Most employees score lower on capacity than engagement, new research says

A new study from thrive at work finds 76% of employees score lower on capacity than on engagement, with the weakest quarter reporting 85 days a year of not working effectively versus 14 days for the strongest quarter. The findings suggest employers may be missing a major driver of performance if they rely on engagement alone.

Why it matters: - Capacity, not just engagement, helps explain whether employees can sustain performance over a full working year. - The research links lower capacity to more lost working time, weaker on-time delivery and lower employee loyalty. - The findings suggest engagement surveys alone can miss a major constraint on workforce performance.

What happened: - New research from thrive at work found that 76% of employees score lower on capacity than on engagement. - The quarter of employees with the lowest capacity reported 85 days a year of not working effectively because of exhaustion or stress. - The quarter with the highest capacity reported 14 such days a year. - The research was shared from San Francisco on Nov. 2, 2026.

The details: - Capacity measures energy, recovery, focus and resilience. - Engagement measures whether employees want to perform and whether work enables performance through factors such as leadership, growth and connection. - The average employee reported 48.5 days a year of not working effectively because of exhaustion or stress. - That equals nearly 10 working weeks, or about 22% of a 220-day working year. - The gap between the lowest-capacity quarter and the highest-capacity quarter is 71 days, or about a third of a working year. - Under more conservative conversions, the gap ranges from 52 to 65 days. - A 10-point increase in capacity is associated with about 19 fewer days a year of not working effectively, with engagement held equal. - Employees in the highest-capacity quarter said they completed 86% of priority tasks on time. - Employees in the lowest-capacity quarter said they completed 56% of priority tasks on time. - In the top quarter of the thrive index, 70% of employees would recommend their employer and 9% would not. - In the bottom quarter, 16% would recommend their employer and 57% would not. - Capacity ranked below engagement in all 90 demographic segments examined and in all 18 industries. - The two measures overlap by only about one-fifth, meaning each captures different information. - Engagement has the stronger link to whether employees would recommend their employer. - Capacity has the stronger link to lost working time. - With engagement held equal, each capacity point is associated with about 1.9 fewer days a year of not working effectively, about three times the effect of an engagement point. - The company positions capacity as a workforce performance measure that should be read alongside engagement.

Between the lines: - The research challenges a common assumption that engagement alone is enough to explain employee performance. - The gap between wanting to do the work and having the energy to do it appears to be large enough to affect output, loyalty and retention risk. - That makes capacity a practical metric for managers who want to spot performance constraints before they show up in missed deadlines or burnout.

What's next: - thrive at work says organizations use its platform to measure capacity and engagement, identify performance constraints and build action plans. - The company points readers to the Scientific Foundations White Paper for more detail. - The research program covers 7,031 employees and 216,301 responses across Europe and North America. - The study compares groups at one point in time, and the days-not-working-effectively measure comes from employee self-reports. - A 12-month study found survey answers tracked resting heart rate and heart rate variability, and changes in capacity moved with changes in heart rate variability. - thrive at work says its research focuses on energy, recovery, focus and resilience. - The company says it does not collect biometric data.
