The United Auto Workers (UAW) is threatening a national strike against Stellantis due to the company's alleged failure to honor its commitments to reopen the Belvidere, Illinois plant and make other promised investments. UAW President Shawn Fain has publicly accused Stellantis of violating the union contract by delaying the launch of key projects agreed upon during last year's contract negotiations. Stellantis maintains that it stands by its commitments but argues the current market conditions necessitate modifications to their investment plans. The union, representing tens of thousands of workers, asserts that Stellantis' actions jeopardize job security and future opportunities, prompting several local branches to prepare grievances. This dispute has also gained political attention, influencing rhetoric at the Democratic National Convention. If unresolved, the conflict could result in a significant strike impacting Stellantis’ operations nationwide.
