I'm a GTP at a secondary school and have been ASKED to help out by accompanying another member of staff on a trip. I happily agreed but have since been asked if I can pay the same amount as the students to go on the trip...£15. I said yes, as the trip can't go ahead otherwise so it wouldn't be fair on the pupils but it's been bugging me as it doesn't seem fair that I have to pay to do my job. Does anyone know if this is standard practice? Thanks.
