Meet Scott. He’s a regional sales director, forty percent above quota, the guy leadership calls when a deal is collapsing. The board knows his name. His comp package has been quietly restructured twice just to keep him from taking outside calls. 

Scott also arrives late to meetings and leaves early. He dismisses colleagues’ ideas in front of the whole team. He takes credit for collaborative work. He ignores the new performance review system entirely, and when his manager, Janet, raises it, he just smiles: “Come on, Janet, these things really aren’t for guys like me.” She laughs. She hates that she laughed. 

Meanwhile, three talented teammates are quietly job hunting. One has already accepted an offer elsewhere. Morale is down. Collaboration has gone transactional. Everyone sees it. Nobody’s said anything yet. 

What We Actually Mean by “Toxic” 

That word gets thrown around too loosely these days — honest feedback, high standards, an ordinary hard conversation all get labeled toxic, and I think that overuse lets us avoid asking what our own part in the friction might be. 

So let’s be precise. We mean sustained patterns: treating people’s time and dignity with contempt, violating the norms an organization is trying to hold, causing measurable damage to morale and retention — and doing it despite feedback. Someone who behaves badly but genuinely changes when confronted isn’t who we’re talking about. We’re talking about someone who, when confronted, denies, minimizes, or hides behind their own results. 

Three Things Happening Underneath 

Bowen family systems theory gives us a useful lens here, and three concepts show up clearly in Janet’s situation: 

• Togetherness pressure — senior leadership’s collective belief that Scott’s numbers outweigh his behavior makes any action against him feel dangerous. 

• Distancing — Janet is avoiding both Scott and the consequences of his behavior. It feels safer. It resolves nothing. 

• Differentiation of self — the real fix isn’t a better Scott. It’s a more defined Janet, someone who can stay grounded and clear even while the system around her pushes her to back off. 

The toxic star problem, at its core, is a differentiation problem in the leader, not primarily in the star. 

The Cost of Looking Away 

Systems-based coach John Engels has found teams with a toxic star see thirty to forty percent higher turnover — a cost that almost always dwarfs whatever revenue the star generates. (I’ve sat through enough of these conversations in HR to know the math never gets run early enough.) Engels also names the rationalizations leaders reach for: the client loves them, they make us money, nobody else has their expertise. Real concerns. But they function as excuses, not reasons. 

What a More Grounded Leader Actually Does 

A few practical moves, borrowed loosely from Engels and from Bowen: 

• Get objective — name specific behaviors, not vague impressions (“arrives late,” not “is difficult”) 

• Anchor expectations to standards and values, not personalities 

• Quantify the impact — turnover numbers, exit interview themes, real costs 

• Give direct feedback that holds both truths: “Your results are strong, and how you’re operating is damaging the team” 

• Build accountability that sustains itself — document, measure, follow through, and have both a stay strategy and a leave strategy ready 

The Real Question 

This isn’t easy. It means tolerating Scott’s reaction — the deflection, the charm, the anger — without backing down. It means holding the line when the CEO reminds you for the third time what his pipeline looks like. 

But the team is watching. They’re wondering if anyone’s going to do anything. And as executive John Ingalls puts it, a talented person’s real value isn’t just their individual output — it’s how they elevate the whole team. A toxic star might shine bright in the short term. Over time, they cast a long shadow. 

The strongest organizations choose culture over chaos. That starts with a leader who knows what she stands for — and is willing, when the moment comes, to stand there.
