The National Labor Relations Board (NLRB) has claimed that SpaceX illegally terminated eight employees who circulated a letter critical of CEO Elon Musk’s public behavior.

The New York Times reports that the National Labor Relations Board (NLRB) has made serious allegations against SpaceX, the space transport services company led by CEO Elon Musk. In a recent filing, the NLRB claims that SpaceX wrongfully terminated eight employees who had been vocal in their criticism of Musk’s public conduct. These employees had distributed a letter internally, which pointedly criticized Musk’s behavior on social media, particularly focusing on his handling and response to sexual harassment allegations against him.

The letter called for the company to take a clearer and more consistent stance on harassment issues. It specifically requested the enforcement of policies that would prevent similar incidents and foster a safer, more respectful work environment. However, instead of addressing these concerns, SpaceX is accused of retaliating against the employees involved by terminating their employment. This move, according to the NLRB, is a violation of federal labor laws that protect employees’ rights to engage in concerted activities for mutual aid and protection.
