Don’t Criticize Them
It’s easy to tell your supervisor that they are wrong, especially when you present facts in front of them. It can also be easy for many people to bring up a mistake or tell them that they didn’t perform a task correctly, especially when you know the right way to do it. When you work with someone who doesn’t have Narcissistic Personality Disorder, they’ll better handle the criticism or information. When dealing with someone who believes they are never wrong, you can’t allow yourself to fall victim to their cold-hearted and manipulative ways, so it’s best and more comfortable just not to say anything.

A narcissist can spark into a fit of rage when they’re criticized. They can’t take it, not even constructive criticism. At the same time, they might not even acknowledge what you said because, as the old saying goes, it falls on deaf ears.
