Burnout

What burnout actually is

The World Health Organization folded burnout into the 11th revision of the International Classification of Diseases in 2019, and the classification is narrower than the word’s everyday use. WHO’s own wording: burnout “is included in the ICD-11 as an occupational phenomenon. It is not classified as a medical condition.” Three dimensions have to be present together: energy depletion or exhaustion, increased mental distance from the job or feelings of cynicism about it, and reduced professional efficacy. A hard sprint that leaves someone tired for a few days produces the first dimension. Burnout, by WHO’s definition, needs all three.

General workplace strain isn’t rare, even if the specific WHO combination is a narrower slice of it. EU-OSHA’s OSH Pulse 2025 survey found 29% of workers across the EU report stress, depression, or anxiety caused or made worse by their job — the broader pool the WHO-defined syndrome draws from, not a burnout prevalence figure itself. That’s still roughly three in ten people in the pool most European SMBs already employ or are hiring from.

Where the line sits

Work-life balance and burnout get used almost interchangeably in job postings, and the difference matters more than the overlap. Work-life balance is the broader hiring-policy question: how work and personal time are meant to divide across a whole team, stated as policy. Burnout is the specific three-symptom outcome above, in one person, that shows up when the policy isn’t followed in practice or wasn’t enough to begin with. A company can publish a generous work-life balance policy and still have someone on the team meeting all three of WHO’s criteria, because the gap between the policy and the actual week is exactly where burnout grows.

A sabbatical sits on the other side of it: something a company can offer once burnout, or the risk of it, is already recognised. It’s a genuinely useful response for the person already affected. What it doesn’t do is touch whatever produced the condition in the first place. Someone typically returns from a sabbatical to the same headcount gap and the same workload that caused the first episode.

This entry also covers overworking, on purpose. WHO’s three dimensions describe the outcome; overworking (hours or load sustained past what a role can absorb) is usually the mechanism that gets there. Splitting the cause from the WHO-defined result into two separate glossary entries would mean writing the same three symptoms twice, under two headwords, instead of once under the term people actually search for both.

How to decide what to do about it

The default employer response is a wellness perk: a meditation-app subscription, an extra floating day off, a resilience webinar. None of the three touch what WHO’s definition actually names. None of them reduce the workload behind the exhaustion, restore the autonomy behind the cynicism, or say anything about whether work is distributed fairly enough to fix the drop in how effective someone feels. Join sells hiring software, and the honest structural fix — usually “this team needs another hire” — happens to be the answer that sells more of it. Flag that upfront rather than pretend the incentive isn’t there. It still doesn’t change the recommendation: fix the workload, the decision-making room, and the fairness of the split first. A perk belongs on top of that work, never in place of it.
