I’ve just done this. Interviewed (for a promotion) long before I knew about pregnancy, found out I got the role the same week I found out about bump. I’ve had a lot of losses, so talked it through with my partner and decided to take the role.
I’d a long notice period (4 months). So have worked it and just started in post at 25 weeks and told my new employers this week. They are (understandably) not thrilled but they’ve been kind/accepting of it (which is understandable as it will leave the department short staffed. There’s a high vacancy rate in what I do so while they will advertise the post they are unlikely to fill it). I’ll also be entitled to Mat. leave (but it’s absolutely something to triple check).
Clearly I chose NOT to share, I attended some training days and actively hid my pregnancy. The reality is that my contract could easily have been withdrawn
(“oh sorry the post’s funding has been altered”/“projects changed”) or any other excuse used to not honor their offer, and long-term…I’ve earned the role. I’m excited to be working in it.
However, I suspect what works for you depends on the environment, your team and your circumstances BUT don’t let guilt make a decision for you. It’s ok to be pregnant and want to progress your career!
I always read on these posts to tell them, but the stats about maternity discrimination say otherwise. And again often the argument is made that if work respond in a way that’s not favorable, then it’s likely not a team you’d like to work for anyways. Yet, in my line of work, those choosing to withdraw the contract would be people I’d never had to deal with on a daily basis!
