I would advise taking acting classes. No, I'm not trolling. It can teach social skills and also make corporate life a lot more bearable. Public speaking is good, too.

Sometimes you have to act subordinate, while keeping your poise. Play the character, do the role well, but never actually be subordinate. Always keep your own career goals (knowledge, contacts, credibility) in mind and protect them, because corporate incoherence will assault your goals from all sides. It's rare that anyone will look out for you, and usually managers can't (that's called "playing favorites") so you have to do that for yourself. Your real boss is someone you can't get away from but who can't fire you: it's you.
