> I think if you threaten to sue your employer, the employer isn't too much at fault and just covering their own neck when you later threaten to resign and they take you up on that offer.

It's not clear to me here what you're advocating for -- a lawsuit wouldn't be raised by such an intelligent and virtuous individual unless there was some clear wrongdoing. Are you saying that you think workers shouldn't sue their employers if their employers are breaking the law?
