There are times when burning bridges is EXACTLY the intended purpose. I have seen, even as recently as last month, where a medical director walked off the job and it caused such chaos that the entire pathology group with the practice contract was terminated by the hospital near instantly. This WAS the very intent of the pathologist who left, with no notice.
Walking off a job and leaving a burning wreck is sometimes the only leverage a pathologist has these days.
Sad but true....it's a Jungle out there. And unfortunately it's a Jungle in Vietnam circa 1968 with V.C., tigers, booby traps and all sorts of crap!
