I'm not sure if lawyers think their words are magic sometimes, or if they'd just really like them to be magic.

I live in a state that prohibits most non-competes from employers, and any effort to try to get employees to sign overly restrictive agreements can actually result in a fine and penalty. My company sent me a legal agreement saying that by signing the doc and continuing to be employed, I agree to waive my state's protections against non-competes. As if... that would hold up in any court, ever.

It's a blatantly illegal clause and I could have fought it at the time... but in the end I knew it was totally unenforceable at worst. I'll go after them for the penalty if they ever try to enforce it, or if I leave under bad circumstances. It was more valuable to me to have this document than it is for them to have it.
