This may not be the popular point of view, but if you sic the government or a bunch of lawyers on your company, they may not be able to fire you, but they sure can make your life hell while you're there. There are all sorts of ways to make someone want to quit without breaking the law. You'll end up on the bottom of the heap with respect to any new perks. Meanwhile, your name is at the top of their downsizing list. They can give you every ****** job they have. All things being equal, it may be better to part ways with them on good terms and find a job that will let you work fewer hours.
