The union had reportedly been negotiating with all three automakers simultaneously, in a break from previous rounds of contract talks, for significantly higher pay and new benefits.
Particularly, the UAW called for protections for workers with traditional auto jobs as companies increasingly invest in EV production.
In response, GM said in a statement issued Friday that it's ready to return to negotiations and get people to work as quickly as possible, "for the benefit of our team members, customers, suppliers and communities across the United States."
Analysts warned that the strike, though limited for the time being, may develop into a prolonged one and a menace to the U.S. economy, as it could cut production by thousands, push up vehicle prices and aggravate supply chain disruptions.
