Abstract
This qualitative multiple case study explored how micro politics in school management affect the
practice of teacher leadership in the context of Nigerian public secondary schools. It shows the extent
by which the practice of micro politics in public secondary schools affects the promotion of teacher
leadership. Participants included nine teachers, three principals, vice-principals and an educational
administrator in an Educational District in Lagos, Nigeria. Data for the study was generated through
semi-structured interviews and documentary analysis. The study reveals that micro politics is part of
human existence and it leads to forming of cliques, which affects professionalism in organisations. It
also reinforces the role principals play in traditional models of leadership, which affects teaching and
learning processes. The study recommends adherence to ethical standards in schools and that the
era of principal as a sole leader in school leadership is over. The study contributes to better
understanding of leadership development in schools.
