Specifically, it explores how distinct leadership attributes—namely visionary direction, decision-making effectiveness, communication skills, and adaptability—diversity Management. This study adopts a survey research design. Data was collected from 425 respondents, the data collected was analysed using multiple regression analysis. The results indicated that visionary direction has the highest standardized coefficient (Beta = .546, B = .544, p < .001), indicating its strong positive influence on Diversity Management. Decision-making effectiveness also demonstrates a significant positive impact (Beta = .214, B = .225, p < .001). In contrast, communication skills, and adaptability exhibit smaller effects (Beta = .087 and .056, respectively) with p-values of .058 and .175, suggesting that their contributions to the model are less pronounced and not statistically significant at the 0.05 level. Based on the findings, the study recommends that FIRS should implement structured Visionary Direction training programmes for supervisors, establish formal Decision Making Effectiveness frameworks that provide ongoing guidance and support to employees and should nevertheless invest in robust communication strategies.
