Burnout

What is burnout?

The World Health Organization's International Classification of Diseases (ICD-11) describes burnout as an occupational phenomenon – not a medical condition – resulting from chronic workplace stress that has not been successfully managed. The WHO describes three dimensions:

1. Exhaustion – feeling drained of energy
2. Mental distance from one's job, or feelings of negativity or cynicism about it
3. Reduced professional efficacy – feeling less effective at work

Because the WHO definition relates specifically to work, burnout is different from general stress or from conditions such as depression, although symptoms can overlap. Anyone with persistent low mood, sleep problems or physical symptoms should talk to a doctor or mental health professional.

Common workplace causes

• Workloads that are consistently too high
• Little control over how or when work is done
• Unclear roles or conflicting expectations
• Lack of recognition or fairness
• Poor relationships with managers or colleagues
• Always-on communication and few real breaks

Signs managers may notice

• Someone who was engaged becoming withdrawn or cynical
• More mistakes, missed deadlines or irritability
• Frequent short absences, or working very long hours without results
• Comments such as "I can't switch off" or "nothing I do matters"

These are prompts for a supportive conversation, not for diagnosis.

Why it matters for employers

Since burnout is rooted in work, employers can do a lot to reduce it. Individual support, such as counselling, helps, but lasting change usually requires fixing the work itself: realistic workloads, clear priorities, fair recognition and managers who check in. A culture of psychological safety makes it easier for people to raise concerns early.

Example

A product team has shipped back-to-back releases for months. Several engineers report exhaustion in a pulse survey. The manager pauses non-essential work, sets "no-meeting" focus blocks, rotates on-call duty more fairly, and reminds the team about the employee assistance program. The team agrees to review workload every sprint.

Key takeaways

• The WHO describes burnout as an occupational phenomenon caused by unmanaged chronic work stress.
• It involves exhaustion, mental distance from work and reduced effectiveness.
• Prevention depends on work design and management, not only individual resilience.
