I've been sick now DS is sick so I'm off work with him which isn't good with my contract expiry coming in 4 weeks. I'm quite nervous. I'm also 8 weeks preg and having a moral dilemma as to when to tell them
I had a similar situation on a contract between DD and DS, with the being pregnant and deciding when to tell them. In the end I told at 8 weeks because I wanted them to know at point of renewal, I was fairly convinced they would still renew but prepared that they might not. In the end I think it worked in my favor as the amount of work they had fitted perfectly with amount of time I had before would want to finish up and I think it in a way made it easier for them to renew as knew were definitely only committing for a set time and I wouldn't be trying to extend it by creating work I would be motivated to finish IYKWIM (in my arena it is not uncommon for contractors to string work out to keep contracts going). The company had been my employer before DD as a permanent though so I did have quite a good relationship with people there, which also made me want to make sure kept them informed.

Is tricky though as there is no right or wrong time to tell about pregnancy. Also remember is unlikely they would have any moral dilemmas about letting you go. I assume here in Aus that contractors can be let go at any point without company even having to give a reason? E.g. Unfair dismissal regulations don't apply?
