I completely agree with Grimmy's post. In my experience, MD's who are consistently rude/mean are simply acting out their own power trips, and the worst thing to do is to act intimidated or scared. That's exactly the reaction they want, and it simply encourages them. If you remain professional, polite, and calm, and respond to their irrational/unreasonable questions, demands, and comments with simple logic, they'll learn that you are immune to the crap they try to pull and will generally knock it off when dealing with you. It's hard, especially when you're new and docs seem like total authority figures, but remember this - without you, docs would be helpless. Who gives them the majority of the info. they need to make decisions? Who does the great majority of assessment for patients? Nurses. Don't let 'em make you feel insignificant or like a servant. And if it gets really bad, definitely report the behavior to your boss, in writing, with a request to inform you of the follow-up action taken. You should never, ever have to take abuse from anyone you work with.
