The intense heatwave currently sweeping across Europe is forcing a re-evaluation of whether existing workplace safety protections are adequate for an increasingly warming climate. This atmospheric shift has prompted health experts and trade unions to demand that the European Union introduce binding regulations to shield employees from the dangers of extreme temperature exposure. Many regions across the continent have already documented abnormally high heat levels during the early summer season, resulting in the issuance of heat alerts in multiple member states.
Scientific evidence consistently indicates that climate change is fueling both the frequency and intensity of these heat events, which are rapidly evolving into a major occupational hazard. Trade unions now categorize the impacts of climate change as both a broader labor concern and a critical occupational safety and health issue. Andreas D. Flouris, a physiology professor at the University of Thessaly and a coauthor of a recent report, told EUobserver on Thursday, June 25, that all relevant stakeholders—including governments, employers, and workers—are in agreement that heat represents a systemic issue requiring immediate intervention. Notably, research highlights that at 32°C, worker productivity can drop by 40 percent.
The statistics regarding this crisis are stark. Since 2000, the European Union has seen a 42 percent increase in workplace fatalities linked to heat. Furthermore, the World Health Organisation recently released data showing that, within the last four years alone, extreme heat has been responsible for more than 200,000 deaths across the EU and its associated countries. The organization asserts that the overwhelming majority of these fatalities were entirely preventable.
The European Trade Union Institute (ETUI) is preparing to release a new report in the coming days, arguing that heat exposure must be classified as a distinct workplace risk that necessitates specific preventive measures instead of merely reactive, emergency responses after incidents occur. Marouane Laabbas-el-Guennouni, an ETUI researcher and report coauthor, emphasized that the goal is to protect workers in their daily lives by effectively translating scientific data into practical workplace safety standards that ensure continuity.
While trade unions favor the implementation of new EU-level rules to steer national legislation—thereby establishing union-wide obligations while respecting national labor policy competencies—existing frameworks remain insufficient. Current EU law mandates that employers assess workplace risks, yet unions argue that these requirements fail to adequately address extreme heat. Unlike physical hazards such as chemical exposure measured in parts-per-million or noise levels measured in decibels, there is currently no EU-wide maximum legal working temperature.
Ivan Ivanov, political secretary of the European Federation of Trade Unions in the Food, Agriculture, and Tourism (EFFAT), stated that it is the federation’s role to highlight these emergencies, insisting they must be treated as significant problems requiring resolution.
