Many people from around the world have emailed me with this question: "What do I do?" with my current bad boss/organization. Unfortunately, apart from the usual don't-bully-me tactics that you can learn about elsewhere, my suggestion is: don't take on your employer. Just find another job.
If you do take on your employer (ie, a dictatorship system), here are some of the things you stand to lose - your job, your peace of mind, money (if you decide to sue), and so on. What do you stand to win? Not much - you probably get to keep your job, but you've antagonised your employer, and boss and colleagues as well for "creating trouble."
The only way to change things is to aim for the long-term: raise awareness, so that the system changes.
