Employee Well-being Index
Also known as Wellbeing Score, Burnout Risk Index
An employee well-being index combines survey items on workload sustainability, energy, stress and work-life boundaries into a single measure of how well people are coping. Read alongside absenteeism and engagement, it is the earliest reliable indicator of burnout risk in a team.
Formula
Well-being Index = Percentage favourable across the well-being item set, reported by team and by functionTrack the proportion in the lowest response band separately. A stable average can conceal a growing group at genuine risk, and that group is the one requiring action.
Worked example
- Scenario
- A 60-person function: 68% favourable overall, but 14% answering unfavourably on every workload item.
- Calculation
- Headline 68% favourable; at-risk segment = 14% consistently unfavourable
- Result
- A reasonable-looking average with a meaningful at-risk group underneath it
What good looks like
Norms vary by sector, with healthcare, emergency services and client-deadline businesses running lower. The internal signal that matters is a trend decline, or any team where the consistently-unfavourable group exceeds roughly 10–15%.
Why employee well-being index matters
Burnout is expensive and slow to reverse. It shows up first as declining well-being scores, then as absenteeism, then as resignations — often three to nine months apart. Catching it at the first stage is the difference between a workload conversation and a replacement hire.
How to improve it
- 1Report the at-risk tail, not just the average.
- 2Cross-reference with actual workload data — overtime, on-call rotas, project load — rather than treating it purely as a perception issue.
- 3Look at whether well-being tracks with specific projects or seasons, which points to planning rather than culture.
- 4Pair with absenteeism and voluntary turnover for the same teams to validate it as a leading indicator in your organisation.
Common mistakes
- Responding with wellness benefits when the data points at workload. Yoga does not fix understaffing.
- Averaging away the at-risk group.
- Measuring well-being without any intention or capacity to change workload, which reduces future response rates.
Frequently asked questions
How is a well-being index different from an engagement score?
Engagement measures commitment and discretionary effort; well-being measures sustainability. The dangerous combination is high engagement with low well-being — highly committed people working at a pace they cannot sustain, who tend to leave suddenly rather than gradually.
Related metrics
Absenteeism rate is the percentage of scheduled working time lost to unplanned absence. It excludes booked holiday and approved leave, isolating the unscheduled absence that disrupts coverage and often signals burnout or disengagement before turnover does.
Employee Engagement ScoreAn employee engagement score is a composite index built from several survey items covering commitment, discretionary effort and intent to stay. Unlike eNPS it is designed to be diagnostic, so the sub-scores that make it up matter as much as the headline figure.
Voluntary Turnover RateVoluntary turnover rate is the percentage of employees who choose to leave — resignations and retirements — as a share of average headcount. Isolating it from involuntary exits is what turns a turnover number into a retention signal, because only voluntary departures reflect decisions your organisation could have influenced.
Manager Effectiveness ScoreManager effectiveness score is a composite of survey items rating a manager on the behaviours that most affect their team — clarity, feedback, support for development, fairness and recognition. It is reported at team level and is consistently among the strongest predictors of both engagement and voluntary turnover.
