The United Auto Workers union and General Motors remain far apart in ongoing negotiations in Detroit, raising the likelihood of a midnight strike, sources told The Post on Saturday night.

UAW leaders are negotiating with GM at the Detroit Marriott, but have reached an “impasse” on health care, according to one source close to the UAW.

The union isn’t likely to postpone a strike past the midnight deadline, when the current four-year contract will expire, because the sides are so far apart on the issue of health care, the source said.

Health care “is the aspect that has bridged the greatest divide,” the source said.

Another area where there’s an impasse is job security.

“Job security remains an issue as it relates to possible plant closures,” the source said.

“While we are fighting for better wages, affordable quality health care, and job security, GM refuses to put hard working Americans ahead of their record profits,” union Vice President Terry Dittes said in a statement Saturday night.

General Motors spokesman Patrick Morrissey said in a statement, “We continue to work hard on solutions to some very difficult challenges.

“We are prepared to negotiate around the clock because there are thousands of GM families and their communities– and many thousands more at our dealerships and suppliers – counting on us for their livelihood. Our goal remains on building a strong future for our employees and our business.”
