Would like some advice please! Our school is just opening for the classes whose teachers are not striking next week, yet the teacher who normally does duty at play is striking that day. I asked what we were to do, we were told either do a duty for our own class or don't give the class a break or take them out for 'p.e.' when they would normally have play. Am I allowed to do this? I'm keen not to undermine colleagues, but don't want to seem like a trouble maker! Any advice? Thanks!
