You seem pretty frustrated, maybe a little angry too. Well that's understandable, common even. I've certainly been there myself. One thing I can tell you for sure is that fighting any battle against management almost always demands a toll. You have to pick battles you can win and you have to fight those battles without being perceived as combative or just another disgruntled employee with an attitude problem. Allow yourself to lose your head and you've lost, maybe more than you can afford. And you'd be well advised to keep any ideas about legal action to yourself unless or until the papers are filed with the court.
So take a look at what specific problems you can contribute to solving and figure out a way to do it while presenting an image of helpful concern and a positive influence rather than someone who threatens the well being of the company and brings down morale. The best corporate in-fighters never seem to look they're fighting!
Hey good luck with whatever your issues with your employer are and be circumspect in what you say about them here.
