Purpose The purpose of this study is to examine the relationship between diversity climate and tacit knowledge sharing and the mediating role of workplace belongingness between them. Design/methodology/approach The sample for this study consists of 495 employees (52.1% male, n = 258) drawn from varied occupational groups. Data were collected online using existing self-report measures. Hypotheses were tested with ordinary least squares regression-based path analysis. Findings This study provides evidence that diversity climate is positively related to workplace belongingness and tacit knowledge sharing. Furthermore, workplace belongingness is positively related to tacit knowledge sharing. Finally, workplace belongingness mediates the relationship between diversity climate and tacit knowledge sharing. Practical implications The findings highlight the need for organizations to promote fair human resource (HR) policies and practices by enacting and judiciously implementing policies that promote inclusiveness and fair treatment to stand a chance of benefiting from employees’ tacit knowledge sharing. Originality/value This study builds on existing research but shifts the focus to the influence of diversity climate on tacit knowledge sharing and thus sets up a precedent for subsequent research in this area. This study is, therefore, the first to attempt to link diversity climate to tacit knowledge sharing through workplace belongingness.
