General Motors Co. said Monday it will layoff 1,100 workers in May at its Lansing Delta Township assembly plant in Michigan as it shifts production of a vehicle to Tennessee.

The largest U.S. automaker last year added 800 jobs at its Spring Hill, Tennessee plant to build a new version of the GMC Acadia SUV. The Lansing plant will continue to build the Buick Enclave and Chevrolet Traverse after it retools for a month.

GM has announced some other U.S. factory cuts in recent months even as it said in January it would invest another $1 billion in U.S. factories.
