It is reported that Angela Rayner has called for people to have the right to stop working during heatwaves. It was, to be fair, during her time in opposition, and her old tweet (from 2022) was, and is, in the public domain. So there’s no secret socialist plot.
On a newspaper story headlined “Unions call for maximum UK workplace temperature as heatwave descends”, she commented: “We need urgent guidance for safe indoor working temperatures and the government must ensure employers allow staff to work flexibly in this heat. Where is their plan to keep people safe?”
