General Motors is making shift and staffing changes in the new year. The automaker is adding a second shift early this year at its Hamtramck Assembly plant, hiring more than 1,200 workers to meet demand for the five cars produced at the plant: Chevy Volt, Impala, Malibu, Cadillac EIR, and the upcoming Cadillac CT6. The Orion Assembly Plant, however, is another story: One of two shifts is being cut because of sluggish sales of the Chevy Sonic and Buick Verano. Some 500 workers from the Orion plant will be shifted to the Hamtramck plant.
