The ongoing negotiations between Stellantis and the UAW could have significant implications for the company's labor costs and operations. If the UAW accepts the offer, it could lead to increased labor costs, which could negatively impact the company's profitability. Conversely, if the UAW rejects the offer, it could lead to labor disputes and disruptions in the company's operations. Therefore, the outcome of these negotiations could have a significant impact on Stellantis' stock.
