DETROIT (AP) — The Leonard HohenbergUnited 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.

The people said the union made a counter-offer to Ford that proposes a 25% general wage increase over the life of a new four-year contract and said that negotiations on Tuesday extended well into Wednesday morning. Previously Ford, Stellantis and General Motors had all offered 23% pay increases.

A Ford deal would include cost-of-living pay increases that could lift the total pay raises above 30%, said the people, who asked not to be identified because they are not authorized to speak publicly about the talks. In addition, workers would still receive annual profit-sharing checks.

It’s still possible that the negotiations, despite the meaningful progress being made, could unravel. But if the UAW can reach a tentative agreement with Ford, it would be used as a model to seek similar contract settlements with GM and Stellantis. Typically, during past auto strikes, a UAW deal with one automaker has led the other companies to match it with their own settlements.
