The data that got my attention
Gallup’s 2026 State of the Global Workplace report finds global manager engagement at 22% in 2025, a nine-point drop since 2022 and a five-point drop in the single year between 2024 and 2025. At the same time, best-practice organizations report 79% manager engagement — nearly four times the global average. The gap is not a regional accident; it is a design choice.
A 2025 computational model published in the American Journal of Preventive Medicine puts the annual burnout cost at $10,824 per manager and $20,683 per executive. Apply those figures to a 1,000-person company and the tab reaches roughly $5.04 million every year. That makes the 79% benchmark more than a morale story; it is a financial target.
Why this matters now
Managers sit between strategy and execution. When their own engagement collapses, the buffer that translates executive intent into daily work disappears. Gallup attributes about 70% of team engagement variance to the manager alone, so a burned-out manager is not one person’s problem; it is a team-wide risk.
SHRM research puts the cost of replacing an employee at 50% to 200% of annual salary. For a manager earning $100,000, the organization can spend $50,000 to $200,000 on recruitment, onboarding, and lost productivity before a replacement becomes fully effective. When burnout pushes several managers out at once, the cost compounds faster than most succession plans assume.
Organizations are flattening structures and adding AI pilots at the same time, which widens spans of control. Gallup data show the average manager’s span grew from 10.9 direct reports in 2024 to 12.1 in 2025, and 13% of managers now lead 25 or more people. The job has expanded faster than the support around it.
What the research actually shows
The table below summarizes the most relevant findings from Gallup, DDI, and peer-reviewed research.
| Metric | Finding | Source |
|---|---|---|
| Global manager engagement | 22% in 2025; down 9 points since 2022; down 5 points in the single year 2024-2025 | Gallup State of the Global Workplace 2026 |
| Best-practice manager engagement | 79% of managers engaged, nearly four times the global average | Gallup State of the Global Workplace 2026 |
| Team engagement variance tied to manager | Approximately 70% of team engagement is attributable to the manager | Gallup manager effectiveness research |
| Global economic cost of low engagement | About $10 trillion in lost productivity, or roughly 9% of global GDP | Gallup State of the Global Workplace 2026 |
| Annual burnout cost per manager / executive | $10,824 per manager; $20,683 per executive; $5.04M per 1,000-employee company | American Journal of Preventive Medicine, 2025 |
| Average manager span of control | 10.9 direct reports in 2024 to 12.1 in 2025; 13% of managers lead 25+ people | Gallup span of control research, 2026 |
| Leaders reporting increased role stress | 71% of leaders say stress has increased since stepping into their current role; 40% considered leaving | DDI Global Leadership Forecast 2025 |
The final rows matter most. The collapse is not inevitable. Organizations that redesign the manager role can reach 79% manager engagement, almost four times the global average.
A practical framework for leaders
Stop treating burnout as a wellness perk. Treat it as a capacity problem. Leaders can start with three concrete steps.
- Audit manager workload. Map how managers actually spend their hours. If individual-contributor work still consumes a large share, the team will not scale and managers will keep burning out.
- Right-size spans of control. Most managers can lead 8 to 10 people well. Past 12 direct reports, reduce personal production targets and install stronger delegation systems.
- Build people skills deliberately. Emotional intelligence, coaching, and delegation are the skills that keep managers effective as their teams grow. Track them as business metrics, not training checkboxes.
Run a pilot with the highest-risk managers. Measure engagement, retention, and productivity before and after the changes. Use that evidence to justify wider rollout.
The bottom line
Manager burnout carries a measurable price tag: lower engagement, higher turnover, and wider productivity loss. The organizations that fix it do so by redesigning the manager role, not by sending exhausted managers to another resilience webinar.
Where to go from here
Start with an honest assessment of where manager capacity is breaking. Map workload, span of control, and the people skills your managers need most, then build a targeted development plan for the managers carrying the heaviest load. executive coaching →
