A chief operating officer told me last spring that his leadership team had not lost a single member in four years, and he offered it the way you would hand over a clean audit. The same faces around the table that were there before the last reorganization, before the board started asking about AI in every review, before half the industry restructured around it. He meant it as proof he had built something people did not want to leave. I asked him who below that table was ready to sit at it, and the room went quiet in the particular way rooms go quiet when the honest answer is nobody, not yet.

That silence has started showing up in the numbers. LHH, the talent-solutions arm of the Adecco Group, surveyed more than 2,500 companies at the end of 2025 and found that the share of organizations with high executive churn, defined as more than half the leadership team turning over, fell from 43 percent to 19 percent in a single year.1 Almost sixty percent of late-career executives said they have no plans to leave within three years, up from eleven percent a year earlier.1 It helps to know who is holding the clipboard, because LHH sells the succession and career-transition services the report says companies now urgently need, so the alarm works in their favor. Even with that discount applied, the pattern holds. A board reads those numbers as retention. What they measure is a top that has stopped moving, and that changes what happens to everyone underneath it.

Stability and stagnation can wear the same face

Promotions in most organizations work like a parking structure with one exit. The senior spots open when the people in them leave, and everyone below arranges their patience around that assumption. When the exits close, the wait stops being temporary. The high-potential director who was three years from a vice-president seat is now told, without anyone quite saying it, that the seat is occupied indefinitely. She runs the math faster than the executive above her does. LHH found that almost half of the Gen Z leaders it surveyed named limited advancement, the inability to broaden their scope or grow their skills, as the main reason they would consider leaving.1 So the same freeze that keeps the top comfortable pushes the people who were supposed to replace them toward the door first. The organization loses its future before it notices its present has calcified.

Why staying has never looked smarter

None of this makes the executives villains. Read the rest of the LHH data and the choice to stay looks entirely rational. Economic uncertainty was the concern those same leaders rated highest, and close to half named AI and emerging technology among their top priorities.1 When the ground is moving that fast and your own fluency with it is suddenly in question, the safe play is to hold your position and wait for clearer weather. The trouble is that the aggregate of all those sensible individual choices is an organization that can only change direction by waiting for people to age out of it. Brad Jayne, a principal at Pearl Meyer who co-authored a separate 2026 survey of executives and directors, points to finance and insurance, the fields where people tend to hold their seats the longest, as exactly the places where it is hardest to move the needle.2 Those are the same places that will tell you, proudly, that their leadership has been stable for fifteen years.

Why the succession binder fails

Most organizations answer this with a document. A nine-box grid, a list of names under a heading that says ready in one to two years, a folder that gets opened when someone actually resigns. That folder is close to useless, because readiness cannot be assigned from a grid. People build it by doing the work before the title arrives, and only if someone above them hands over decisions they have been keeping for themselves.

When the same people hold the same seats for a decade, an organization slowly forgets how to replace anyone. The day it finally has to, it discovers the skill was never built.

The work of succession is not annual. It is what a leader does on a Tuesday when a hard call lands on the desk and, instead of making it, hands it to the person who will eventually inherit the desk and coaches them through getting it wrong. That is expensive in the moment, and it is the only thing that builds a bench. A leader who never does it can stay in the role for twenty years and leave nothing behind but a vacancy.

There is a particular hubris that settles into founders and long-tenured chief executives, a settled assumption that they will always be the one in the chair. Jamie Dimon has run JPMorgan for the better part of two decades, and the question of who succeeds him has become a standing story in its own right. The assumption is flawed however it plays out. A leader who never resigns and never loses the board still runs into time in the end, and for some it arrives far sooner than they planned. So the work is to name the one or two people who could take your seat early in your tenure rather than late, and to start pulling them into the conversations their current role does not yet require, so that they are thinking a level up long before they need to.

Years ago I watched five civilian contractors take over a threat picture in a combat zone and bring hostile incidents down from more than eight hundred a month to under fifty inside a year. Not one of them outranked anyone. What changed was that the people closest to the work were handed the authority to act on it rather than routing every judgment call up the chain. Renewal did not wait for anyone at the top to vacate a seat. It started the moment ownership moved down. I wrote about that year, and what it taught me about giving accountability away on purpose, in Agile Sucks! (When You Do It Wrong), the book James Wright and I wrote for leaders who suspect their own structure is the thing holding them in place.

Let me say it more plainly than the research will. Preparing the people who could replace you is the most important work you do in any leadership role. Everyone who reports to you should be able to do your job, and on the day you leave, one of them should be ready to step into it. Build that and you have built something that outlasts you. Leave behind an organization that falls apart the moment you walk out, or a seat no one else can fill, and whatever you were doing in that role, it was not leadership. Leaders create leaders. That is most of the job, and it is the part a frozen top has stopped doing.

So the question worth sitting with is a plain one. If you stepped out of your role at the end of this year, is there someone in your organization who could take it, or have you built a table that only works with you at the head of it?
