DETROIT (AP) – General Motors is adding 1,200 jobs at two Michigan factories to build midsize SUVs and two new luxury sedans. GM says the Lansing Delta Township plant will get a third shift and 800 more workers to build the Chevrolet Traverse and Buick Enclave SUVs, which have three rows of seats. The Lansing Grand River plant will get a second shift and 400 more workers to build two new Cadillac sedans, the CT4 and CT5. Spokesman Dan Flores says employees laid off at other GM factories would fill the new jobs first, then workers would be added. He says the company has not determined yet how many new people would be needed. Lansing Delta Township now employs about 2,500 salaried and blue-collar workers, while the Grand River plant has 1,400.
