Sorry to rain on your parade, but it's good to have reasonable expectations.
Laws enable you to extract a pound of flesh from people who have mistreated you. They do not prevent people from mistreating you. You can use it as a shield, if they decide to fire you -- you can say "oh, you know that's illegal, right?" and they might back down. Lawsuits take years and cost lots of money unless you get a great lawyer who will work pro bono.
