Heat Strike week of action
14-20 July 2025
As the UK experiences multiple heatwaves, we all know that there's a big difference between high temperatures sitting in the shade on holiday and the same temperatures in workplaces which aren't designed to cope. There is still no maximum working temperature in the UK, just a minimum working temperature
Heat Strike is a campaign pushing for protections for workers during extreme heat. The campaign is calling for things like a maximum working temperature, heatwave furlough schemes, and proper climate mitigation plans. You can sign up for updates.
One of the key actions is encouraging union members to do lunchtime or after-work banner moments – standing outside your workplace with signs like 'Heat Strike' or 'Too Hot to Work' to highlight how unsafe it can be to work in these conditions. They can be downloaded here - or homemade is fine. Another idea is to take thermometers into work for a visual record of the temperature.
