sorry if this is in the wrong thread and I should know the answer but funnily my brain turned to mush after giving birth!
Does HR have to write to you before you go back to work to confirm your stated date of return, and if so, is it 1 month or 2 months before?
Have got it in my head that they're supposed to write to you 2 months before, but may be getting it confused with my having to give 2 month's notice of any change in the date.
Anyway, haven't heard from them and I'm due back on 6th Oct.
