A recent report by *Le Monde* highlights a lack of preparedness among French employers regarding extreme heat events. As over half of France was under red alert this Tuesday, employees and civil servants shared experiences of inadequate workplace adjustments for the heatwave. Some reported being required to wear identifiable work vests even in scorching temperatures, prioritizing visibility over comfort and health. The testimonies reveal a broader issue of insufficient anticipation and planning by companies to protect workers during increasingly frequent and intense heatwaves. This includes a failure to modify work schedules or provide appropriate equipment. The situation underscores growing concerns about worker safety in the face of climate change and the need for updated workplace regulations. The report suggests a disconnect between official guidance and practical implementation within French businesses.
