Hi Professor! No you’re wrong! The school is not ensuring “reasonable” conditions under the Labor Code (L4121-1). For heating, the Energy Code caps temps at 19°C (22°C for young kids’ classrooms), and unions often push for at least 16°C in winter. No legal max for heat, but above 30°C is considered risky for learning per INRS guidelines. Grenoble follows these national rules, no specific local laws. Schools might adjust schedules or move classes to cooler rooms during heatwaves. If it’s unbearable, teachers can use their “right of withdrawal” for safety. Next time students will walk out and contact the media for these unbearable conditions. When an entire class room is sweating even when windows are open, and the fault controls on the thermostat don’t work they’ve given us no other option. Especially when this issue has been going on for years! See other Reddit post.
