London Business School professor Lynda Gratton was advising a global company's leadership team when its chief executive stopped mid-conversation. "We have a problem," he told the room. "Burnout is becoming a real issue." The employees struggling the most weren't the newest hires or ones nearing retirement. They were mostly in their mid-40s to early 50s.
Many were the company's strongest performers, already being groomed to run the place, but instead of advancing, they were losing steam. The company watched its leadership pipeline stall at exactly the moment it needed those people most.
The usual response to that kind of exhaustion is to tell people to build more resilience. Gratton's diagnosis is more broad-based. People in their 40s and 50s stall, Gratton argues in Harvard Business Review, because the job treats them like they're near the finish line of a 30-year career when they're actually only about halfway through one that will run 50 or 60 years. Nobody redesigned the job, the promotions, or the expectations to match the extra decades.
The mismatch that appears in your 40s
Gratton calls this stretch of a career the "pivotal 40s," the years when someone carries the most responsibility they'll ever hold and has the least space to step back and think about any of it.
A 10-week pilot program she ran with 20 midcareer and senior professionals from three companies in France, Sweden, and the U.K. tested that pattern directly. People in their 40s posted the weakest scores of any age group on what Gratton calls "calm," the capacity to pause and reset. The decade that most needs a clear head is the same decade that leaves the least time to find one.
A division head in their 40s, pressed to react rather than reflect, ends up in permanent fight-or-flight. Reactive calls at that level drag other people's budgets and careers along with them. A wrong one compounds through the organization in ways that would have faded 10 years earlier.
Those consequences push people in their 40s into a harder question than whether they're performing well. Gratton's participants found themselves asking whether they were even in the right place. A question like that takes real time to answer honestly, and the job that created it is also the job that crowds out any chance to sit with it.
Understanding a role's true parameters
One biotech CTO profiled in Harvard Business Review found after a year-and-a-half of fighting fires that she was ready to quit and retire early. Her story is common at the top. Deloitte found that close to seven in 10 C-suite leaders have seriously weighed walking away from their jobs to protect their mental health.
Executive coach Darcy Eikenberg, along with leadership advisor Tony Martignetti, has learned that adversity in many senior roles never lets up. Almost all of these leaders have to either endure the role or leave it. Most quit before ever discovering how much of what exhausts them was simply inherited from the last person in the seat.
Eikenberg's fix is a self-directed exercise she and Martignetti call a Personal Retention Plan, which tests what a role actually requires before anyone assumes the only choices are enduring it or leaving.
One commercial leader she coached had already ruled himself out of his company's CMO job over the punishing travel schedule kept by the current executive. "I couldn't do what Jonathan does," he admitted. "He's on the road three weeks a month and works 24/7. With my kids in school sports, I couldn't do that. Correction — I don't want to do that." Working through the exercise, though, he found that persistent travel was purely a habit of the person in the role. He ended up putting his name forward instead of walking away.
Two fixes for the same issue
Gratton's answer redesigns the job from the organizational side. One move is to build real reflection time into the role. Think of a midcareer review that weighs long-term direction as seriously as performance, or a sabbatical baked into the calendar before anyone hits a wall. Another is to stretch people inside the role they already hold, through cross-functional work or reverse mentoring, so growth comes from the job itself.
A third move normalizes lateral shifts and skill pivots as a routine part of a long career. Right now, most career changes only happen after burnout or frustration forces the issue. Treating a sideways move as reinvestment gives someone a way to change course before leaving feels like the only option.
Gratton's fixes reshape the structure around a person. The Personal Retention Plan changes the person's relationship with the role they already hold. A company serious about keeping its midcareer leaders needs both running at the same time, because the structural change takes years to land and the person sitting in the seat today needs an answer now.
That commercial leader is still years from learning whether the CMO job fits him the way he redesigned it. Every company with a stalling leadership pipeline now faces the same question he did: whether the role should look the way it's always looked, or the way it needs to look for someone with 30 years of career still ahead of them.
