Ford Motor Co (F.N) on Wednesday will start building its medium-duty F-650 and F-750 commercial trucks at a Cleveland-area plant, moving production out of Mexico for the first time. The shift to the 41-year-old plant in Avon Park, Ohio means that about 1,000 workers represented by the United Auto Workers union will keep their jobs, Jimmy Settles, UAW vice president, said in a statement issued by the company. There are about 1,400 workers at the Avon Park complex.
