General Motors' Lansing Grand River Assembly plant will lay off more than 800 workers when it cuts the plant's third shift in January.

According to the Lansing State Journal, the reason for the layoffs is a decline in demand for cars as customers continue to favor trucks and crossovers.  Lansing Grand River makes the Chevrolet Camaro, Cadillac ATS and Cadillac CTS.

Erin Davis, GM's Lansing spokeswoman said, "we need to continue to meet demand.  It's an unnerving situation.  It's a tough choice. But we're doing the right thing by not overproducing."

Across the company, GM is laying off 2,000 workers because of declining car sales.  GM is required to give employees 60 days notice prior to mass layoffs.
