Flexi working and probationary period

Hi ladies,

I'm new to this forum and wondered if any of you knew what i could do.

Grace is 7 weeks old and i'm not due to return to work until April but i'm a bit worried about the situation i'm in. I started my job in January this year and didn't know i was pregnant when i started. On my first day i started bleeding and work called an ambulance, got taken to hospital and found out i was nearly 8 weeks pregnant. I was signed off work quite alot during the pregnancy as the bleeding was on and off until 20 weeks and then i got severe SPD. Because of all this the company said they will start my probationary period again when i go back to work.

The problem is i don't want to go back full time and will need to put in a request for flexible working. Does anyone know if they can refuse on grounds that i'm not a permanent member of staff yet?

I would be grateful for any advice )
