Heat-Related Productivity Loss in Germany Tops €6.3 Billion; Union Seeks Legal Compensation for Workers

When outdoor temperatures pass 27°C, efficiency begins to erode. At 30°C, every additional degree strips away three percent of worker output. On days exceeding 35°C, the cost to the German economy reaches roughly €948 million per day, according to data from Allianz Trade. The Wuppertal Institute has labeled this a serious warning sign.
New figures from the Prognos Institute attribute at least €6.3 billion in economic damage to the heatwave that struck Germany at the end of June 2026. Nearly all of that sum – 97 percent – stems from lost productivity. Manufacturing absorbed the heaviest blow, with €1.9 billion in losses. The healthcare sector followed at €662 million, retail at €580 million, and construction at €460 million.
The heatwave's impact on productivity is a stark reminder that workplace risks can have serious financial consequences. For UK employers, failing to document and manage these risks properly can also lead to hefty fines.

The German Trade Union Federation (DGB) is now calling for a statutory "heat pay-loss benefit" – a form of compensation for workers whose income suffers when heat forces a slowdown or shutdown. DGB chairwoman Yasmin Fahimi likened the proposal to the seasonal short-time work allowance already used in the construction industry. Her demand comes as a DGB survey of 4,000 employees reveals that more than one in three feel strongly impaired by heat on the job. Among those working under time pressure, the share jumps to 48 percent; without time pressure, it falls to 23 percent.
Fahimi also insists on better workplace protections: consistent shading, free drinking water, and relaxed dress codes. The construction union IG BAU has long pressed for financial safeguards during heat disruptions and backs the call. For outdoor laborers, IG BAU recommends the "WSS rule" – water, sunscreen, shade. Employers should offer a "drinks flat rate," providing three to five liters of water daily for heavy physical work, along with sun protection factor 50 and reapplication every two hours.
Some companies are already acting independently. A Basel-based firm cut working hours to six at full pay once temperatures exceed 30°C. Safety concerns drive such measures: the Swiss accident insurer Suva reports that the risk of workplace accidents rises seven percent above 30°C. In Lower Saxony, unions are urging employers to shift work schedules to the cooler morning and evening hours.
On the political front, Chancellor Friedrich Merz has signaled a draft bill on working-time reform for autumn 2026. The plan would switch from a daily to a weekly cap on maximum hours, giving firms more flexibility. The German Hotel and Restaurant Association (Dehoga) welcomes the move, while the DGB opposes any extension of the daily working limit.
Authorities are simultaneously stepping up enforcement. In South Tyrol, regional labor councilor Magdalena Amhof reported intensified construction-site inspections since the start of summer. Berlin has already recorded nine heat days this summer – in the 1950s, the city averaged fewer than five per year.
