Every organisation has lost someone it was sure was happy. Those exits are not random, and they are not invisible — they are simply not in the data most companies collect.
A resignation feels sudden when the signal that preceded it was not being collected. Engagement data captures dissatisfaction well — and dissatisfaction is only one of the two routes people take out of an organisation.
The other route produces no complaints at all. Someone who is committed, absorbs load, and never raises a problem is not sending a signal an engagement survey can read. The absence of complaint is often mistaken for the absence of a problem.
Committed people who ran out of resource. They rarely complain, because complaining is not what committed people do, and they leave for a lateral move rather than a promotion — the clearest sign the work itself stopped being affordable.
People who lost purpose, trust or a path forward. This is the route engagement surveys detect well, and the one most retention programmes are designed around.
The two need entirely different responses. Offering development to a depleted person adds load; reducing load for a disconnected person changes nothing. Which is why a single retention-risk score is close to useless.
Capacity measures whether people have the physiological and cognitive resource to sustain their contribution — energy, recovery, focus and resilience, scored 0–100 each. It is the half that detects route one.
Measured alongside engagement in the same window, it separates the two populations before either becomes an exit. A team with high engagement and falling recovery is not a healthy team; it is a retention risk that has not surfaced yet.
How depletion presents in people who never complain: committed but depleted.
Recovery moves earliest. On the disconnection route, Growth & Enablement is usually the leading signal — people conclude there is nowhere to go before they conclude they should leave.
Note the bases differ: the retention figure compares strongest against weakest enablement, the advocacy figure bottom against top decile of the Thrive Index. They are not interchangeable, and we would rather say so than present them as one scale. Retention here is a score, not a record of who left.
The instrument, cadence and thresholds: the Employee Capacity Survey. How results become action plans and matched learning: the platform.
Figures come from thrive at work’s own validation study (n=10,000+, 2025–26), fielded across the US and Europe. Each comparison states its own basis — decile or quartile — and they are not interchangeable.
These are associations measured within a single cross-sectional study, not causal claims. No score is displayed for any group of fewer than five people.
