This is pretty much what was implemented in Finland starting last year. If an employer wants to keep a non-compete clause in a contract, they are forced to pay their prior salary for the agreed period (max 12 months) after employment - regardless of where the employee chooses to work afterwards. If they go to a non-competitor, they can start immediately and get their new salary on top of the non-compete compensation. Needless to say, nearly all non-compete clauses were systematically removed from existing employment contracts.
