As Britain prepares for potentially record-breaking temperatures reaching 40C, there is a growing debate on whether workers should be required to work in such scorching conditions. The intense heat can lead to exhaustion, dehydration, and reduced productivity, yet there are no set limits on maximum working temperatures for employees.

The Met Office has highlighted that the rising temperatures are a clear indication of the rapid changes in our climate. The Climate Change Committee has emphasized the need for the UK to adapt to the new climate reality and protect workers by implementing legislation on maximum temperatures.

Baroness Brown, chair of the CCC’s Adaptation Committee, emphasized the importance of addressing the challenges posed by climate change and criticized the lack of action from past governments. She stressed the need for measures to safeguard the British way of life from the impacts of climate change.

In response to these concerns, the government has committed to reviewing the committee’s recommendations. While no specific maximum temperature is proposed, the example of Spain, where indoor working temperatures are regulated, is cited as a reference point.

A recent report by the Autonomy Institute revealed that a significant portion of the UK workforce could be working in extreme heatwaves exceeding 35C by the end of the decade. It estimated that around six million workers, especially in sectors like construction and agriculture, are already exposed to dangerous levels of heat.

Recommendations include setting a maximum acceptable working temperature of 27C for employees, aligning with guidance from the Trades Union Congress. The TUC has advocated for a maximum indoor temperature of 30C and called for measures to lower temperatures above 24C.

Additionally, the Autonomy Institute proposed that workers should have the right to stop working during extreme heat, along with provisions for shelter and rest breaks. TUC general secretary Paul Nowak emphasized the importance of setting legal limits to ensure workplace safety, especially with the increasing frequency of extreme temperatures.

The Health and Safety Executive noted the complexity of regulating maximum working temperatures due to the diverse nature of workplaces. However, the need for ensuring safe working conditions in the face of rising temperatures is a pressing issue that requires attention from policymakers and employers.
