Declaration of strike at Stellantis Mulhouse plant due to extreme heat

Mulhouse – June 23, 2026: The union Confédération Générale du Travail (CGT) has declared a strike at the Stellantis Mulhouse plant to highlight the extreme working conditions caused by high temperatures. In some work areas, temperatures have reached between 38 and 40 degrees Celsius, threatening the health of workers. Accordingly, the CGT is demanding that both the early and night shifts end their working hours earlier.

In recent days, the high temperatures at the Stellantis Mulhouse plant have caused great concern among workers. Union representatives warned that temperatures in some areas have reached 40 degrees Celsius, significantly worsening the working conditions. The CGT strongly insists that adjusting working hours is necessary to protect workers’ health.

Stellantis has previously invested in the Mulhouse production facility. In June 2026, an investment package of over 1 billion euros was announced, of which about 400 million euros is planned to be invested in the production of three new Peugeot models in Mulhouse. These investments highlight the importance of this manufacturing facility.

The CGT emphasizes that the current working conditions not only threaten the health of workers but could also affect production quality. The union demands that Stellantis take urgent measures to improve the working environment and ensure workers’ safety.

The announced strike is one of a series of actions the CGT has carried out in several sectors over the past few months to draw attention to poor working conditions and related issues. The union stresses the need to continuously monitor and adjust the working environment as necessary to protect workers’ health and safety.

The situation in Mulhouse reflects a larger problem occurring in many industrial facilities during heatwaves. High temperatures can lead not only to reduced productivity but also to health problems for workers. Therefore, it is important for companies like Stellantis to take proactive measures to prevent such situations and ensure employee safety.

The CGT has stated that the strike will continue until a satisfactory solution is reached. The union calls on Stellantis to adjust working hours and ensure that the working environment meets health standards. It emphasizes that the safety and well-being of workers must be the top priority.

The situation in Mulhouse remains tense, and it will be important to watch how Stellantis responds to the CGT’s demands. It is hoped that quick and effective solutions will be implemented to improve working conditions and prevent further strikes.
