This research examines the relationships among Corporate Governance, Internal Control, Corporate Reputation, and Employee Engagement, with particular attention to how leadership styles influence these dynamics. The findings reveal that strong governance practices, robust internal controls, and a positive corporate reputation all contribute to higher levels of employee engagement. Moreover, the study identifies that leadership style significantly shapes these relationships. Specifically, democratic leadership enhances the impact of organizational mechanisms on engagement, while bureaucratic and laissez-faire leadership selectively influence the effects of internal controls and reputation. Authoritarian leadership, on the other hand, plays a decisive role in strengthening the link between governance, internal controls, and engagement. These results underscore the importance of tailoring leadership approaches to maximize the effectiveness of organizational practices in fostering employee engagement. The study provides actionable insights for both scholars and practitioners seeking to improve workforce motivation and organizational performance.
