United Auto Workers union President Shawn Fain said Thursday the union has filed an unfair labor practice complaint against General Motors and Stellantis, a new sign of how far apart the union and the automakers remain as they negotiate a new contract only two weeks before a strike deadline.
The complaint accuses the automakers of not bargaining in good faith by not providing any response to the union's economic demands at the bargaining table.
"We are now 14 days out from our contract expiration and both General Motors and Stellantis have failed to give us any economic counters," Fain said in prepared remarks obtained by CNN to members on Facebook and YouTube Thursday evening.
The complaint itself has almost no legal significance at this point because it will likely take weeks, if not months, for the National Labor Relations Board to act.
The claims are more of a negotiating tactic than a legal maneuver, said Todd Vachon, professor of labor studies at Rutgers University.
"It shows there's definitely a lot of stress and tension between the two sides that there are unfair labor practice charges being filed at this point," said Vachon. "It's also a way to get members fired up."
GM and Stellantis, which makes vehicles under the Jeep, Ram, Dodge and Chrysler brands, did not immediately respond to a request for comment.
The UAW is on record with an ambitious set of bargaining demands, including raises of more than 40% over the four-year life of the next contract and the elimination of differences in pay and benefits between long-time employees hired before 2007, and those hired after.
Among those differences are a traditional defined benefit pension plan and retiree health care coverage that long-time employees currently have but that newer employees do not.
The union also objects to the even lower pay levels for workers who can remain stuck on temporary status for years. And it wants a return of the cost-of-living-adjustment that raises pay an additional amount annually based on the rate of inflation.
The UAW's contracts with GM, Stellantis and Ford all end at 11:59 pm on September 14, and the union has said it will not extend the contracts and stay on the job if tentative labor ageeements are not reached. There are 145,000 UAW members at the nation's three unionized automakers. The rank-and-file members voted overwhelmingly to authorize a strike in a vote concluded August 24.
The UAW has never struck all three automakers at the same time. But UAW President Shawn Fain, who was elected earlier this year in the first popular election held to select the union's leader, is raising the possibility this time, saying there will be no extensions granted to any of the automakers.
UAW spokesman Jim McNeill said the union did not file a complaint against Ford because that automaker has responded to union bargaining demands.
