A federal appeals court on Friday said it will reconsider its recent decision that Tesla Chief Executive Elon Musk violated federal labor law by tweeting that employees would lose stock options if they joined a union. The 5th U.S. Circuit Court of Appeals in New Orleans granted Tesla's request to revisit the case "en banc," meaning that its 16 active judges will take part. A three-judge panel of the same court had in March upheld a National Labor Relations Board ruling that Musk's May 20, 2018 tweet was an unlawful threat that could discourage unionization at his electric car company, and must be deleted.
