Unions demand European law to limit extreme heat at work

Published on June 26, 2026 | Translated from Spanish

The European Trade Union Confederation has requested the European Commission to establish regulations setting a maximum working temperature, with paid breaks, water, and toilets. The measure responds to the increase in heatwaves affecting sectors such as construction and agriculture, where the risks of heatstroke and cardiovascular diseases skyrocket. It seeks mandatory protection for employees in the face of an increasingly frequent climate phenomenon.

The implementation of this regulation would require portable temperature and humidity sensors, as well as early warning systems connected to wearables. On construction sites and fields, drones with thermal cameras could monitor risk areas. Automated awnings, passive cooling clothing, and apps that calculate breaks based on the heat index are also being considered. All of this integrated into labor management platforms to ensure compliance with limits without relying solely on human supervision.

The boss will say: heat doesn't exist, it's a lack of attitude 😅

Because of course, nothing like an executive with air conditioning in their office to assure that sweat is a matter of willpower. While bricklayers are melting, the HR person will propose thermal resilience sessions or yoga under the sun. At least with the law, they will have the right to a glass of water without asking permission, even if it's at 45 degrees. But of course, they better not dare complain about paid breaks: otherwise, they say employees lack commitment.
