Reader's Digest version is that when I was offered my current job, it came with the promise from my former colleague doing the hiring, "If you don't like the job, I have lots of contacts and will help you find something else." I didn't really want this job as it's 100% accounting... something I'm really not fond of and not really trained for. She needed someone asap and made the offer of help down the road.
Fast forward a year later... I told her I'd like to take her up on her offer to help me find something else. A week later I was in her office with our HR person being told it wasn't the boss's responsibility to help me find a new job.
They started running the ad for my replacement this week, despite the fact that I don't have anything else lined up.
