 participants were evaluated for this study, wherein the participants included IT professionals working in India. PLS-SEM was used to the test the hypotheses of the study by developing a path model and carrying out measurement and structural model assessment. The results revealed that inclusion, perceived organizational diversity, and employee engagement exhibit significant negative effect on turnover intention and are strongly able to predict turnover intention of the IT professionals. In addition, employee engagement partially mediates the relationship of inclusion and perceived organizational diversity with turnover intention. Overall, the study highlights that when employees feel included in the organization and there is a positive perception on diversity management, it leads to enhanced employee engagement and a lowered turnover intention.
