The relentless heatwave gripping Europe has sparked a critical conversation about worker safety and the urgent need for new protections. As the continent swelters, trade unions are leading a charge for legislative change, highlighting the deadly impact of heat stress on employees. With estimates suggesting over 20,000 heat-related deaths across Europe this year alone, the issue is no longer just an environmental concern but a pressing occupational health and safety matter.
The Call for Action
Unions are advocating for enforceable thermal limits in workplaces, measured by the Wet Bulb Globe Temperature (WBGT) index, which assesses the body's ability to regulate its temperature. They're also pushing for mandatory heat risk assessments, heat breaks, outdoor shade, water access, cooling measures, and adjusted working hours. These demands are outlined in a draft directive, supported by three major union groups representing 15 million workers, and are gaining traction among sympathetic MEPs and officials.
A Legal Framework Under Scrutiny
Enrico Somaglia, General Secretary of the European Federation of Food, Agriculture and Tourism Trade Unions (Effat), argues that the current European legal framework is inadequate to address the risks posed by climate change. He emphasizes that the issue is not just about health and safety but also job stability. As the summer of 2026 intensifies, the political agenda is shifting to prioritize these concerns.
Proposed Solutions
The draft directive proposes maximum workplace WBGTs ranging from 30°C to 32.5°C, depending on the intensity of work. Beyond these limits, work would be suspended, and employers who fail to comply would face sanctions. This approach aims to provide a clear and enforceable standard for worker protection.
A Groundswell of Support
Effat is joined by the European Federation of Public Service Unions and the European Federation of Building and Woodworkers, reflecting a broader movement within the union community. In the UK, where an amber heat alert has been issued, the Trades Union Congress (TUC) is calling for a maximum working temperature of 24°C, with the right for workers to stop work at 30°C or 27°C for strenuous jobs. This demand is supported by the government's Climate Change Committee.
Practical Steps for Employers
Paul Nowak, TUC General Secretary, emphasizes the need for proactive measures. He suggests keeping indoor workplaces comfortable, with relaxed dress codes and flexible working hours to utilize the coolest parts of the day. For outdoor workers, regular breaks, ample fluids, sunscreen, and protective clothing are essential. These steps are not just about compliance but about creating a safe and productive work environment.
The Heat Strike Movement
The Heat Strike movement, born after the UK's hottest day in 2022, has gained momentum. Activists, supported by various unions and environmental groups, have set up cool stations and organized symbolic walkouts to raise awareness and show solidarity with workers in extreme heat. This grassroots effort reflects a growing public consciousness about the impacts of climate change on daily life and work.
The Bigger Picture
Global heating is accelerating, and Europe is warming at twice the rate of the global average. Research indicates that up to 130 million workers are now exposed to workplace heat stress, with over a quarter of a million injuries each year. Maria Ohisalo, a Finnish Green MEP, supports the union push and emphasizes the need for legally binding, harmonized rules to protect workers across Europe. While the European Commission has pledged to bring forward a Quality Jobs Act this year, it faces opposition from labor ministers in right-wing EU states who favor weaker recommendations.
Conclusion
The push for new worker protections in Europe is a critical step towards mitigating the impacts of climate change on occupational health and safety. As the heat continues to rise, the conversation around worker rights and well-being becomes increasingly urgent. It's a reminder that climate change is not just an environmental issue but a human one, with profound implications for our daily lives and livelihoods.
