At the factories, 3,000 workers could lose jobs in Canada and another 3,600 in the U.S. GM, the largest automaker in the U.S., which sells the Chevrolet, Buick, Cadillac and GMC brands, said the moves will save $6 billion in cash by the end of next year, including $4.5 billion in recurring annual cost reductions and a $1.5 billion reduction in capital spending. Those cuts are in addition to $6.5 billion that the company has announced by the end of this year. GM doesn't foresee an economic downturn and is making the cuts "to get in front of it while the company is strong and while the economy is strong," CEO Mary Barra told reporters.
