I'll keep this a brief as I can 
I am a teacher. I finished work in April to have DD. I need to return to work in September as a full time CT as we can't afford more time off (New school/surprise baby so only maternity allowance).
My friends, also teachers at different schools, have asked if I am going back on the last day of July term so I get paid for the summer.
Is this really cheeky? Has anyone else in a similar situation done this? Can they say no?
Thank you.
