The purpose of the paper is to study employee turnover intentions using the organization’s perceived diversity climate. The study looks at the moderating effect of perceived ethical climate and the mediating effect of affective commitment on the link between the variables identified. Responses from 312 employees are included in the study’s empirical data. The software SMART PLS 4.0 was used to do the analysis. The study discovers that the diverse atmosphere is a precursor of the turnover intention, which frequently predicts future employee voluntary turnover. Additionally, the mediating impact of affective commitment helps to explain this link. The study also identifies ethical climate as a moderator, strengthening this association. This research adds value by investigating the affective commitment as a mediator in the link between diversity, climate, and employees’ turnover intention, and it may be the first to investigate the moderating influence of ethical climate given the importance of retention to the organisation. These results highlight the value of informing employees about the multicultural and ethical cultures at work.
