My son is in year 7 and was going on a 1 night school trip costing £65. The letter said voluntary controversial £65. I sent the letter back with no money. A few days later, the teacher told my son to tell me I have to pay the money. On other trip letters he had bought back and it also says voluntary contribution. This was also the same in primary school. I may have got this wrong but I thought voluntary contribution meant you can make a contribution of what ever amount you want up to the balance, or none all. It does not seem the case and am wandering that is this a new polite way if saying you have to pay the designated amount stated.
