In looking for people to hire, look for 3 qualities: integrity, intelligence, and energy. And if they don't have the first, the other two will kill you.
Hi friends! 👋
Every Friday, I'm answering one real question from a real leader. No theory. No fluff. Just the stuff you're actually dealing with.
If you've got a question you'd like me to tackle, just hit reply. I read every one.

This week’s question comes from Denise:
I manage a high performer who produces exceptional work but is genuinely toxic to the rest of the team. Morale visibly drops when they enter a room. At what point does the talent no longer justify the collateral damage?
Denise, I want to give you the answer up front.
You're past that point already. The fact that you wrote this email is the proof.
But let me show you why, because the math on this surprised even me.
The star the executives loved
Earlier in my career, I worked under a leader the executives adored.
Polished. Charming. Brilliant at managing up.
From above, he looked like a superstar.
Inside the team, the story was different. He led from insecurity. Pushed people down to feel bigger.
The execs thought he walked on water. We were just trying to survive the week.
Somebody above him was running your exact calculation, Denise. The output looks exceptional. The damage seems manageable.
It took years for the truth to catch up to him. When he was finally forced out, the whole team exhaled like we'd been holding our breath the entire time.
That experience taught me something I've carried into every leadership role since.
Output flows up. Damage flows down. The person deciding the toxic star's fate sees the least of the harm.
You're already seeing the harm, Denise. That puts you years ahead of the leaders who kept him.
Harvard did the math on your exact question
Researchers Michael Housman and Dylan Minor studied over 50,000 workers across 11 companies to answer one question. Which is worth more: landing a superstar or avoiding a toxic worker?
The results weren't close.
A top 1% superstar adds about $5,303 in value.
Avoiding a single toxic worker saves about $12,489. More than double.
And that figure only counts the turnover they cause. Add litigation risk, lost morale, and the ideas people stop sharing, and the gap widens.
One more finding from the same study, and this one matters most for you.
Toxic workers tend to be MORE productive than average. That's how they survive. The output buys them cover.
Which means your situation has a name in the research. You're not weighing talent against damage. You're holding the exact profile the data warns about.
So let me give you the playbook.
1. Run the full ledger
Take 15 minutes. Two columns.
Left side: what they produce. Right side: what they cost. The hours you spend mediating. The people eyeing the exits. The ideas your team stopped voicing. The meetings that die when they walk in.
Most leaders only ever count the left column. The right column is where the real money is.
2. Name the behavior in specifics
Vague feedback bounces off high performers. They'll point at their numbers every time.
So get concrete. "In Tuesday's meeting, you cut Sarah off 3 times and called her proposal a waste of time. That's the pattern we need to talk about."
Make it clear that behavior is part of performance. Production was never the whole job.
3. Set a real timeline with real consequences
One honest coaching conversation. Specific behaviors, specific expectations, a specific date.
Some people truly don't see their impact. Give them one chance to prove they can change once they do.
But put it in writing. And mean the date.
4. Decide who you're willing to lose
You will lose someone. The only question is whether you choose who.
Keep the toxic star, and your best people decide for you. Quietly. One transfer request at a time.
One more thing, Denise.
A few days ago I posted 16 signs of a toxic leader on LinkedIn. Over 350,000 people have seen it. Hundreds shared their stories in the comments.
Sign #11 got a lot of attention: they tolerate disrespect and abuse.
Almost everyone reads that list scanning for their boss.
The brave ones read it scanning for themselves.
Because the team is watching this situation closer than you think. Every week the behavior goes unaddressed, it’s teaching them what the standards actually are. Tolerance reads as endorsement.
I run my own company now. The first standard I hold myself to came from those years: protect the culture. When toxicity shows up, act right away.
So this week: run the ledger. Have the specific conversation. Set the date. And decide who you're willing to lose, before the decision gets made for you.
The exceptional work was never free. You've just been letting other people pay for it.
Until next time, keep being brilliant,
Justin
