So the callout to be wary of them is totally legit... but it doesn't look like they are going to be enforceable when such things go through the courts.
I’d rather not carry the cost of learning it’s not enforceable.
Not sure how that's going.
"Defendant has never worked in any other industry. He has three kids. He's gotta work."
(That's for regular employees--it's a different issue with founders who may have significant equity stake and such.)
The worst is that they can delay the case for years, leaving you in a legal limbo. Or go after your employer, involving them in the discovery process.
