Many organizations have a toxic top performer. It’s the attorney who lands the biggest clients, the sales rep who blows past quota every quarter, or the rainmaker whose numbers are untouchable. They are also the reason three people on your team updated their resumes this month and why there is an ever-revolving door of support staff in their departments.
The toxic top performer is one of the most difficult personnel challenges in any organization, not because of what the correct action is, but because the short-term math is hard to argue with. When someone is driving significant revenue or winning high-profile cases, the instinct is to look the other way. Unfortunately, that instinct is a liability, and it’s costing you.
45 Solutions can work with your team to implement reasonable strategies to address toxic employees who drive revenue.
The Worry in Their Wake
Rainmakers can make it rain, but they can also make everyone miserable. The damage a toxic high performer does to the people around them rarely shows up on a spreadsheet. It shows up in exit interviews, in quiet resignations where individuals are scared to speak up, and in the steady loss of good people who simply decide the environment is not worth staying for.
We have worked with many teams familiar with this pattern. When there is a toxic coworker, others are more than likely helping cover their tracks out of fear. An office manager absorbs the fallout, covers the gaps, and manages the difficult behavior because no one above them is willing to address it. A culture of tolerance takes hold, and the unspoken message becomes clear. Results excuse everything, including bad behavior. That message spreads and becomes far more contagious than any top performer’s work ethic.
The Price of Looking the Other Way
Toxic individuals will demolish your team’s morale, and this is no small matter. When a toxic performer is allowed to operate without accountability, the ripple effects are concrete. Productivity drops among those stuck working alongside them. Collaboration breaks down, leading to failures at multiple levels. High-potential or other high-performing employees start exploring their options. You end up paying a price in turnover, recruitment costs, and the loss of talent you simply couldn’t afford to lose.
Even those who do not work directly with the toxic individual may leave for fear of being associated with their behavior.
There’s also a legal dimension that cannot be ignored. If employees are experiencing harassment, a hostile work environment, or retaliation for raising concerns, their unaddressed complaints won’t stay internal for long. Those complaints become costly legal nightmares.
Documentation is not optional. Every complaint, conversation, and coaching session needs to be on record. These aren’t meant to build a case, but rather protect all involved. The absence of documentation can be a risk itself.
How to Protect Your Culture from Toxic Employees
Culture is shaped by what you tolerate and by your repeated actions over time. It is not just what you say but how you act out your values in your business. If your stated values include respect, collaboration, or integrity, but a top performer is visibly violating all three without consequence, your culture is in jeopardy. The question is whether or not you’re paying attention and taking action.
Start with a clear, consistent process for those who raise concerns. People who come forward need to know there is a clearly outlined path. They need to know that their complaint will be taken seriously and that they will not face retaliation. This is both a legal requirement and a cultural one. It’s your job to protect your people and protect your organization.
How to Take Action with Toxic Behavior
Addressing a toxic top performer requires a deliberate, documented approach. Start with coaching. Be direct about the specific behaviors that are unacceptable and their impact on the team. Move direct reports out from under their influence where possible. If coaching does not produce a change, counseling and a formal Performance Improvement Plan are the next steps. A PIP is not just a precursor to termination but a structured opportunity to set expectations with consequences.
But ALL of this needs to be done with extreme care. Our team at 45 Solutions has tackled this type of situation before and can help you shift the toxic behavior.
If it comes to termination, don’t underestimate what that moment can do for your organization. Letting go of toxic employees sends an unmistakable message to everyone watching. What you produce and how you treat people carry equal weight. Sometimes the best thing you can do for your team is show them exactly what you will and will not tolerate, no matter who it is.
