How to spot a toxic co-worker, as per psychology

A toxic coworker often feeds off office drama and uses gossip as a weapon. Psychologists note that gossip can be a form of indirect aggression — a way to damage someone’s reputation without direct confrontation. Toxic coworkers use rumors to make 'friends', isolate others, or maintain control over people. You’ll often find them at the center of every emotional storm, stirring up tension under the guise of “just sharing.” This behaviour can poison team dynamics, spread fear, and create a culture of distrust. If someone always knows everyone’s business and spreads it, proceed with caution. Better, just maintain your distance from such people.
