For those who raise safety issues and feel they were punished or retaliated against for doing so, I recommend you go here:

The law was written specifically for you. The FAA will ensure the safety concern is properly investigated, and OSHA will determine if a labor violation occurred and can order restitution. It’s still the government so it can be frustrating at times, but there are dedicated offices to handle these kinds of situations...
