This paper examines the way lesbian identities are silenced in schools particularly through anti-lesbian harassment. Based on research with 30 self-identified lesbian teachers working across high schools in New South Wales, Australia, the discussion illustrates how various responses to anti-lesbian harassment silence the recognition of such harassment, contributing to the invisibility of lesbian identities in schools generally. The argument highlights the shifting nature of both the subject and power. It illustrates how discursively (re)positioning harassers re-establishes and reinforces the harassed teacher's personal and professional power; however, this simultaneously serves to rationalise the harassment. This silences the awareness of the prevalence of anti-lesbian abuse by individualising the behaviour and pathologising the harasser, while ignoring broader socio-political discourses that maintain the frequently subordinated location of lesbian subjectivities.
