Understanding Why Top Performers Quit After Their Biggest Wins
When a top performer hands in their notice, the immediate reaction for many organizations is to search internally for reasons. Questions like, “Why do high performers leave?” or “Why did my best employee quit right after a major achievement?” often lead leadership to focus on familiar factors such as compensation, company culture, management style, or growth opportunities. While these can sometimes play a role, emerging research highlights a less obvious, yet critical, pattern that many organizations overlook — one that occurs right after a significant success.
This pattern, sometimes referred to as the “success crash” or post-achievement depression, is a biological response rather than a management failure. It tends to strike those who have just delivered their best work, at the very moment when everything appears to be going well on paper. Understanding this phenomenon is crucial for organizations hoping to retain their highest-performing talent.
The Neurochemical Rollercoaster Behind Success
In the months leading up to a major goal, top performers’ brains are fueled by a powerful cocktail of neurochemicals: dopamine, adrenaline, and cortisol. Dopamine propels the pursuit of rewards and accomplishments, adrenaline sharpens focus and readiness, and cortisol helps sustain pressure over extended periods. This finely tuned neurochemical blend enables top performers to operate at exceptional levels, often producing up to 400% more output than average employees, according to research cited by Google and HRBench.
However, once the goal is achieved, these neurochemicals drop rapidly. The dopamine that fueled anticipation vanishes as the target disappears, adrenaline levels fall, and cortisol decreases. This fast decline triggers what researchers call post-achievement depression or the “success crash.” Far from being mere disengagement or loss of motivation, this is a biological comedown that affects the very people who pushed hardest to reach the finish line.
National Institutes of Health research on burnout and the hypothalamic-pituitary-adrenal (HPA) axis illustrates that chronic stress leads to elevated cortisol followed by exhaustion and suppressed function. The system that kept top performers at peak capacity doesn’t simply switch off once the goal is met — it leaves them vulnerable to a state of depletion.
Why the Best Employees Are Most at Risk
Contrary to common assumptions, it’s not the struggling or less engaged employees who are most likely to experience this crash — it’s the high achievers. These individuals often tie their identity closely to their work performance and have invested significant emotional and physical energy into their success. When the goal disappears, so does the neurochemical “calibration” that kept them in high gear.
The typical organizational response — to celebrate the win but immediately assign a new high-pressure project — can inadvertently worsen the situation. Instead of building momentum, this approach removes the crucial recovery window, resulting in accelerated burnout and eventual disengagement.
The implications are not just about retention. The World Health Organization estimates that in a company of 1,000 employees, one worker dies by suicide every 10 years, with many more attempts occurring. Management occupations, where many top performers reside, have the highest share of workplace suicides. This stark reality underscores that these challenges affect driven, capable individuals lacking the tools to safely “come down” from sustained high stress.
The Hidden Costs of Missing the Post-Win Crash
Losing a top performer is expensive — at least three times their annual salary when considering recruitment, onboarding, lost productivity, and institutional knowledge. Yet, the more significant loss is often invisible. When high performers quietly disengage before resigning, organizations lose their driving force while key performance metrics may still appear stable. Teams sense the void long before leadership acts, and by then, the top talent is often halfway out the door.
Research shows that up to 75% of voluntary departures are preventable, yet most retention strategies begin too late and look in the wrong direction. Few consider the timing of departures relative to major wins, missing a crucial opportunity to intervene effectively.
Building a Plan for What Comes After the Win
Organizations that successfully retain top talent through high-output cycles understand they must do more than offer perks or promotions. They create a deliberate plan for the post-win period that acknowledges and addresses the biological realities of the success crash. This plan includes three essential components:
- Awareness: Leaders and executives need to recognize the post-achievement crash, understand its internal experience, and identify the employees most vulnerable — often their highest performers. Without this foundational knowledge, any intervention is guesswork.
- Structured Recovery Window: After every major win, there should be an intentional recovery period ranging from 48 hours to seven days. During this time, expectations shift from acceleration to integration. This is not a vacation or a performance review but a guided process centered around three reflective questions: What did this cost you? What part of this achievement truly mattered? What do you need before you can fully re-engage? Each top performer’s response will differ, highlighting the need for personalized support rather than one-size-fits-all policies.
- Guidance Through the Process: Employee retention starts with leadership, but leaders themselves must be equipped to recognize and manage these cycles. Managing energy and recovery after a major finish is a skill, not just a wellness initiative. Support from someone who can help employees navigate their recovery is crucial to prevent burnout and foster sustained engagement.
Top performers are not leaving because of poor leadership or inadequate rewards alone. They leave because no one helped them understand or manage the biological cost of their achievements. By acknowledging this and implementing thoughtful post-win strategies, organizations can reduce turnover, protect their best talent, and maintain high performance over time.
