The Relationship Between Diverse Teams and Leadership Development Among Employees
Abstract
Workforce diversity is increasingly viewed as a strategic resource for organizations seeking to strengthen collaboration, learning, and leadership capability. This study examined the influence of gender, age, cultural, and educational diversity on leadership development among employees of Puma Energy (Malaysia) Sdn. Bhd., Pasir Gudang, Johor. Guided by Social Identity Theory, the study employed a quantitative cross-sectional design. Data were collected from 170 employees using a structured questionnaire measured on a five-point Likert scale and analyzed using IBM SPSS Version 29. Descriptive statistics, Cronbach’s alpha reliability analysis, normality assessment, Pearson correlation, and multiple regression were applied. All four diversity dimensions were positively and significantly correlated with leadership development: gender diversity (r = .733, p < .001), age diversity (r = .777, p < .001), cultural diversity (r = .810, p < .001), and educational diversity (r = .736, p < .001). The regression model was statistically significant, F(4,165) = 98.732, p < .001, and explained 70.5% of the variance in leadership development (R² = .705; adjusted R² = .698). After controlling for the other diversity dimensions, cultural diversity was the strongest significant predictor (β = .446, p < .001), followed by age diversity (β = .261, p = .005). Gender diversity (β = .063, p = .456) and educational diversity (β = .130, p = .100) were not significant predictors. The findings suggest that multicultural interaction and intergenerational collaboration may provide especially important developmental experiences for employees. Organizations can therefore strengthen leadership pipelines by creating structured opportunities for cross-cultural teamwork, intergenerational mentoring, knowledge sharing, and inclusive collaboration. Overall, the study provides context-specific evidence that diverse team experiences can support leadership capability when organizations intentionally facilitate inclusive interaction, mutual learning, and collaboration across employee differences.
