If it is a colleague that is causing you difficulty speak with your boss before it get’s out of control.
C.Y.A. (cover your tush). If you question the motives of your boss or colleague or are unsure of your position, document and date all minor or major requests from your boss or words that are negative from a colleague. You don’t need to leave room to stop being berated. If you can document and protect yourself from a misunderstanding or if your boss is purposely trying to trip you up, your notes will add protection. A quick follow up email from you reiterating and confirming the task, project or new initiative your boss has outlined verbally, will work in your favor if there ever is a question.
