Some secondary school principals are complaining about teachers' reluctance to participate in any activities beyond classroom teaching. To understand this phenomenon, the study attempts to explore the inhibiting factors that hinder teachers in selected secondary schools in the Maseru district from supporting and engaging in teacher leadership (TL) activities. This qualitative inquiry is underpinned by the critical theory (CT), which among others aims at revealing the core factors that contributed to teachers' lack of enthusiasm in performing various TL related activities. Also, to suggest strategies that could pioneer a change in teachers' attitudes towards participation in school leadership beyond teaching. The study generated data from ten (10) purposively selected secondary school teachers. Using the thematic analysis method, despite participating teachers being able to conceptualise TL, they cited that, factors including; unmanageable teaching loads, inadequate induction, and use of top-down leadership approaches inhibited TL initiatives. To mitigate the abovementioned factors, participants suggested the creation of a supportive school environment, teacher training and recognition.
