Yep. Used pretty often. Attempting to fight things like that without a union backing you is scary and risky enough (plus lots of people just have no clue what the law says—which, who can blame them when it hardly matters?) that it usually works just fine. Probably a little more dangerous with employees as well-paid as at FAANG, but then again, if they ever want to work at that level anywhere else, they're not gonna want to rock the boat that way.
