General Motors will cut close to 1,300 jobs through Feb. 28 at its Warren Technical Center, according to filing with the state of Michigan.

The cuts are part of GM's plan to eliminate some 4,000 jobs across North America. It started making those cuts Monday, and employees say human resources has "walked out" hundreds of people in some of GM's regional offices.

But the 1,298 cuts at the Technical Center will be the most in any one location, some analysts say, mostly because that is where the most GM salaried employees work. Because of the ice storm Wednesday in Michigan, many GM salaried staff worked from home, putting a pause on pink slips issued Wednesday, said a GM employee who works in Warren and asked to not be identified our of concern about job security.

When the layoff process resumes, the state filing indicates it will continue through Feb. 28. The filing, under the Worker Adjustment and Retraining Notification (WARN) Act, is dated Feb. 4.

The filing states that as a result of GM's plans, "Our employees' compensation for wages and benefits will continue through and including April 9, 2019."

Late last year, GM transferred some 3,000 workers to Warren from Pontiac Powertrain to consolidate its work on electric vehicles. Also last year, Cadillac said it would relocate its headquarters from New York to offices near the Tech Center in Warren as it prepares to launch a new or redesigned vehicle every six months through 2021.

GM is cutting about 8,000 jobs, or 15 percent of its global workforce, to reposition the company to control costs and align its operations with a changing auto market. GM has said it believes in an all-electric future and plans to bring self-driving cars to market in the form of ride sharing this year.

As part of its efforts to trim costs and transform the company, GM said on Nov. 26 it would indefinitely idle five of its factories in North America, putting about 6,200 jobs at risk. Detroit-Hamtramck and Warren Transmission are two of those five plants.

GM has said the restructuring will save it up to $2.5 billion this year and up to $6 billion by 2020.

On Wednesday, GM reported 2018 pretax profits of $11.8 billion in 2018, down 8.3 percent from a year ago. GM's performance means its UAW workers will receive profit-sharing checks of up to $10,750.
