This study explored the impact of participatory management practices in schools, focusing on the experiences of teachers regarding their school heads' leadership styles. Participatory management, characterized by empowerment, shared decision-making, and stakeholder collaboration, had gained prominence as an effective approach to enhancing organizational effectiveness and fostering stronger relationships between employees and employers. However, challenges persisted in the true implementation of these practices, particularly in educational settings where school heads often failed to involve teachers in key decision-making processes. This research addressed the gap in understanding the influence of participatory management on teachers' behavior, morale, and overall effectiveness. Conducted in Cotabato Province, Philippines, the study employed a phenomenological research design, interviewing 15 teachers to gather insights into their lived experiences. The findings revealed three key themes: Teacher Empowerment, Shared Decision-Making, and Encouraging Stakeholder Collaboration, which highlighted the positive effects of participatory management on teachers' confidence, professional growth, and their active involvement in school improvement initiatives. The study emphasized the importance of inclusive leadership and collaborative decision-making in fostering a thriving educational environment.
