In some states (most? all?) I believe wording a contract like that is unenforceable. A group that exists to provide anesthesia at a location cannot claim damages from you working in the same geographic area after that group ceases to provide the service that they don't want you to compete with. It's a "non-compete" to prevent you from competing with them. If they aren't in the game, there is nothing to compete with. The only caveat would be if you were contracted to work with someone else before the group folded. But once they are gone, you are probably fair game to work anywhere as you can't damage a group that doesn't exist.
That is exactly the scenario that non competes are very effective in. Anesthesia group X has one hospital that it provides services for. The hospital wants big give backs at the next contract renewal. The controlling votes of the group decide to say "NO". The day comes when the contract expires. The hospital goes to the individual group members and tries to get them to break ranks. The non compete the doc signed
with the group prevents them from breaking ranks. Even though the anesthesia group is no longer providing services anywhere, it is still a valuable business asset during potential negotiations. If you are talking about this noncompete preventing a doc from going elsewhere within the geographic radius, I don't know how enforceable it is. Or why the group would choose to enforce-maybe vindictiveness. The hospital may have a noncompete with the individual docs preventing them from working down the road. This noncompete should be very enforceable.
There are frequently multiple non competes.
1. The one that a doc signs with the group that prevents him from competing against the group.
2. The one that each member of the group signs with the hospital in exchange for the exclusive contract preventing them from working as individuals at a competing health care facility
3. The one that the anesthesia corporation signs with the hospital preventing the corporation from providing services to the competition.
We have all three. Our lawyer tells us they are all enforceable where I am under current law.
Enforceability of any or all of them varies from state to state, even within states, exactly how it is worded, and what mood the judge is in.
