“You have to fire them. That star performer who gets results but everyone hates working with—they're a C-player in my world because they're toxic, and keeping them is killing your best people.”
“I’d have the direct conversation most managers avoid. I’ve seen brilliant people become accidental diminishers because no one told them their intelligence was shutting everyone else down. Name the specific behavior, not the person, and make the team’s lost contribution as visible as their individual output.”
“One person's bad attitude can infect an entire team. I've seen research showing that exposure to negativity reduces cooperation by 30 percent and raises conflict significantly.”
“I've been there, and here's what I know: talent without accountability poisons the whole team. You have to decide right now whether you're willing to hold that person to the same expectations as everyone else—because if you don't, your other people will leave, and you'll lose them long before you lose the talented one.”
“You're enabling the problem by tolerating it. I've coached 2,872 leaders accused of toxic behavior, and organizations always tell me the same story: high performers get a pass. But while you're protecting their results, your best people are quietly walking out the door because one person's behavior matters more than their own wellbeing.”
“I'd start by asking myself whether I'd hire him into a different role. If yes, stop trying to fix what he'll never be great at—move him sideways to where his real strengths matter more than the damage his weaknesses cause.”
“Your team sees you protect performance at the expense of their well-being and you've already lost their trust; what you accept by silence becomes the culture you're building for everyone else.”
“I took over a department at a casino years ago where one of the top-selling employees was brilliant at her job and terrible to everyone around her. Management loved her numbers because numbers don't come with complaints. When I eventually let her go, staff came to my office one by one—not to complain, but to thank me.”
“You have to deal with it directly, and quickly. The cost of not having that conversation—to the rest of the team, to the culture, to the person themselves—is worse than any awkwardness in the moment.”
