But Rich Boyer, head of the UAW's Stellantis Dept., says in a letter sent to local union officers that more than 1,600 supplemental employees could be at risk of being laid off. In the letter, Boyer notes Stellantis and its principal U.S. subsidiary, Fiat Chrysler Automobiles, converted or promoted 2,857 of the company's 5,219 supplemental employees to full-time status when the new contract was ratified in November. The number of supplemental employees promoted to full-time status included more than 900 at the automaker's Jeep complex in Toledo, OH, according to Boyer. Stellantis also has told the UAW it expects to keep 500 supplemental employees in a pool to cover for absent workers at various assembly plants, Boyer says. However, Boyer's figures indicate anywhere from 1,600 to 1,800 of the supplemental employees could be laid off because they will lack the seniority to convert to full-time status as the new labor contract requires.
