Since then, the company has cut about 1,500 contract jobs and more than 2,250 workers have taken a voluntary buyout, the report said.
A source inside this company assured NBC News that while these layoffs were bad, they would not be as bad as "Black Friday", referring to the massive layoffs that occurred before GM filed for bankruptcy in 2010.
But the move enraged Trump, who repeatedly lambasted GM CEO Mary Barra over the decision.
The layoffs are part of a cost-cutting plan GM announced in November, which will slash 15 percent of its salaried and contract staff and shutter seven plants, including five in North America.
That said, the largest of the Detroit-based carmakers will, with the latest cuts, have eliminated more than 14,000 jobs in the USA and Canada since November.
"We've indicated that the involuntary reductions would happen in the first quarter", GM spokesman Pat Morrissey told the newspaper.
Michigan - Detroit/Hamtramck Assembly: Manufacturing plant for the Cadillac CT6, the Buick LaCrosse, the Chevrolet Volt, and the Chevrolet Impala.
In all, the automaker plans to eliminate six slow-selling passenger auto lines that include the Cadillac flagship, the CT6 sedan, as well as its first plug-in hybrid, the Chevy Volt.
US media reports said the company planned to lay off at least 4,000 salaried workers in North America starting February 4.
GM officials have stressed that their goal is to trim back the GM organization before it faces the next recession - with many analysts predicting that USA vehicle sales will begin at least a moderate decline this year after an unexpected upturn in 2018.
Unhappy with the announcement, President Donald Trump said at the time new auto tariffs were being "studied". GM said the actions - which were roundly criticized by U.S. and Canadian politicians - would save $6 billion in costs.
Many of GM's hourly workers in the United States and Canada have held protests and prayer vigils in a campaign to persuade the automaker to reverse its November 26 GM announcement to indefinitely idle five plants in North America. Eventually, the automaker hopes to transfer several thousand to other factories producing hot-selling SUVs, CUVs and pickups in order to help boost production.
GM is filing new required mass layoff notices with state agencies and disclosed the cuts to lawmakers.
