Hi, I have just started my maternity leave and will be returning to work in April. When I left I was part time, working the beginning of the week. When I return my head would like me to work the end of the week. I originally agreed but have now had time to think and the beginning of the week is better for me with childcare. Do I have any right to choose my days? I am primary and job sharing but there are a few different job shares in the school.
