Hey
I have been offered a clerical/admin job with the NHS. I have to ring recruitment to express my interest in the posts available (which I haven’t been informed of yet.) The problem is I’m pregnant and just about to take maternity leave for a year. Should I inform them of my pregnancy immediately or get an offer in writing first for the post I’m most interested in? I don’t know how my prospective manager would feel about having to wait a year for a new start or what the rulebook is for this situation. 
I must add I work as a casual worker with the NHS already so HR are already aware of my pregnancy and maternity leave.
