I'm currently on maternity leave having had my baby last October. I'd like to return to work in July, full time, for two weeks but then go to part-time from September. Is this possible? Or is it being really cheeky in terms of August pay? Can I state in my return to work letter that this is what I would like? Or do I need two separate letters, one with return to work for July and one to request flexible working from September? Thanks in advance.
