A German Court’s Drowsy-Driving Verdict Shines a Light on Employer Heat Duties

On April 17, the Landgericht Osnabrück handed down a ruling that jolted German employers: a driver who kept going despite fatigue and caused a microsleep crash could not escape a provisional license suspension. The court made clear that professional pressure does not excuse recklessness—and that at the first signs of heat stress, such as dizziness or headaches, workers must stop immediately and tell their employer.
The verdict arrives as much of Germany broils under record temperatures exceeding 41°C, and as a broader debate about heat protection in the workplace sharpens. Under existing German law, the Fürsorgepflicht (duty of care) already forces companies to act well before the mercury hits extreme levels.
From 26°C to 35°C: The Thresholds That Matter
The legal framework is precise. As soon as indoor temperatures reach 26°C, employee performance measurably drops. At 30°C, employers must respond: provide drinking water, implement ventilation plans, relax dress codes. The hard ceiling is 35°C. Without technical or organisational safeguards, that temperature renders a workplace unsuitable.
Keeping your workplace compliant with duty-of-care obligations—especially during heatwaves—requires properly documented risk assessments.

Austria is even more ambitious. Starting in 2026, its Hitzeschutzverordnung will kick in at a felt temperature of 30°C. Construction workers there will be able to down tools at 32.5°C and still receive 60% of their wages as compensation.
Unions Push for Paid Cooling Breaks Across the EU
On June 30, the European Trade Union Confederation (EGB) issued an urgent call: paid cooling breaks for every employee in the European Union, modelled on the rules used at football World Cups. Their reasoning is stark—above 30°C, accident risk spikes dramatically. The EGB wants the measure embedded in the planned Quality Jobs Act.
Meanwhile, the SPD parliamentary group in North Rhine-Westphalia is demanding a state programme to install air conditioning in schools, nurseries and nursing homes. Municipalities, they argue, cannot shoulder those investments alone.
Infrastructure Strains and Heat Deaths Mount
The scale of the problem is visible in building data. Only 4.3% of new residential buildings in 2025 included cooling systems, up from 1.9% in 2015. Offices fare better at 37.8%, but nurseries and nursing homes—where vulnerable people spend their days—lag at just 14.5%.

Outdoors, the consequences are concrete. On motorways in Rhineland-Palatinate and Baden-Württemberg, heat caused “blow-ups” as concrete slabs buckled. In Frankfurt, daily emergency call-outs surpassed 500. The World Health Organization warns that Europe is warming at twice the global average. The death toll already this summer is grim: France recorded over 1,000 heat-related fatalities since June 24, and Spain counted 892 extra deaths in June alone.
Travel, Outdoor Work, and the Drowsy-Pilot Problem
Heat also complicates business travel. Journey times by train or plane must be logged, and for field-service staff, the trip from home to the first customer already counts as working time. The Osnabrück ruling adds a layer of worker responsibility: when heat stress hits, pull over, rest, and notify the boss. Otherwise, the legal consequences—and the human ones—can be severe.
