Twitter’s former CEO Parag Agrawal, Chief Financial Officer Ned Segal, Chief Legal Counsel Vijaya Gadde and General Counsel Sean Edgett claim in the lawsuit filed Monday that they were fired without a reason on the day in 2022 that Musk completed his acquisition of Twitter, which he later rebranded X.

Because he didn’t want to pay their severance, the executives say Musk “made up fake cause and appointed employees of his various companies to uphold his decision.”

The lawsuit says not paying severance and bills is part of a pattern for Musk, who’s been sued by “droves” of former rank-and-file Twitter employees who didn’t receive severance after Musk terminated them by the thousands.
