Over the years as an international family I have had to manage summer holidays with schools and grandparents (working) in two countries
Summer holidays days aren't the same around countries.
This year I have arrangered two weeks for me, DH, DS, DD1 and DD2. We are based in two countries. DH is a teacher and DD2 in secondary school. DS has fixed holiday this year. DD1 gradutes a master from a university with a fixed examination day. Great fun.
I asked Headteacher for DD2's school for two weeks off. DD2 has no exams this year.
As we relocated to Europe at Christmas and rules are different DD2s Headteacher wrote "Lovely to get the family together see X in August. Enjoy!".
In England I would have paid the fine and thought "oh well" because it won't add up trying to navigate school and work this year in two countries.
I find England ridiculous but I would have paid if I was this mum and thought oh well carry on.
