Unions are pressing for workers being given legal protection against soaring temperatures.
With temperatures possibly hitting a record 40C or more in the next couple of days, they said there should be a maximum temperature for work. The GMB suggested it should be set at 25C, saying employers should allow flexible working and travel arrangements, give staff extra breaks and allow them to wear cooler clothes.
Lynsey Mann, the GMB’s health and safety officer, said: “This hot weather is great for being on a sun lounger, but if you’re trying to work through it’s no joke. Bosses need to do everything possible to keep workplaces cool and, more importantly, safe.
