Kids mum is planning to take children out of school for a cheaper holiday (£600 saving which isn't all that great I don't think). Wasn't too concerned when they were in primary but now the oldest is in secondary I'm not too happy about it. She says once is fine but if it happens this years it will happen every year. I try to talk to her about it but she doesn't listen and gives it "it's fine".
Can I / How do I protect myself from any repercussions?
