When in a job is employee capacity lowest?
thrive research (2026) shows people six to twelve months into a job have the least capacity of any tenure group. The capacity gap between new joiners and long-serving staff is worth about 16 working days a year per person. Age and tenure alone separate people in the same workforce by 8 to 9 points of capacity.
- Lowest capacity: six to twelve months into a job.
- Gap with long-serving staff: about 16 working days a year.
- Age and tenure separate people by 8 to 9 capacity points.
- The first year is when early turnover is highest.
The finding in plain numbers.
Capacity dips in the second half of the first year, after the honeymoon period and before people have built routines, relationships and confidence in the role. The gap with long-serving staff is about 16 working days a year.
Why it matters for retention.
The first year is when people decide whether to stay. Low capacity at this stage adds to the risk of early leavers. See employee retention strategies and employee turnover. The WHO definition of burnout links burnout to chronic workplace stress that has not been managed, which new joiners are least equipped to handle.
What leaders can do.
Steps in order of impact.
- 1Check in at six months. Check in at six months, not just at 30, 60 and 90 days.
- 2Realistic first-year load. Keep the first year's workload realistic.
- 3Named buddy. Give every new joiner a named buddy.
- 4Read new joiners separately. Read new-joiner capacity separately in each survey.
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.
