"Also I read in Nevada that some judges have ruled that if you were getting positive feedback on your performance from your employer , you can reasonably expect that your job is secure. therefore if they terminate you without warning, they were in violation of the covenant of good faith."
Secret hidden knowledge about employment and labor law that none of us have heard of and none of us can come across in searches of employment law...hm? Okay. If you were getting positive feedback on your performance from your employer, you could reasonable expect that your job is secure from an unemployment insurance perspective. In other words, if fired under these circumstances, you would be more likely to be approved to draw unemployment benefits but not given your job back by a court of law judge (not an agency judge) and granted backpay or damages in civil court, no. I think you've been hitting things at random on the internet and combining unemployment law and labor laws and coming up with this sort of thing. But really, I hope the union can get you the job back and they will then of really be stuck with you once your probationary status is gone in a union environment. This just means you will have your job back, not that everyone will now be forced to be nice to you, though.
