The non-competes I've signed have offered 60% of my base pay for six months (the length of the non-compete) if I cannot find a job because of the contract if the company exercise it.
They never have exercised it for me.
The types that are banned are ones that set the restriction as a part of a normal employment contract, where there is no specific compensation given for accepting the non-compete and where the employee can't decide to abandon the non-compete in return for not getting the extra money.
So even if you sign that clause you are not bound by it.
Employees thinking they are subject to legal penalties/fight due to a non-enforceable non-compete gets the company 90% of what they want, anyway, and so to prevent that they should be strongly punished.
Jimmy John's was making its low-level employees sign non-competes, for example. This was ridiculous on its face, and probably wouldn't hold up in court. However, the people affected by it were least able to take it to court.
Partly it was naked power.
