Regional panel models linked with national health survey further show:
• Short-term SL unrelated to changes in health indicators 👉 likely behavioural
• Long-term mental and musculoskeletal SL are significantly associated with work stress and pain-related limitations👉 likely health deterioration.

We further decompose the rise by diagnosis group and find:

▶️Musculoskeletal and mental disorders account for ~60% of the increase, with a clear age gradient.

▶️ Mental health is the largest contributor among workers <40, explaining 35–56%

▶️Musculoskeletal explains 35–43% for workers 50+

Short- and long-term spells behave very differently:

▶️Short-term sick leave: > 60% is explained by falling unemployment👉 likely behavioural responses due to stronger worker bargaining power

▶️Long-term sick leave: 90% unexplained 👉
likely health deterioration rather than strategic behaviour.

Which factors actually explain this surge?

▶️Oaxaca–Blinder decomposition shows that the most commonly discussed drivers explain only ~26% of the increase.

▶️~74% unexplained by workforce composition or observable characteristics.

▶️The large inflow of migrants actually reduces the expected rise.

We find a 36% increase in the share of working days lost to sick leave driven by:

• short spells (≤7 days): +38%
• Very long spells (17+ weeks): +39%

The increase is strikingly broad-based and parallel across SE groups.

This points to common forces rather than isolated, group-specific changes.
