General Motors Corp. says it will lay off about 2,000 more factory workers early next year as the U.S. auto sales slump continues to wreak havoc on domestic automakers.

Spokesman Chris Lee says the company will cut shifts at car factories in Lordstown, Ohio; Orion Township, Michigan.; and Oshawa, Ontario, in February due to slowing demand for their products.

Lee says the company plans to lay off 890 workers at the Lordstown, plant and 390 jobs on Feb. 2 at Orion Township. Another 700 workers will be laid off in Oshawa on Feb. 9.

Lordstown makes the Chevrolet Cobalt and Pontiac G5 small cars. The Orion plant makes the Chevrolet Malibu and Pontiac G6 sedans and Oshawa makes the Chevrolet Impala.
