Can highly engaged employees burn out?
Yes. thrive research (2026) shows employees in the Burning out group, with high engagement and low capacity, report 59 days a year when they could not work effectively, against 18 in the Thriving group. Their engagement differs by under 4 points; their capacity differs by almost 20. An engagement survey alone would report both groups as healthy.
- Burning out group: 59 days a year not working effectively.
- Thriving group: 18 days.
- Engagement differs by under 4 points.
- Capacity differs by almost 20 points.
- Engagement scores alone hide this group.
The finding in plain numbers.
The thrive matrix places people in four groups: Thriving, Burning out, Coasting and Depleted. The Burning out group looks almost the same as the Thriving group on engagement. On capacity it is almost 20 points lower, and it loses three times as many working days.
Other research points the same way.
University of Cambridge on engaged employees and burnout reported that many highly engaged employees also show signs of burnout. The thrive data shows how large the cost of that hidden group is in working time, and why engagement and burnout are not opposites.
How to spot the group.
Measure engagement and capacity separately and read the gap by team.
Look for teams above average on engagement and below on capacity.
Check overtime and evening work in those teams.
Talk to the team before morale drops.

What leaders can do.
Burning out teams need relief, not motivation. Reduce load, protect recovery and ask managers to remove low-value work. Read the playbook in committed but depleted.
What the numbers do and do not show.
These are associations between groups of employees, not proof of cause. Days of not working effectively are reported by employees themselves. The next studies test whether raising capacity changes outcomes and how scores line up with an employer's own absence and turnover records. Full methods are in the thrive at work white paper.

thrive at work measures engagement (purpose, leadership, connection, growth) and capacity (energy, recovery, focus, resilience) in one anonymous assessment: see how the assessment works.
Most engagement problems show up first as falling energy, recovery and focus. thrive at work is a workforce performance platform: an employee engagement platform that also measures capacity to perform, so you can see strain by team before it turns into absence or resignations.
