Data of 413 participants was 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.
