Hi Cleo, You wouldn't be the first teacher to be" poached" from an agency by a school. At the end of the day you have to put yourself first. I would ask to speak to the person in school who sorts out the supply, and to explain that you would prefer it if they didn't mention that you were carrying out supply directly to the agency. The school could possibly get charged a finders fee by the agency if they find out so they won't be keen to put their foot in it. I'm naturally a very honest person, however working for supply agencies has taught me to economical with the truth and to make sure I put myself first, as the agencies have no real loyalty to teachers. Good luck and I hope you manage to get some more work.
