This study examined the relationship between Leader–Member Exchange (LMX), Organizational Citizenship Behavior (OCB), and Work Engagement among college teachers in Region XI. Using a convergent mixed-methods design, quantitative and qualitative data were collected and analyzed to determine the predictive power of LMX and OCB on teachers’ work engagement. Results revealed that higher-quality leader–member exchanges and strong organizational citizenship behaviors significantly predicted greater work engagement. The findings provide actionable insights for institutional policies and leadership strategies to enhance faculty performance and engagement in higher education.
