The National Labor Relations Board (NLRB) has accused SpaceX of wrongfully firing eight employees who criticized Elon Musk's tweets, calling him a 'distraction and embarrassment.' The employees' letter claimed Musk's behavior contradicted SpaceX's diversity and workplace conduct policies. The NLRB alleges SpaceX interrogated and threatened employees over the letter. A hearing is set for March 5, unless SpaceX settles. If guilty, SpaceX could face penalties and be required to reinstate the employees with back pay. This adds to Musk's labor-related controversies, including Tesla's recent changes to equity awards and a legal dispute with a former employee.
