Heat Waves, Presenteeism, and Unpaid Overtime: Three Crises Reshaping Germany’s Workplace Health Debate
07.06.2026 - 02:12:30 | boerse-global.de
Across the German-speaking world, a trio of workplace health challenges is intensifying: climate-driven sick leave, costly presenteeism, and systemic unpaid overtime. New data and court rulings are forcing employers and policymakers to confront gaps between legal frameworks and daily reality.
Heat makes workers sick – and costs mount.
Researchers at the Potsdam Institute for Climate Impact Research analyzed records from 9.7 million insured individuals. On days above 30°C, sick leave filings jump 3.5 percent. Prolonged heat waves amplify the effect significantly. The economic damage from a single three-day hot spell: roughly €32 million. Logistics, construction, and agriculture bear the brunt. In response, the Federal Institute for Occupational Safety and Health released updated guidelines calling for flexible hours and hydration protocols.
Presenteeism, not absenteeism, is the bigger drag on Swiss business.
The Swiss Trade Union Federation reports that illness-related absences now exceed pre-crisis levels by 80 million hours. The probability of permanent disability has risen 10 percent since 2020. But the surprise cost driver is presenteeism – showing up sick. Estimated annual price tag: CHF 33.7 billion. By contrast, absenteeism (staying home) accounts for CHF 18.6 billion. Switzerland also trails badly in risk prevention: only 46 percent of companies perform mandatory risk assessments, versus the EU average of 77 percent.

Berlin teachers log millions of unpaid extra hours.
The Education and Science Union is preparing lawsuits against the Berlin Senate, demanding a legally watertight system for recording teachers' working time. The trigger: a University of Göttingen study from June 2025. It found Berlin teachers perform more than two million hours of unpaid overtime annually. 64 percent work beyond their contractual obligation; 30 percent regularly exceed the 48-hour weekly limit. Teaching itself consumes just 31 percent of their actual working hours. To close the gap, the city would need at least 1,300 extra full-time positions. A staff council in Tempelhof-Schöneberg has already called in the conciliation board.
Legal clarifications on vacation and minus hours.
The Thuringia Regional Labour Court ruled in March 2026 that company policies limiting consecutive vacation to two weeks are unlawful. Leave must generally be granted in one continuous block unless compelling operational reasons prevent it. Meanwhile, in Upper Austria, the Chamber of Labour secured back pay for a delivery-service employee whose employer offset negative hours against her holiday entitlement after an improper dismissal. The judges made plain: negative hours arising from low demand are an entrepreneurial risk and cannot be unilaterally charged to leave.
World Cup 2026: hospitality sector demands fair scheduling.
Ahead of the June 2026 football World Cup, the Food, Beverage and Catering Union in the Ruhr region is calling for early, fair rosters for the roughly 8,260 workers in Recklinghausen district. Collective bargaining, beginning mid-June, addresses not only wage increases but also adherence to rest periods. Industry experts stress that clear rules on TV viewing or live-score checking during events are needed – but smooth operations must always come first.
