yesterday DS had. School trip and all parents in his class of 30 were sent letters asking for the £10 (so called) voluntary contribution and the permission slip to be signed, these letters were sent out 2 weeks ago - yesterday the teacher informed the class that she did not have permission slips back from 12 pupils and unless they are filled out there and then their children would not be able to go, so there was everyone filling out the slips and saying "oh I don't have any money' etc etc so out of class of 30 12 families children got to go free (and I am not just talking about ones who really do need to go free !) - surely the schools can add a date to letters saying the permission slip has to be back by a certain date etc .......it's crazy why is it the same parents feel obliged to pay and others don't !
