What do you do about a colleague who is always telling you how to do your job? Or someone who seems to always have the answer, implying that you don’t? Or a coworker who uses a patronizing tone whenever they talk to you? Dealing with a condescending colleague can be frustrating, demoralizing, and even infuriating. And while it certainly doesn’t feel good to interact with someone who monopolizes conversations or consistently positions their ideas a superior, these interactions can also negatively impact your reputation and career.
