Ok so my head has told the classes who had teachers striking last time that they won't be in for the next one (being fair to parents to give them chance to reorganise), but we can decide as teachers up to the day whether we strike or not. I'm totally in favour of the strikes because schools in England are falling apart. There's no funding for anything.
However I can't really afford to strike. If you had a child in my class, arranged childcare for that day (or took a day off work), but then found out that the teacher wasn't actually striking si children were expected in school, how would you feel?
I really don't want to upset parents.
