Heat Wave Fallout: Swiss Push for National Work Stop, Austria Enforces 491 Violations, Germany Faces €112 Billion Bill

The push for a unified heat-protection standard at construction sites has gained new urgency in Switzerland, as the Aargau Building Contractors' Association demands clear, nationally binding rules for shutting down work during extreme temperatures. Switzerland currently lacks enforceable criteria, though a political proposal won approval from the National Council in late 2024; the Council of States has yet to vote. The union Unia goes further, calling for an automatic work interruption on all building sites once the mercury hits 33 degrees Celsius. Recent heat waves in June drove peaks of 37 degrees, triggering level-3 and level-4 warnings across large parts of the country.
Germany, meanwhile, faces a staggering economic toll. Allianz Trade calculations project that heat waves could cost the German economy roughly €112 billion by 2030. Allianz economist Katharina Utermöhl warns the country is insufficiently prepared. Sickness absence data shows that on days above 30 degrees, sick-leave rates rise by an average of 3.5 percent; during prolonged heat waves the increase reaches up to 6 percent.
German employers have a clear legal duty to protect workers. From a room temperature of 26 degrees, protective measures must be assessed; above 30 degrees they must be implemented. At over 35 degrees, the workspace is deemed unsuitable for labor. Yet there is no statutory right to “heat-free” time off. Some municipalities have taken creative approaches: Freiburg lets waste-collection staff start shifts at 5:30 a.m. when temperatures exceed 25 degrees; in Lindau, a construction site was allowed to begin work at 6 a.m. to dodge the midday heat. The German Trade Union Confederation (DGB) rejects blanket siesta models, warning that a coalition of the Union and SPD could erode the eight-hour workday.
As legal duties to assess and manage heat risks expand across Europe, having the right documentation in place is essential — whether you're preparing for extreme temperatures or any other workplace hazard.

Across the border, Austria's new Heat Protection Ordinance — in force since January 2026 — has produced its first enforcement numbers. The Social Ministry conducted over 1,300 advisory sessions and more than 700 inspections. In six months, authorities logged 491 violations, the majority involving missing hazard evaluations. The ministry says it prioritizes advice before penalties. Labour Minister Schumann calls the regulation a “milestone for the protection of female employees.” The rules kick in once a heat warning of level 2 is issued — meaning temperatures between 30 and 34 degrees. Employers must then provide drinking water, shaded areas, or adjusted work schedules.
The Austrian Trade Union Federation (ÖGB) points to specific risks: concentration begins to drop at 30 degrees, and accident risk rises sharply at 32.5 degrees. In the German city of Fürth, construction workers reported extreme conditions in mid-June — over 45 degrees in direct sunlight, while the compulsory hard-hat rule remained rigidly enforced.
Heat deaths are a growing concern. Swiss National Councillor Patrick Hässig has urged wider use of air conditioning to protect vulnerable people. Data from the Federal Office of Public Health (BAG) shows that during August 2024, up to 20 heat-related deaths occurred per day, mostly among people over 75. A Canadian study underscores the risk: residents of nursing homes without air conditioning face roughly 8 percent higher mortality probability. A 2025 Barmer survey found that 64 percent of people in northern Germany worry about increasing heat waves, and 87 percent favor shorter working hours when workers are exposed to direct sunlight.
