SpaceX faces a complaint from the National Labor Relations Board, alleging the company unlawfully terminated eight employees who criticized CEO Elon Musk in a letter. The employees cited Musk's controversial tweets as contradictory to company values. The complaint includes accusations of SpaceX interrogating and threatening employees involved in the letter. The case, if not settled, will proceed to a hearing and potentially lead to reinstatement and back pay for the affected employees, along with possible future penalties for SpaceX.
