Can anyone help please. I am on maternity leave and before i left my boss agreed for me to go back part time. I even put it in writing but did not receive a response from him. However recently he has told me that there is now no part time work available due to the credit crunch. Can i now change my mind and go back to my full time job? He says i cant and the girl will stay in my job and i will have to look for another job
