UNIONS have launched a week of action to protect workers from soaring temperatures.

More than 1,000 trade union health & safety reps have signed up to join a nationwide inspection of workplaces organised by the TUC to ensure workers are supported during the heatwave.

Working in high temperatures poses serious risks including sunstroke, heat stress and skin cancer, and hot weather can also lead to dehydration, tiredness, muscle cramps, fainting and even loss of consciousness. 

The weekend's temperatures climbed above 32°C as Britain endured its third heatwave of the summer.

TUC general secretary Paul Nowak said: “Everyone should be safe at work. But working in a heatwave can be dangerous — especially when your employer wants you to carry on regardless. That’s why union reps are taking action this week to keep their workmates safe in the heat. 

“And it’s why we’re calling on the government to strengthen legal protections with a maximum working temperature.”

Britain doesn’t currently have such legal limits. The TUC says that employers should take steps to reduce temperatures if they get above 24°C and workers feel uncomfortable, and that work should stop altogether above a maximum temperature of 30°C or 27°C for those doing strenuous jobs.

The Health & Safety Executive is currently reviewing guidance on the matter.

This week, trade union representatives will meet employers to discuss proactive measures they can take. They include keeping workplace buildings cool, having sensible hours and shaded areas for outdoor workers, allowing flexible working to avoid the hottest parts of the day and relaxing dress codes.

The TUC is calling for upgrades to buildings and infrastructure to ensure they remain safe and functional during heatwaves.

Mr Nowak said: “Most of us know that climate action is needed to protect our way of life and we can be proud of the progress we are making. 

“With wind, solar and nuclear, Britain is building a foundation of cleaner, cheaper energy. We must now look at ways to speed up progress. This will protect British industry and the people working in it.”
