Gallup's 2026 State of the Global Workplace landed last week with a number that belongs in every succession conversation. Global manager engagement has fallen from 31% in 2022 to 22% in 2025 — a nine-point drop, with five of those points lost in a single year.

Gallup's analysis is blunt: lower manager engagement is now driving most of the overall decline in global employee engagement. Most CHROs will file this under "management development priorities."

The sharper reading: your managers are the first tier of your succession bench. Their disengagement is not a sentiment problem. It is a succession early-warning signal — and it is almost certainly not visible on your succession grid.

Here is a pattern that shows up in almost every organisation I work with.

Two processes. Two rooms. Zero connection.

In one room: the engagement survey cycle. Data collected, scores analysed, action plans drafted, line managers briefed, targets set for next year.

In the other room: the succession calibration. Readiness ratings reviewed, bench maps updated, grid discussions held, nominations confirmed.

The same leaders appear in both. Almost no organisation connects the two datasets.

That disconnect has three specific consequences:

Disengaged high-potentials are succession gaps in formation. When a succession-ready leader starts disengaging, the conventional HR response frames it as retention risk — a people issue for their manager to resolve. The succession response asks a harder question: if this person leaves next quarter, can you name their replacement and explain the evidence to the board? If the answer is no, the disengagement data was carrying a succession risk signal that nobody read.

Engaged successors in fragile teams are misleading signals. An engaged high-potential in a stable, well-led team looks ready on paper. The same candidate managing through sustained pressure, operating through ambiguity, leading through a restructure — reveals something very different. Engagement data connected to team-level performance data tells you which successors have been stress-tested and which have only ever been observed in favourable conditions.

Manager disengagement is bench collapse in slow motion. Managers are the data collection point for every talent conversation that feeds a succession grid. When manager engagement collapses — as Gallup's data shows it has — the quality of talent intelligence falls with it. Performance ratings become less differentiated. Talent conversations get shorter and less rigorous. HiPo nominations shift from evidence to politics. The bench looks full on paper. The underlying data quality is gone.

These three patterns are not theoretical. They appear every time the intelligence layer is properly assembled. Most organisations do not see them because the datasets are never connected.

When I'm working with a client on this, I use the Engagement Intelligence Model alongside performance and succession data. The model connects three layers: engagement score at individual and team level; performance trajectory over time (rising, stable, declining); and succession readiness rating from the last calibration.

The output is not a satisfaction report. It is a risk matrix that identifies where disengagement and succession risk are coinciding in the same people — and where successors are being rated as ready without the team-level context that would challenge that rating.

Running this model across 30 countries surfaced three high-potential leaders rated "succession-ready" in the formal calibration process whose engagement trajectory over 18 months told a very different story. One had already mentally resigned. Two others were misread because their strong individual scores were masking fragility in the teams they were managing.

The intelligence layer doesn't change the calibration. It changes the quality of the conversation. (totalia framework)

Gallup 2026 State of the Global Workplace — Manager engagement has fallen nine points in three years, and Gallup's analysis shows this is now driving most of the overall decline in global employee engagement. The succession implications are not discussed in the report — but they should be.

BCG Creating People Advantage 2026 — 65% of senior leaders now view HR as a key business driver, yet 51% cite administrative load as the primary barrier to strategic contribution. Worth reading if you are building the case for a talent intelligence function rather than a talent operations one.

Edition 2 — If your COO resigned today, what would you tell the board? — The succession risk edition. This week's engagement argument sits directly on top of it: the succession conversation becomes much harder when your engagement data is already telling you someone might not be there in six months.

If this landed for you — send it to one CHRO, CPO, or CEO in your network who is running an engagement programme and a succession process as two entirely separate things.
