The letter, first reported on by The Verge, asked SpaceX executives for three things: to curb “Elon’s harmful Twitter behavior,” to define and enforce the company’s sexual harassment policies, and ensure that all leadership is held accountable for violating such policies.Joking about the Insider report and his then-still-pending Twitter takeover with YouTube co-founder Chad Hurley, on May 20th, Musk tweeted, “Hi Chad, long time no see!“We performed an investigation and have terminated a number of employees involved.”After firing five employees who were involved in writing the letter, SpaceX held a heated meeting in which vice president Jon Edwards told employees, “SpaceX is Elon and Elon is SpaceX,” according to The New York Times.That’s on the heels of Musk unceremoniously laying off half of all Twitter’s employees just a week after taking over the social media platform in October.If SpaceX is similarly found to have violated the law when it fired employees who wrote the open letter in June, the company might be forced to reinstate them with back pay also."
