Count the full cost of a “star” and handle a conversation about behavior with your strongest performer.
The strongest, and the most expensive
The full cost of a star
The strongest engineer, the best numbers — and his comments make juniors cry, while a mid-level engineer left “for personal reasons.” The mistake is counting only his contribution.
Full cost = the star's contribution minus the losses around him: silence in meetings, ideas never voiced, turnover, your hours spent smoothing things over. The team doesn't look at the written rules; it looks at what you tolerate: tolerating a star's rudeness announces that rules are for the weak.
The conversation is the same SBI, with no discount for genius: facts about behavior, the impact on people and the work, a boundary: “Your expertise is valuable. Results don't buy the right to humiliate people. We have one standard of conduct for everyone.” And consequences if it happens again — ones that will actually happen: an empty threat is worse than silence.
Important: a fair chance first. Many stars haven't heard direct feedback in years — everyone was afraid. Often there's exhaustion behind the harshness: the star fixes everyone else's work and is angry about it.
“Irreplaceability” has one test: your willingness to part ways. After a toxic star leaves, teams more often breathe a sigh of relief and grow than fall apart.
The visible and the invisible
| Visible contribution | Invisible losses |
|---|---|
| Handles the hardest tasks | Juniors are afraid to ask questions |
| The best numbers on the team | A mid-level engineer left, giving a neutral reason |
| Fast solutions | Other people's ideas never get voiced |
| Expertise for the whole team | Your hours spent smoothing things over |
