Had a conversation with my headteacher today about September and that if guidance is still the same then I may not be allowed back in to school or my role will have to change. She then said that if guidance doesn't change (which I know is uncertain at the moment) we may have to discuss when I go on maternity and start it earlier. Its not that I'm not willing to work, I want to work, I want to be there now for God sake and it was her choice to keep me home, but can she force me to change my leave start date due to something out of my control even though I'm willing to work?
