NEW ORLEANS — A federal agency was wrong to order that Tesla CEO Elon Musk delete a 2018 social media post that union leaders saw as a threat to employee stock options, a sharply divided federal appeals court has ruled.
The case involved a post made on what was then known as Twitter during United Auto Workers organizing efforts at a Tesla facility in Fremont, California. The post was made years before Musk bought the platform, now known as X, in 2022.
On May 20, 2018, Musk tweeted: “Nothing stopping Tesla team at our car plant from voting union. Could do so tmrw if they wanted. But why pay union dues and give up stock options for nothing? Our safety record is 2X better than when plant was UAW & everybody already gets healthcare.”
The National Labor Relations Board said it was an illegal threat. After Tesla appealed, three judges on the 5th U.S. Circuit Court of Appeals in New Orleans upheld that decision, as well as a related NLRB order that Tesla rehire a fired employee, with back pay.
But Tesla sought a rehearing, and the full 5th Circuit later threw out the earlier decision and voted to hear the matter again. In an opinion dated Friday, the judges split 9-8 in favor of Tesla and Musk.
“We hold that Musk’s tweets are constitutionally protected speech and do not fall into the categories of unprotected communication like obscenity and perjury,” the unsigned opinion said.
The majority also found the NLRB must reconsider its order that the fired employee be reinstated, saying there was no proof that the person who fired the worker acted out of ill will toward the union.
The 11-page opinion was followed by a 30-page dissent on behalf of eight judges, written by Judge James Dennis.
“Relevant here, the Supreme Court has consistently held that the First Amendment does not protect threatening, coercive employer speech to employees in the labor organization election context— the precise category of speech Musk disseminated via Twitter,” Dennis wrote.
He also argued that the attitude of the supervisor who fired the worker was not relevant to whether he should be reinstated. The worker, Dennis wrote, “was fired for declining to divulge information about protected union activities during an interrogation.”
The ruling sent the case back to the NLRB for further action. It was not immediately clear if there would be an appeal to the U.S. Supreme Court.
The union didn’t respond to a question from The Associated Press asking about its next move. But on Tuesday night, President Shawn Fain cited the case in an online address to rally union members to vote and take part in the electoral process.
Musk, he said, has poured millions into Republican Donald Trump’s presidential campaign.
“It’s no coincidence that Elon Musk is one of the most anti-union auto CEOs in history, and he is buying elections to rig the law in his favor,” Fain said. “That’s what happens when the billionaire class makes the rules. And that’s what happens when working class people stay on the sidelines.”
