I really like the way Norway has done it. A couple of years back they introduced a law that to make non-competes enforceable the company would have to pay you a full salary for the duration that you're blocked out of other work. Non-competes has function, but it's far too cheap for the company and far too expensive for the employee. Now the employer has to consider whether it's a position it's worth to protect or not, rather than just put it in the default contract
