In a significant escalation of the ongoing strikes by United Auto Workers (UAW) union, workers at Stellantis's largest assembly plant went on strike on Monday, affecting the production of the profitable RAM 1500 pickup trucks. This walkout adds to the more than month-long strike that has impacted the three major Detroit automakers. The UAW attributed this latest strike by the 6,800 workers at the Michigan plant to Stellantis presenting the "worst proposal" regarding wage increases, temporary worker pay, conversion to full-time status, and cost-of-living adjustments.
Currently, over 40,000 union members at Ford, General Motors, and Stellantis are participating in the strike, which began on September 15. This accounts for around 27% of the Detroit Three automakers' workforce, making it a highly unusual and impactful campaign of simultaneous strikes.
The UAW has put forth several demands, including a 40% wage hike (with an immediate 20% increase), improvements in benefits, and extending union agreements to cover electric vehicle (EV) battery plant workers. The strike at the Sterling Heights plant mirrors the recent walkout at Ford's highly profitable Kentucky Truck assembly plant.
The impact on Stellantis is expected to be significant. Wells Fargo analyst Colin Langan predicts that production losses at the truck plant alone will cost the automaker approximately $110 million in operating earnings per week. Accounting for the strikes across the three companies, the overall hit to Stellantis is estimated to be around $200 million per week.
The Sterling Heights plant contributed about 16% of Stellantis's North American production and mirrors the scale of the strike against Ford's Kentucky plant. As Tim Ghriskey, a senior investment strategist at Ingalls & Snyder, explains, the pickup truck production is at the core of these companies' output. The demands from the labor union pose a considerable challenge for the automakers, making it difficult for them to comply fully. If the automakers do give in to all the demands, it could lead to negative consequences for their stock values.
The UAW and the automakers are also negotiating future wages and unionization policies for planned electric vehicle battery plants, which are joint ventures between the automakers and their South Korean battery partners. However, these discussions are complex since the ventures are separate entities and not covered by the master UAW contracts under U.S. labor law.
United Auto Workers President Shawn Fain personally met with workers as they left the Sterling Heights plant, expressing support and distributing picket signs. Fain has been vocal about the need for improved offers from the automakers and warned of further strikes at truck and SUV factories if the companies do not meet the demands. He has insisted that the companies can afford more than what is currently on the table.
On the other hand, Stellantis Chairman Bill Ford has expressed concerns about the toll the strike is taking on the company and the U.S. economy. Five weeks into the strikes, the economic losses for the auto industry have already surpassed an estimated $9.3 billion, according to Anderson Economic Group LLC.
While the strike at Stellantis's pickup plant is a significant development, labor experts view it as a positive sign that a deal may be within reach. Arthur Wheaton, director of labor studies at Cornell University, stated that Stellantis has been the tougher automaker to negotiate with. The fact that the UAW did not announce strikes at GM and Ford suggests that both parties may be closer to reaching an agreement.
As negotiations progress, the automotive industry anxiously awaits a resolution to the strikes, which have already had a substantial impact on production and economic stability.
