European unions demand right to halt work on days over 30°C

Europe’s largest trade unions have called for a new legal right that would allow workers to cancel or postpone work on days when temperatures rise above 30 °C. The demand, framed as a response to the growing frequency of heatwaves across the continent, seeks to protect employees from the health risks and productivity losses associated with extreme heat.

The unions, representing millions of workers in EU member states, argue that current labor regulations do not adequately safeguard employees from heat stress. They propose amendments to the EU Working Time Directive and national labor laws that would obligate employers to provide alternative duties or paid leave when temperatures exceed 30 °C. Citing studies linking high temperatures to heat exhaustion, cardiovascular incidents and increased workplace accidents, the unions urge the European Commission and national governments to adopt binding regulation that ensures workers can refuse or reschedule work under such conditions.

The call comes amid the EU’s commitment to the Paris Agreement and the European Green Deal, which predict a rise in the number and severity of heatwaves. While industry groups have raised concerns about potential operational disruptions, the unions emphasize that protecting worker health is essential for long‑term productivity. The proposal is currently under discussion in the European Parliament, with a vote expected later this year.
