“Nothing stopping Tesla team at our car plant from voting union,” Musk, who is no stranger to controversial Tweets, wrote on Twitter back in 2018. “Could do so tmrw if they wanted. But why pay union dues & give up stock options for nothing?”
The National Labor Relations Board ruled that Tesla broke the law by “coercively interrogating” staff who supported the union and restricting employees from talking to the media. The board also said Elon Musk’s message on Twitter “unlawfully threatened” Tesla’s employees as they “would lose their stock options if they chose the Union” to represent them.
Tesla has denied any wrongdoing, arguing that Musk’s controversial Tweet is protected by the First Amendment guarantee of free speech.
