Male teachers and boys must be taught about sexism to support women and girls facing 'overwhelming levels' of sexual harassment and abuse, a union conference was told today. The National Education Union's (NEU) annual conference heard that a 'toxic laddish culture' pervades the country's secondary schools and sexism 'stalks the corridors and classrooms'. A motion passed at the conference said schools should have 'robust sexual harassment and abuse policies' in place so teachers and students feel safe. It noted the thousands of testimonials posted anonymously by students on the Everyone's Invited website, documenting sexual harassment and assault in schools and colleges.
