I took a position at workplace "B" five months ago. I was supposed to cover for a maternity leave position. It is not in my usual field of work, but at the time I wanted something different.
Recently my previous employer offered me my old job back with a pay increase that I wouldn't be able to get at my current workplace. If i accepted the new offer, I would basically be going back on my words that I said during the interview process. I had told my current boss that I was sure this was something that I wanted to do. I'm afraid of burning bridges at my current workplace especially since one of the managers stuck his neck out to help me get the job. But at the same time, I really need to money. I don't want to look like I jump around from job to job. But feel like my previous job would be a better fit for me. What should I do?
