President Joe Biden has long praised organized labor, declaring at an event earlier this month that "the middle class built America, and unions built the middle class."

However, despite Biden's professed support for union members, a new report suggests that some in the movement have stopped supporting him. 

Frustration over Biden's record

Politico published an article on Friday about the dispute between by United Auto Workers (UAW) and GM, Ford, and Stellantis, known collectively as "The Big Three" automakers.

Fox Business reported that work stopped at a GM plant in Wentzville, Missouri, a Stellantis plant in Toledo, Ohio, and a Ford plant in Wayne, Michigan after union and corporate negotiators couldn't agree to a new contract on Thursday night.

Meanwhile, UAW president Shawn Fain has said that those members who are employed at other facilities will continue working without a contract for now.

Politico interviewed union workers in Fain's hometown of Kokomo, Indiana, they expressed frustration with President Biden.

UAW official: "I don't know what he's done"

"I don't know what he's done," local UAW president Garry Quirk was quoted as saying. "Ask him. I don’t think he knows what he’s done. Seriously. I’m not trying to be mean."

Fellow UAW official Denny Butler wasn't impressed either, saying, "We haven’t had a president in there for years, with the exception of Trump, that was really for the people, all the way back to the Reagan days."

"Historically, man, if you didn’t vote Democrat years ago, and you were in the union, sometimes you got your ass kicked," Butler explained.

"Democrats were for the working people. That s--t has changed. I’m telling you what, the Democratic Party was not what it was 20, 30 years ago," he insisted.

Trump calls for end to electric vehicle mandates

While union committeeman Dave Johnson is not supportive of Donald Trump, he also has no love for Biden and does not plan to vote for the president next year.

"Terrible," Johnson said of Biden. "Can’t remember his own name. It needs to be someone else besides those two guys. I’d vote for Obama."

Politico observed how Fain and the UAW have yet to endorse Biden, something which has thrown "into doubt Biden's standing in autoworker-heavy communities like his."

Fox News noted that for his part, Trump recently called on auto workers to demand an end to the Biden administration's electric vehicle, insisting they are "disastrous" and will cause the auto industry to "cease to exist."
