Last Wednesday my boss e-mailed me and stated that I would be going from temp to permanent status. However I was never told I was a temp. Then on last Friday my boss gives me a review and rates me low on performance standards which I did not agree to, and then contradicts herself and says that they were not sure if they wanted make me permanent yet. So I would have another review in June. I want to check my rights as I would not have taken this job if I was a temp. Likewise I was told in an email prior that I would be going to permanent status. Is something fishy here? What should I do? I'm afraid as Colorado is an "at will" state. Thanks!
