Voting on a tentative contract agreement between General Motors and the United Auto Workers union that ended a six-week strike against the company appears too close to call after the latest tallies at several GM factories were announced Wednesday.

Facing the loss of another $200 million this week to a lengthy strike, General Motors CEO Mary Barra wrapped up her weekend by going to the United Auto Workers' Detroit headquarters intent on getting a new contract.

The United Auto Workers union has widened its strike against General Motors, the lone holdout among the three Detroit automakers, after reaching a tentative contract agreement with Jeep maker Stellantis.

The United Auto Workers union appears to be edging closer to a tentative contract agreement with Ford that would be critical to ending the union's 6-week-old strikes against the three major Detroit automakers, two people with knowledge of the talks said Wednesday.

First it was Ford, then Stellantis, and now a General Motors factory has been added to the growing list of highly profitable plants where the United Auto Workers union is on strike.

The United Auto Workers union has once again escalated its strikes against big Detroit automakers, this time adding a factory that makes Ram pickup trucks for Stellantis.

United Auto Workers President Shawn Fain said Friday that while Detroit’s automakers have increased their wage and benefit offers, he believes the union can gain more if it holds out longer in contract talks.

The United Auto Workers strike strategy has been mostly predictable over the last four weeks. On Fridays, the union would announce which plants would go on strike based on how well the week's negotiations went. National union leadership announced Friday that pattern is ending and local UAW officials say they'll have to calm member's nerves about it.

The United Auto Workers union significantly escalated its walkout against Detroit's Three automakers, shutting down Ford's largest factory and threatening Jeep maker Stellantis.

The United Auto Workers unions targeted strike strategy continues to result in the big three auto companies temporarily laying off workers as work stoppages slow production up and down the supply chain. General Motors workers at a plant in Marion are among the latest to feel the effects.
