Interesting job might be coming up in my area, same employer so I'd keep my maternity rights but different unit.
I hadn't thought of a move yet because of inconveniencing people but a colleague recently successfully applied for and got a management job while in early pregnancy and no problems from anyone.
If I was actually pregnant I'd be up front about it but it seems a bit tricky when ttc. (got pregnant with dd v quickly, but could be different this time). Would you?
