I'm returning to work in October after a year's maternity leave. I've asked to go part time to 0.8 which has been granted but they want to change my contract to temporary. Can they do this? I'm a teacher and this has happened to 3 TAs in school (new head who would prefer all full timers) one left and the other two went to full time. I will contact my union tomorrow but had the conversation earlier this evening and now I'm panicking about my job security.
