I'm working a contract job and was offered a salaried job at the company but turned it down after holding on to the offer until they put pressure on me to make a decision. I think they knew that I was holding on to it as a backup plan while trying to get an offer somewhere else. Well, I pretty much do have an offer somewhere else, but that somewhere else has to first do a background check and wants professional references. I would feel awkward using my manager now that I just turned down a job that they generously offered me. What should I do?
