Yes, a good lawyer will always have a choice of law provision, as well as venue and jurisdiction. Whether a court will always enforce the choice of law is another matter, though. I haven't looked at it specifically, but I suspect for policy reasons a company can't get around California's general prohibition on noncompetes with employees by having a choice of law provision.
Are you saying that if the contract says, as they all do, that this contract will be governed by the laws of State X, a "good lawyer" can have that part of the contract ignored? I would find that difficult to believe.
