Burnout
A state that follows long overload at work: exhausted, detached, and less effective.
Burnout is a state that results from chronic workplace stress that has not been successfully managed. The World Health Organization describes it in ICD-11 as an occupational phenomenon with three features: exhaustion, growing mental distance from one's job, and reduced professional efficacy. Burnout builds up over months and shows early warning signs.

A state of exhaustion that builds up gradually from sustained overload at work.
Not a standalone medical diagnosis, and not the ordinary tiredness after a hard week.
Because the early signals are quiet, and high performers tend to read them as commitment.
Origin and research
Psychologist Herbert Freudenberger described burnout in 1974 among staff in social care settings. Christina Maslach made the concept measurable: her model separates exhaustion, cynicism as inner distance, and a sense of declining efficacy. In their 2016 review, Maslach and Michael Leiter show that burnout grows mainly out of the fit between person and workplace, for example workload, lack of control, or lack of recognition.
In ICD-11, the WHO defines burnout as an occupational phenomenon and explicitly does not classify it as a medical condition. Where exactly burnout ends and depression begins is still debated in research.
For high performers
Burnout announces itself long before your energy runs out. The typical early sign is growing distance: the team starts to irritate you, and wins feel like items checked off. High performers miss this phase easily because it stays invisible from the outside.
So watch your inner distance from work while your results still hold up. This is the phase with the most room to act: recovery you treat as seriously as any meeting, and an honest look at workload and control. If exhaustion and distance persist for weeks, have a doctor look at it.
Distinctions
vs. Mental fatigue
Mental fatigue follows a demanding day and clears with rest. Burnout builds up over months and persists after days off.
vs. Sustained pressure
Sustained pressure is the load. Burnout is one state it can lead to when recovery is missing for a long time.
vs. Depression
Depression is an illness that affects every area of life. Burnout refers to work. Telling them apart in an individual case is a job for a doctor.
Frequently asked questions
What are the signs of burnout?
Three signals that last for weeks: exhaustion that days off do not resolve, growing mental distance from your job, and the sense of achieving less despite the effort. Single bad weeks are part of working life. What matters is how long it lasts.
Is burnout a medical condition?
The WHO lists burnout in ICD-11 as an occupational phenomenon and explicitly does not classify it as a medical condition. The symptoms can still be serious. If you notice them over a longer period, have them checked by a doctor.
How can I prevent burnout?
By planning recovery as firmly as appointments and by ending lasting strains such as unclear roles or conflicts that never get resolved. Prevention works best while you still have energy. A regular look at workload and control shows early where things start to tip.
