The United Auto Workers (UAW) is threatening strikes against Ford and Stellantis due to unresolved local contracts and delays in reopening the Belvidere assembly plant, which had been promised to workers as part of a collective bargaining agreement. UAW President Shawn Fain announced a strike deadline for Ford's tool and die plant while also preparing for strike authorization votes against Stellantis, which is accused of failing to adhere to commitments made during last year's negotiations. Stellantis's delay in reopening the Belvidere plant, now scheduled for 2028 instead of 2027, is seen as a violation of the contract, prompting the UAW to consider strike action. The union seeks to pressure Stellantis to honor its investment commitments and timelines, which involve significant local economic implications. Meanwhile, Ford faces potential disruptions in vehicle assembly if strikes occur at its supporting facilities. The UAW's actions reflect ongoing tensions in the automotive industry as labor negotiations continue to unfold.
