I've just been told by HR at work that I need to let them know by next week (25) when I intend to start my maternity leave. The thing is that I dont have a clue!! My job isnt particually demanding (IT helpdesk - IT queries over the phone), and ok hours 9-5, so i'd like to leave it as long as possible if i can. When are you all planning on taking yours? Would 37 weeks be too late?
