Burnout
Definition
A syndrome conceptualised in the WHO's ICD-11 as resulting from "chronic workplace stress that has not been successfully managed," characterised by three dimensions: feelings of energy depletion or exhaustion; increased mental distance from one's job, or feelings of negativism or cynicism related to it; and reduced professional efficacy. WHO classifies burnout as an occupational phenomenon, not a medical condition, and limits the term to the occupational context.

Overview
What it means
The classification is consequential: by naming burnout an occupational phenomenon, WHO locates responsibility in work organisation and management — workload, control, fairness, reward — rather than individual frailty.
For sustainability practice, burnout sits in the "S" of ESG: it is a human-capital risk affecting retention, safety and performance, and its prevalence is a diagnostic of whether "people sustainability" claims match workplace reality. Measurement typically uses validated instruments such as the Maslach Burnout Inventory.
How it is used
Employers address burnout through workload redesign, psychosocial risk management and wellbeing programmes; disclosure frameworks (ESRS S1, GRI 403) touch psychosocial hazards; investors treat workforce wellbeing indicators as proxies for human-capital management quality.
Why it matters
Burnout is the stress test of social sustainability claims: an organisation cannot credibly claim to sustain value while systematically depleting the people who create it.
