Relevant story from today:
I know some guys in a local group which at one point was Neuro, Neuro Surg and ortho. A few years ago, the local hospital offered to buy them out. Apparently their group was having some trouble, crappy building they invested in and were losing some money, or at a minimum not making as much as they thought they should. So the hospital makes them a supposedly good offer and they decide that for LONG TERM SECURITY, they should take it. Well, fast forward a couple years and one day out of the blue, the hospital tells them they're all fired, they're not getting their contracts renewed, not even for $1 per year. Rumor has it they weren't "profitable enough." They're closing the whole department. (Except the surgeons of course, because that cow is still producing milk.) Now they're all desperate, trying to scramble and find new jobs. Of course, private practice isn't a feasible option unless they want to start from scratch again because their practice was swallowed and shuttered, or unless they want to go be the ground level b¡tch of one of their former competing groups.
I just texted back and forth with one of the guys offering to give him a job as my group is looking to expand and add more specialties. He responded with telling me the above story, and with "Its so crazy, I can't believe it. It's so crazy, man" mixed in too many times to count.
My conclusion is that taking a hospital employee job, though it may work for the right people in the right situation, involves giving up autonomy for "security" which in many cases, may be a false promise and not at all secure. Although I know there are no guarantees (false or real) in private practice and that my salary could drop, at least I know I won't be told by some administrator it's dropping to zero, by no fault of my own.
