She would definately have to still offer you the ongoing position even if she finds out that you are pregnant... whether she does or not is a different issue and unfortunately there are loopholes for prins who don't want to do so. They can claim declining numbers (obviously has to be backed up) family leave, and a few others that I can't remember off the top of my head. If you are a member definately call the AEU and see what they say, they are really helpful and will give you a few scenarios. If she has said so far that you are going to get the ongoing position, then changes her mind if she finds out you are pregnant.. well there are serious implications for her if you decide to take it further with the union...I hope that helps - good luck.
