Dear Editor, April is Stress Awareness Month and I am writing to remind your readers about our new St John Ambulance mental awareness campaign, the Hi Vis Stress Vest, which was just launched. This initiative aims to address the critical issue of mental health in the construction industry, where nearly seven in 10 workers have suspected a colleague was suffering from serious depression but found it too difficult to talk about. What is more, our research revealed that almost a third of the UK construction workforce is currently struggling, overwhelmed, or suicidal, which was alarming to read.
