When best to tell new job

[GinaFordAteMyBaby]

This might not even be an issue as I might not get the job, but I had a job interview yesterday which I think went pretty well and I'm wondering what to do about telling them I'm pregnant if offered it.

I work for a large organisation and have applied for a job internally so there should be no issues with maternity pay and such. I didn't mention the fact that I was pregnant at my interview as I thought that in reality it would probably count against me, but don't know what to do if I'm offered the position. Should I tell them when it's offered or wait until I'm in post and then tell them (I think it would be kind of obvious by then). Any tips for softening the blow?

HOw far gone are you? Depending on that, I'd tell them if and when you are offered the job (provided you are past the 12 week pt).

Hi, love your nickname . One part of me says that there is (or should be) no blow to soften. If you are good enough to be offered the job, that is it - full stop. You happen to be a woman of childbearing age and a pregnancy with its associated maternity leave is something your employers and you have to factor in.
The other part knows how difficult it is and that you are likely to feel bad about applying for a job "under false pretences" (please don't crucify me Mumsnetters - read the first paragraph again; I am just reading between the lines of the OP's post and know where she is coming from).
I am glad that the interview went well. If you are offered the post, as it is an internal application the initial offer is likely to be verbal. If you want to accept, do so, verbally, but wait for the written offer before showing your hand (or your bump). Once you have the written offer in your hand, accept in writing. I would not mention the pregnancy in the letter of acceptance as this forms part of your contract of employment. The issue of pregnancy is better dealt with separately.
In law, you do not have to inform your employer of pregnancy until 15 weeks before your due date. As your condition will soon be apparent, and you will want time off for antenatal appointments etc, you will not want to wait that long, but it is generally a good idea to write a separate letter for the pregnancy issue.
Whatever you decide to do, good luck with the job and the pregnancy.

Thanks. In the end it's not an issue as I didn't get the job. :{ So now I just have to deal with returning to a job I hate with no prospects for the THIRD time next year...
