The United Auto Workers said its roughly 49,000 members who work at General Motors plants across the country will strike beginning at 11:59 p.m. Sunday evening.
A four-year contract between GM and the union expired Saturday and the two sides failed to reach a new agreement as talks broke down. GM said Sunday the auto company's offer to the union includes more than $7 billion in investments, more than 5,400 jobs, higher pay, and improved benefits.
"We have negotiated in good faith and with a sense of urgency," the automaker said in a statement. "Our goal remains to build a strong future for our employees and our business."
But union leaders said the sides are far apart on economic issues, despite some progress being made in the negotiation. "We are standing up for job security for our members and their families," Terry Dittes, director of the UAW GM department, said. He added that the the strike "represents great sacrifice and great courage on the part of our members."
