My full time contract was coming to an end when I was 4 months pregnant with my first child. Instead of renewing it for another 6 mths as per usual, they decided they no longer needed the post. Convenient timing for them. I wasn’t actually showing and I have no doubt that if I’d left them in the dark about my pregnancy, they were going to offer me a permanent role. I chose to be honest, and yes I got screwed.
