GM lays off 1,000 workers worldwide, including 500 in Michigan

General Motors has laid off about 1,000 of its global employees, including 560 working at sites in Warren and Milford, Michigan.

Affected workers were given notice of the layoffs on Friday.

“We need to optimize for speed and excellence. This includes operating with efficiency, ensuring we have the right team structure and focusing on our top priorities,” GM said in a statement.

Of the people let go, 507 of them worked at the Warren center, about 100 of them in engineering. And 60 employees, 44 hourly and 16 salaried, were let go as GM shuttered its durability, corrosion and teardown departments at the Milford facility. 

GM will also stop using a Yuma, Arizona, facility for testing vehicles in hot weather, leading to 33 more cuts, according to the Detroit Free Press.

The layoffs are just the latest cuts the company has made to its workforce this year. Another 1,000 in the GM software department were let go in August, while 1,700 jobs were terminated at a manufacturing plant in Kansas City, Kansas, in September.

The United Auto Workers union, which represented some of those laid off at both Michigan facilities, has not responded to a request for comment.
