A couple of weeks ago, my oldest son Dylan came home from work frustrated.
He’s in his twenties, finishing school, and working at a restaurant. He’s been in that industry a long time and he’s ready to be done.
That day, he told me about a change his managers had made to a process at work. He didn’t agree with it, so he changed it back himself. His managers weren’t happy.
The tricky part is that he’s also one of their best employees. He’s reliable. He performs. He’s been there a long time. Historically, they’ve loved him.
So after listening for a while, I finally said, “You need to be careful. You might be becoming what we call in my world a brilliant jerk.”
He looked at me, surprised. “What do you mean?”
I explained that sometimes at work, even top performers can become more of a headache than they are worth. And eventually, the leader will have had enough.
That conversation reminded me of how many times in my career I’ve helped a leader navigate this exact situation. It’s one of the hardest things a leader has to face.
Why this is such a hard problem
Brilliant jerks are hard to deal with for one simple reason: their performance is easy to see but the damage they create usually isn’t.
It might be your top salesperson. It might be a senior leader who has delivered in some big moments. It might be someone who runs a team that looks high-performing on paper.
Because their output is visible, leaders convince themselves they can’t afford to lose them. They tell themselves things like:
We can’t replace that level of performance.
This would create too much disruption.
Maybe I can coach them through it.
Maybe it’s not as bad as it seems.
Now isn’t the right time.
Over time, many leaders start to feel almost held hostage by this person. The high performance is real, and that makes it easy to leave everything else in the blind spot.
That’s usually where the problem starts. And that cost is usually bigger than it looks.
What leaders often miss
When leaders think about a brilliant jerk, they focus on what that person contributes. What they miss is what that person is quietly costing the organization.
Sometimes the damage is obvious. Morale drops. People complain. Tension becomes visible. But often, the more serious damage is harder to spot while it’s happening.
They create dysfunction on teams.
When someone is dismissive, rude, overly confrontational, or just difficult to work with, other people start adjusting around them. They speak up less. They avoid conflict. They stop bringing things to the surface as directly as they should.
What looks like team dysfunction is often one person making it harder for everyone else to fully participate.
They slow down decisions.
When people start avoiding one person, decisions get harder. Conversations happen outside the room instead of in the room. Alignment takes longer. Important issues surface later than they should.
The organization gets slower. Not because the team lacks talent, but because one person has made honest collaboration harder than it needs to be.
They limit the people around them.
This is one of the most overlooked costs. A brilliant jerk can lead a team that appears to be performing well while that team is actually operating below its potential.
People underneath them spend energy managing the relationship, staying out of the way, or absorbing the disruption. Once that person is gone, other leaders step up. The team gets healthier. Performance improves.
What looked like irreplaceable talent turns out to be a bottleneck.
They push good people out.
Sometimes people leave because of a toxic leader or teammate and never say that’s the reason. They’ll say they found another opportunity. They’ll say the timing was right. They’ll say they were ready for something new.
But often, they were simply tired of working around someone who made the environment harder than it needed to be. When good people start leaving quietly, the cost of tolerating bad behavior adds up fast.
What to do when you have a brilliant jerk
The most important thing you can do is stop delaying. That doesn’t mean jumping straight to firing them. It means taking the issue seriously enough to address it clearly and quickly.
Here’s where to start.
1. Get specific about the behavior.
Before you confront the issue, get clear on what is actually making them a problem. Don’t rely on vague labels like “difficult” or “not a culture fit.”
Ask yourself: What behavior keeps showing up? What patterns are recurring? What impact is it having on the team? Who is being affected? How is it changing trust, performance, or decision-making?
The clearer you are, the better the conversation will go.
2. Confront the behavior directly.
This is the part most leaders avoid. Be direct about what you’re observing, why it’s a problem, what impact it’s having, and what needs to change.
If this is the first serious conversation, treat it as feedback and coaching. If you’ve already had multiple conversations and the behavior continues, you’ve moved past coaching.
At that point, you’re not raising a concern. You’re addressing a behavior that requires real change.
3. Put expectations in writing.
This is where many leaders stay too casual for too long. If the issue is serious, document it. Put in writing the behaviors that are unacceptable, the behaviors you expect instead, the timeline for improvement, how progress will be evaluated, and what happens if change does not occur.
Writing it down creates clarity. It also signals seriousness. If you want the person to understand this is a turning point, this step matters.
4. Watch for real signs of change.
When a high performer has truly heard you, you usually see signs quickly. Not perfection, but progress.
You see them taking ownership and demonstrating a willingness to change.
If instead you see defensiveness, blame, or no real shift in behavior, that tells you something important.
5. Be willing to act.
If the behavior doesn’t change, you have to make the hard call. That might mean helping them make a dignified exit. That might mean moving them out of a leadership role. That might mean ending the relationship entirely.
Whatever the path, the principle is the same. If they are unwilling to change, their performance is no longer enough.
Keeping someone because they are productive is not leadership. It’s avoidance. And everyone around them pays the price for it.
Remember who is counting on you
The CEOs I’ve worked with who have finally dealt with a brilliant jerk say the same thing afterward, “I wish I hadn’t waited so long.”
Every time.
Part of why they waited is the same reason you might be waiting. They thought they could manage it. They focused on what it would cost to act and stopped thinking about what it was already costing to wait.
But here’s what’s easy to forget.
If you are struggling with this person, and you’re their boss, imagine what it’s like for the people who report to them. The people who have no leverage. The people who are likely on their best behavior with you while absorbing something much harder every day.
They are waiting for you to do something. They may never say it directly. But they are counting on you to protect the environment they work in.
When you finally act, something shifts. The tension breaks. Energy comes back into the room. People who had been holding back start to show up differently.
That is what’s on the other side of the decision you’ve been putting off.
