To add to the parent poster's advice of looking for somewhere else and not participte (which will take huge efforts and sacrifices), in the same lines of reasoning that we are what you eat, that we are the sum of our habits, we also eventually become our working persona. If you don't like the behaviours and ethos of the people around you, ask yourself if you're OK to become like that, because you will, and not just in your work but it will become part of your personality, who you are, and how you behave with your friends and family. Also, life's too short to spend half of your waking time in a toxic environment.
