What if these behaviors were not a coincidence, but known patterns identified by behavioral science? This is precisely what Amy Gallo, a Harvard-affiliated researcher and specialist in professional dynamics, did in her book “Getting Along.” In collaboration with the Harvard Business Review, she identified the 7 types of toxic personalities at work. Their common point: exhausting others while spoiling the team atmosphere. Behind their attitude lies a very precise mechanism… which we can finally understand to better cope with it.
How to identify these personalities who exhaust those around them?
Each toxic profile manifests itself through specific signals. Amy Gallo analyzed them, combining psychology, neuroscience and field experience. It warns: these behaviors, when ignored or poorly managed, directly impact the productivity, creativity and mental health of teams.
“Stress from interacting with difficult people dampens our creativity and productivity, impairs our ability to think clearly and make informed decisions, and causes us to disengage“, she explains. Worse still: “too often we avoid things as if we have no choice“.
In her analysis, the expert identifies the following figures:
- The narcissist: thirsty for admiration, he constantly seeks to shine by belittling others. Not very empathetic, he manipulates to achieve his ends, often to the detriment of the collective;
- The paranoid: every remark is perceived as an attack, every decision as a conspiracy. His permanent distrust creates an atmosphere of tension and suspicion;
- The passive-aggressive: he sabotages without showing himself. Delays, sarcasm, and ill will are his favorite weapons;
- The manipulator (or playwright): incapable of recognizing his wrongs, he plays comedy to divert attention from his errors. Every problem becomes a melodrama;
- The control freak: obsessed with detail and perfection, he imposes his rules and restricts any form of autonomy. A brake on innovation… and atmosphere;
- The eternal victim: never responsible, always persecuted. She blames others and demoralizes her colleagues;
- The compulsive-obsessive: a perfectionist to the point of excess, he spends more time checking everything than moving forward. Result: processes are slowed down, frustration mounts.
These profiles, although different, have one thing in common: they undermine the balance and morale of the teams.
What can you do in the face of these toxic personalities without burning out?
We don’t always choose our colleagues. It is therefore crucial to learn to interact without falling into the trap of permanent confrontation or emotional exhaustion. Amy Gallo encourages avoiding automatic responses and understanding the driving force behind these behaviors to better circumvent them.
When faced with a manipulator, there is no point waiting for him to recognize his share of responsibility. When faced with a paranoid person, arguing rationally can sometimes make things worse. Rather, it is about adopting a targeted adaptation strategy and staying focused on your own priorities. It is therefore not a question of changing others, but of modifying one’s posture, refocusing energy on work, and preventing toxicity from contaminating the entire team.
Why knowing how to recognize them changes (almost) everything
The impact of toxic relationships at work is often underestimated. However, in the long term, they can cause professional burnout, disengagement, or even chain resignations. Hence the interest in putting words to these invisible, but powerful, mechanisms. Identifying these profiles means regaining a form of control. It is not a miracle solution, but an essential first step to protect yourself, because you cannot change what you do not know.
This knowledge becomes a way to improve things and move forward without getting sucked in by toxic dynamics.
