Stellantis MiLus Factory Declares Strike Due to Extreme Heat

Mulhouse – June 23, 2026: The General Confederation of Labour (Confédération Générale du Travail, CGT) announced it will launch a strike at the Stellantis Mulhouse factory to draw attention to the extreme high-temperature working conditions. Temperatures in some workshops reach 38 to 40 degrees Celsius, endangering workers’ health. Therefore, the CGT demands an early end to the shifts for both the early and late teams.

Recently, the high temperatures in the workshops at the Stellantis Mulhouse factory have raised concerns among employees. A union representative warned that temperatures in some areas reach up to 40 degrees Celsius, severely impacting working conditions. Consequently, the CGT demands adjustments to working hours to protect workers’ health.

Stellantis has previously invested in the Mulhouse site. In June 2026, it announced an investment plan exceeding one billion euros, of which about 400 million euros are allocated to produce three new Peugeot models in Mulhouse. This investment highlights the plant’s importance to the automaker.

The CGT emphasizes that the current working conditions not only endanger workers’ health but may also affect production quality. The union calls on Stellantis to take urgent measures to improve the working environment and ensure employee safety.

The announced strike action is part of a series of measures undertaken by the CGT in recent months against poor working conditions and insufficient provisions. The union stresses that continuous monitoring and timely adjustments of working conditions are necessary to protect workers’ health and safety.

The situation in Mulhouse reflects a larger issue faced by many industrial facilities during heatwaves. High temperatures not only impact productivity but can also cause health problems among employees. Therefore, companies like Stellantis must take proactive steps to prevent such situations and ensure employee safety.

The CGT has announced it will continue the strike until a satisfactory resolution is reached. The union demands that Stellantis adjust working hours to ensure conditions meet health standards. The union emphasizes that employee safety and well-being must be the top priority.

The situation in Mulhouse remains tense, and it remains to be seen how Stellantis will respond to the CGT’s demands. It is hoped that a prompt and effective solution will be found to improve working conditions and prevent further strikes.
