I'm not sure what the laws in CA are exactly, but here (EU) non competes don't work generally. If you are a programmer and you go work as a programmer for the competition then even if you signed stacks of non-competes, they cannot be enforced. Simply because you are a programmer and not allowing you to take that job would mean you are potentially without a job which is about the worst thing that could happen. Most non-competes refer to you resigning and taking clients with your but even that is hard to enforce. The basics are ; if you are a nice company to work for and with, you have nothing to fear.
I know first hand of a few cases of non competes working (in France), and they all involved the ex-employer paying substantial amounts of money for the time the ex-employee was prevented from working for the competition.
Also known as garden leave. You're basically still 'employed' but you're kept out of the office with all access revoked. It's to put some distance between any time sensitive info from one job before you move onto the next. In the UK, I think the banks do this for three months.
The original employer must continue to pay a "significant" part of employees pay as long as non-compete is in effect and has to state clearly that they will do so in 14 days after the employee has left the company. Otherwise the non-compete is void.
Yes, which is a workaround as people get paid. If they didn't get paid it wouldn't work. As said; they are actually still employed but not working anymore.
That's very unrealistic and naive. Non-competes are quite enforceable in the Netherlands, which is why me and many people I know refuse to sign them.
Yes, companies that enforce them are rare and complete dicks, but they can and some will. Companies that won't don't need them either, so either way the negotiation about the non-compete becomes a very brief one.
EU doesn't have a harmonized legislation on non-competes. They can certainly be enforced in Finland, even though they're unheard of with typical employees. Normally only executives have them.
Yeah shouldn've have said 'EU' but rather name countries. Still; everything I read so far contains 'within reason', the Finnish rules as well which means that when it gets to court (if ever) it'll be thrown out for most as non-competes are not reasonable in a lot of cases. Especially, like you say, for executives / top managers who actually carry deep knowledge of the company which can hurt them going to the competitor.
