Qu'est-ce que Burnout ?
Definition
Burnout is a state of chronic occupational exhaustion resulting from prolonged exposure to excessive work demands without adequate recovery or resources. The WHO added burnout to its International Classification of Diseases (ICD-11) as an occupational phenomenon in 2019. It is characterised by three dimensions: emotional exhaustion (feeling depleted), depersonalisation/cynicism (detachment from work and colleagues), and reduced sense of professional efficacy.
In practice
In Belgium, burnout is recognised as a professional illness under certain conditions, entitling affected workers to income replacement (approximately 60% of salary, capped) through INAMI/RIZIV. The Belgian psychosocial risks framework (Royal Decree of 10 April 2014) requires employers to assess and manage workplace psychological risks. Risk factors include chronic overload, lack of autonomy, insufficient recognition, poor social support, value conflicts, and lack of fairness. Recovery from burnout typically takes 6–24 months of progressive return-to-work (mi-temps médical). Prevention is far more cost-effective than cure — managers play a critical role through workload monitoring, fostering psychological safety, and promoting recovery practices. Belgium has among the highest rates of long-term incapacity due to mental health in Europe, with burnout as a primary driver.
Key takeaway
Burnout is an organisational failure before it is an individual one — sustained high absence rates are a leading indicator that requires management and structural response, not just individual support.
