Some coworkers never raise their voice, never break a rule, and never do anything you could screenshot — but somehow, you leave every interaction with them feeling smaller. This video breaks down five specific, calculated behaviors that toxic coworkers use at work, and explains the psychology behind why each one works.

You’ll learn why “strategic incompetence” isn’t laziness — it’s a deliberate way to offload work onto someone else. Why public praise paired with private criticism is one of the hardest tactics to prove. Why some coworkers withhold information on purpose, and time it to make themselves look essential. Why fast, early “vulnerability” from a new coworker can actually be a way of extracting information they’ll use later. And why the quiet shift from “I” to “we” in how someone talks about a project can slowly move credit away from the person who did the actual work.

If you’ve ever left a job feeling confused instead of angry, unable to point to one clear reason why — this video will help you understand exactly what was happening, and how to recognize it before it happens again.
