> Not enough of them to put off many employers from doing the things that they could be sued for, it would seem given how many companies behave.

I've talked to corporate lawyers about this. Larger companies have teams of lawyers dealing with an incessant stream of lawsuits by employees. A large percentage of them are completely without merit, and both parties know this. But it's cheaper to settle than go to court, which is why employees sue for the cash grab. It really doesn't matter how well a larger corp treats its employees, they'll get sued again and again anyway.

A larger corp is just a bigger, fatter, juicier target for lawsuits.
