The data that got my attention
Deloitte’s 2025 Global Human Capital Trends report finds that nearly 40% of a manager’s day is eaten up by firefighting today’s problems or completing administrative work. Only 13% of that same day goes to developing the employees who report to them. That imbalance is not a time-management problem. It is a structural one.
The survey, which included nearly 10,000 business and HR leaders across 93 countries, also found that 36% of managers feel they are not sufficiently prepared for the people-manager parts of their role. Worse, 40% of managers report a decline in mental health after becoming managers. The people charged with leading teams are starting the job already behind.
Why this matters now
Organizations are asking managers to absorb AI adoption, return-to-office debates, and continuous transformation at the same time. Each of those initiatives creates new work. Few of them remove old work. The result is a capacity crisis at the exact layer of the organization that determines whether strategy becomes execution.
Gallup’s 2026 State of the Global Workplace report confirms the consequence. Lower engagement among managers accounts for most of the recent downturn in employee engagement. When managers are overwhelmed, the teams they lead feel it first in delayed feedback, unclear priorities, and weaker coaching. The damage shows up later in turnover and missed targets.
What the research actually shows
The latest workplace data paint a consistent picture across sources.
| Source | Finding | Business impact |
|---|---|---|
| Deloitte 2025 Global Human Capital Trends | Nearly 40% of manager time goes to firefighting and admin tasks; only 13% goes to developing employees. | Managers are paid to lead people but spend most of their time on work that does not build team capability. |
| Gallup State of the Global Workplace 2026 | Manager engagement fell from 31% in 2022 to 22% in 2025, a nine-point drop. | The people accountable for team engagement are now only as engaged as the employees they lead. |
| Gallup best-practice organizations 2025 | 79% of managers are engaged in top-performing organizations. | The gap between average and high-performing organizations is now nearly fourfold. |
| Eagle Hill Workforce Burnout Survey 2025 | 55% of U.S. workers report burnout; 72% say it hurts their efficiency. | Burnout is a performance and retention problem, not a wellness perk. |
| Eagle Hill 2025 | Of burned-out workers who tell their manager, 42% say the manager takes no action. | Employees are raising the flag, but managers often lack the bandwidth or authority to respond. |
This is not a single-source story. Deloitte, Gallup, and Eagle Hill are all pointing to the same issue: the manager job has expanded faster than the support around it. When 40% of the role is consumed by low-impact tasks, there is little left for the work that actually improves teams.
A practical framework for leaders
Fixing overwhelmed managers requires redesigning the role, not just sending them to another resilience seminar. CEOs and senior leadership teams can start with three concrete moves.
- Audit the manager workload. Track how managers actually spend their hours for two weeks. If individual-contributor work, reporting, and firefighting consume more than half of the week, the team structure needs to change before any leadership training can work.
- Right-size spans of control. Gallup finds that manager engagement declines as teams get larger. Most managers can coach and develop 8 to 10 people well. Beyond 12 direct reports, managers need lighter production targets, stronger delegation systems, or additional team leads.
- Build people skills deliberately. Deloitte found that more than one-third of managers feel unprepared for the people-management parts of their job. Coaching, feedback, and conflict management are teachable skills. The organizations that close this gap are the same ones reporting 79% manager engagement.
Start with one business unit. Measure manager hours, team engagement, and voluntary turnover before and after the changes. Use that evidence to justify the next rollout.
The bottom line
Manager burnout is a design problem, not a personal failing. The role has widened while support has stayed flat, and the 2026 data now show the consequences in engagement scores, efficiency losses, and turnover intent. Organizations that protect manager capacity will protect team performance. Those that keep adding initiatives without adjusting the job will keep watching the numbers fall.
Where to go from here
CEOs and senior leadership teams need a clear view of where manager capacity is breaking before burnout becomes turnover. Start with an assessment that measures workload, span of control, and the people skills managers need most, then build a targeted development plan for the managers who carry the heaviest load.
