The United Auto Workers union on Monday ordered 6,800 members to strike at Stellantis' largest assembly plant, halting output of the auto maker's profitable Ram 1500 pickup.
"Stellantis has the worst proposal on the table regarding wage progression, temporary worker pay and conversion to full-time, cost-of-living adjustments (COLA), and more," the union said in a statement.
The Sterling Heights Assembly Plant north of Detroit is Stellantis' only source of the current-generation Ram 1500.
The abrupt move is the UAW's first expansion of the strike since Oct. 11, when it added Ford Motor Co.'s Kentucky Truck Plant. That plant builds Super Duty pickups as well as the Ford Expedition and Lincoln Navigator large SUVs.
More than 40,000 UAW workers are now on strike.
“We’ve had talks through the weekends,” UAW President Shawn Fain told WXYZ Channel 7 in Detroit. “We just felt like it was time to turn it up.”
“They know where we need to be,” Fain said. “We can get there. We can get a deal done this week. But the company’s got to get serious and get down to business.”
Stellantis issued a blistering response:
"We are outraged that the UAW has chosen to expand its strike action against Stellantis ... The UAW’s continued disturbing strategy of 'wounding' all the Detroit 3 will have long-lasting consequences. With every decision to strike, the UAW sacrifices domestic market share to non-union competition. These actions not only decrease our market share, but also impact our profitability and therefore, our ability to compete, invest and preserve the record profit sharing payments our employees have enjoyed over the past two years."
