In partnership with
Leadership Challenge - "HOW DO YOU HANDLE A HIGH PERFORMER WHO IS TOXIC TO THE TEAM?"
Answer: You coach them first.
Be direct: "Your work is excellent. Your impact on the team is destructive. Here's what needs to change.”
Document specific behaviors: interrupting people in meetings, taking sole credit for team work, yelling at colleagues.
Get witness statements. Make the expectations concrete.
If they change, keep them.
If they don't after genuine coaching and proper documentation, consult HR/legal before the final conversation.
Great work doesn't justify destroying team morale.
One toxic person can crush ten good people.
Choose the team.
Question to Consider: Is their output worth losing three other people?
Why: Toxic high performers are cancer.
They spread. You have someone who's brilliant. They ship. They solve hard problems. But they're an asshole. They belittle people. They hog credit. They create drama. You tolerate it because they produce. Meanwhile, the team is suffering. Good people are leaving. Not because of the work. Because of this person. You're losing three good people to keep one toxic one. That's bad math. The cost? Your team morale dies. People stop collaborating. Everyone walks on eggshells around the toxic person. Your best people leave. The ones who stay are either toxic themselves or too beaten down to leave. You've created a toxic culture. All because you valued output over culture. You're the problem. You allowed this. You told the team through your inaction that performance matters more than people. Now they believe it.
Action: Confront them today. "Your work is strong. Your behavior is unacceptable.”
Here's what needs to change: collaborate, share credit, stop belittling people. You have 30-60 days with weekly check-ins to fix this.
Toxic behavior is urgent, lean toward 30 days unless you see genuine immediate change." Document everything: specific behaviors, dates, witnesses.
Coach them genuinely. Track progress in writing. If they don't change after real effort and proper documentation, consult HR/legal before making the final call.
After termination, keep team communication professional: "We've made a personnel change. Our standards include both performance and behavior. That's not changing."
Don't discuss specific reasons (legal/privacy risk).
