I don't get on with the head teacher of my daughter's school (mainly because it's a rubbish school and I have explained to her at length why I think this). We plan to go on holiday for a week in May which will tie in with a family wedding overseas - the headteacher refuses to give us permission (although other families in my daughter's class have been allowed to take time off for holidays). My daughter has 100% attendance record otherwise - is there anything the HT can realistically do if we just go or is it all bluster?
