Workers at the StarPlus Energy battery plant in Kokomo, Indiana—a joint venture between Stellantis and Samsung SDI—have officially secured union representation under the United Auto Workers (UAW). This comes after a majority of the plant's 420 employees signed authorization cards, prompting Stellantis to recognize the union through a card check process agreed to in its 2023 contract with the UAW. The successful organizing effort reflects the union’s broader push to ensure that new electric vehicle jobs offer fair pay and protections, contrasting with slower progress at other sites like Ford’s BlueOval SK in Kentucky. StarPlus is now among several battery plants across the U.S. where the UAW has gained a foothold amid the EV industry’s rapid expansion.
