I used to be a Chair of Governors at a local school . I dont agree in fining parents, schools expect a lot of goodwill from parents throughout the year and I always felt that if you do fine parents then you can potentially lose that
But school is important , children with poor attendance dont do as well in exams thats a fact, most parents value a decent education above a cheap holiday, for those that dont then fining them will have no effect
Lets not forget that teachers always need to take holidays at the worst times.
