SpaceX and its chief executive, Elon Musk, were sued on Wednesday by eight engineers who say they were illegally fired for raising concerns about alleged sexual harassment and discrimination against women, their lawyers have said. The eight engineers include four women and four men and claim that Musk, who owns the rocket-maker, the electric carmaker Tesla and the social media platform Twitter/X, ordered their firing in 2022. The dismissals came, they say, after they sent around a letter calling the billionaire a “distraction and embarrassment” and urging executives to disavow sexually charged comments he had made on social media. The lawsuit was filed in state court in Los Angeles, according to the lawyers, Anne Shaver and Laurie Burgess. The lawsuit says Musk’s conduct fostered a “pervasively sexist culture” at SpaceX, where female engineers were routinely subjected to harassment and sexist comments and their concerns about workplace culture were ignored. “These actions … had the foreseeable and actual result of offending, causing distress, and intruding upon plaintiffs’ wellbeing so as to disrupt their emotional tranquility in the workplace,” the plaintiffs said in the lawsuit. SpaceX did not immediately respond to a request for comment. SpaceX has denied wrongdoing, saying the 2022 letter was disruptive and the workers were properly fired for violating company policies. The suit dropped the same day the Wall Street Journal reported that Musk had had sex with a SpaceX employee who reported directly to him and that Musk had dated a woman 20 years his junior soon after she interned at SpaceX. He asked another woman at the company to have his babies, the Journal reported. Previously, a SpaceX flight attendant alleged he exposed himself to her and offered to buy her a horse in exchange for sex. Paige Holland-Thielen, one of the plaintiffs, said in a statement provided by her lawyers that Wednesday’s lawsuit was an attempt to hold SpaceX leadership accountable and spur changes in workplace policies. “We hope that this lawsuit encourages our colleagues to stay strong and to keep fighting for a better workplace,” she said. The eight engineers are already the focus of a US National Labor Relations Board (NLRB) case claiming that their firings violated their rights under US labor law to advocate for better working conditions. SpaceX filed a lawsuit claiming that the labor board’s in-house enforcement proceedings violate the US constitution. A US appeals court last month paused the NLRB case while it considers SpaceX’s bid to block it from moving forward pending the outcome of the company’s lawsuit. Wednesday’s lawsuit accuses SpaceX and Musk of retaliation and wrongful termination in violation of California law, and further accuses the company of sexual harassment and sex discrimination. The plaintiffs are seeking unspecified compensatory and punitive damages and an order barring SpaceX from continuing to engage in its allegedly unlawful conduct.
