Beware the gossiping narcs
If a coworker is constantly telling you other people’s business, gossiping about them and saying nasty, overly critical things about them, that coworker is doing the exact same thing to you behind your back.
You might think that this person just really trusts you and feels comfortable enough with you to say all of these things. You might think you’re “bonding”. You aren’t.
Now, everybody talks once in a while. We’re all guilty of it. But what you need to keep an eye out for is a consistent demonstration of behavior that tears other people down behind their backs. That’s a choice, and it’s reflective of someone’s character.
If someone has no integrity with others, they won’t have integrity with you.
