I had an email from the school today to say the school is in a cup final & they want as many kids from y4 up to support the team at the final. Coach transport arranged at a small extra fee. This is OK but this is the third time this year the kids have been brought to support the team. They are all missing a full day (so three days out of school due to supporting the matches). It is optional, ds really wants to go so I have given permission but is this the norm?
