The cuts go all the way to the top, as GM plans to cut a quarter of its executive team in an effort to streamline operations and maintain profitability. "There are tens of thousands of feeder jobs that originate from this plant alone", Carrie said.
The plant in Lordstown, Ohio, which makes the Chevrolet Cruze compact vehicle also is on the list, and Barra said the Cruze would no longer be sold in the U.S. Production would stop March 1.
Barra said the automaker is running at about 70 percent capacity utilisation in North America, and the company will provide an update on how the latest moves will improve utilisation in January.
Most of the factories to be affected by GM's restructuring build cars that won't be sold in the US after next year.
Jerry Dias, head of the Unifor union that represents about 2,500 employees at the plants, said he does accept that the company has planned no autos for the factory beyond December, 2019.
"This is a warning and we all must be concerned about protecting jobs and keeping them in this country". The Cruze compact vehicle will be discontinued in the United States market in 2019.
"You will see us have new employees joining the company as others leave the company", Barra said.
As recently as 2012, passenger cars made up more than 50 percent of all USA new vehicle sales. We want to make sure we're well positioned, Ms. Barra told reporters. The U.S. plants are in places that have been economically devastated by job losses and pressure on wages for decades, which helped lead to the 2016 election of Donald Trump as U.S. president. Production began on November 7, 1953, and in the 1980s the plant employed roughly 23,000 people.More news: Salah denies Egypt coach exit claims: I will win trophies for Liverpool

Industry analysts are already plotting out possible targets for GM, including its sprawling Lordstown plant in northeastern Ohio.
Plants in Baltimore, Maryland, and Warren, Michigan that assemble powertrain components will have no products assigned to them after 2019 and thus are at risk of closure, the company said.
The decision is "devastating" for workers at the plant and auto suppliers, but Oshawa has adapted over the years and will survive this as well, DesRosiers added.
Todd Smith, Ontario's minister of economic development, did take a swipe at Ontario Liberals when he said GM's decision speaks to "15 years of mismanagement". The company offered buyouts to 18,000 white-collar workers in October, but hasn't said how many accepted. "Despite mounting debt and deficits, rising inflation and interest rates, billions in lost investment, and a crisis in Canada's energy sector, Trudeau insisted all was well".
GM said it would end production next year at three North American assembly plants and two smaller transmission factories, which combined employ more than 6,700 workers. That represents just 0.7 per cent of all employment in the province, but 71 per cent of all Canadian auto manufacturing jobs.
While GM declined comment on the announcement, the end of a product line doesn't necessarily result in the closure of a plant.
In October, almost 65% of new vehicles sold in America were trucks or SUVs.
"If GM Canada is indeed turning its back on 100 years of industry and community - abandoning workers and families in Oshawa - then this is a callous decision that must be fought", she said in a statement.
