The Relevance Migration

Walk through your office, your clinic, your shop floor. Count the people who are physically present. Now ask a harder question: how many of them are actually still there, fully invested in the work in front of them, versus quietly present while some part of their attention has already relocated somewhere else? That gap between physical presence and full engagement is the earliest, quietest signal of what I call Relevance Migration, and it’s reshaping the workforce far faster than most leaders have noticed.

Here’s the core idea. Talent doesn’t disappear when it becomes disengaged. It migrates. A skilled employee who feels increasingly irrelevant in their current role doesn’t necessarily quit outright. More often, they start mentally relocating, exploring adjacent fields, absorbing new skills on the side, quietly testing whether their expertise might be more valued somewhere else entirely. By the time they formally resign, the migration has usually been underway for months. The resignation is just the paperwork catching up to a decision the person already made internally.

Leaders often talk about losing good people as though it happens suddenly, a shock resignation nobody saw coming. In reality, it rarely works that way. Career switchers, people who intentionally leave one field for another, don’t wake up one morning and decide to abandon everything they know. Recruiting research increasingly frames these switchers as some of the most valuable hires available precisely because they’ve already demonstrated the ability to learn new systems quickly, adapt to unfamiliar environments, and apply existing skills in contexts nobody trained them for. That kind of readiness doesn’t appear overnight. It builds slowly, while the person is technically still on your payroll.
