I recently accepted an offer with a large organization and started five weeks ago. This morning, another potential employer I interviewed with once (at the same time I interviewed for my new job) offered me the position I applied for. While I don't have any problems with the job I just started (and the employer), I would love the other position more, and it has more responsibilities and better pay. Any advice as to how to handle such a situation? I don't want to burn any bridges since I might want to go back to my current employer someday. I suppose I could tell them I left to advance my career, but I don't know how they would take it.
