Hi all, i am a first time mum of a 9 nearly 10 month old DD. I originally had no plans of returning to work but a fixed term opportunity has come up and I feel it is foolish to dismiss it out of hand.
The decision I need to make is quite time pressured. At the moment what I am struggling with is the financial side of things. I am trying to figure out if what I have been offered is actually viable, and also I am a bit paranoid about my financial calcs on so little sleep.
Please may anyone help me? This is also my first experience of part time work and pro rating etc.
Please may you advise how to gross up income etc, for tax and NI so that I can work out what my "bottom line" should be? Also how to pro rate for a 4 day week 
Probably very basic questions but I've tried to do it but just want to be sure before I start negotiations
