As repeated heatwaves continue to affect the United Kingdom, London Mayor Sadiq Khan has backed calls from labor unions to establish a legal maximum temperature for workplaces. Unions argue that current health and safety regulations protect workers from cold conditions but fail to address the growing risks posed by extreme heat, with proposed limits of 30°C for most workplaces and 27°C for physically demanding jobs. Although Khan cannot implement the policy himself, he has voiced support for stronger protections and urged the national government to act. The debate reflects the increasing role of climate change in workplace health and safety discussions.
