Former Twitter executives sue Elon Musk over dismissals

A new lawsuit is the latest in a series of legal challenges billionaire Elon Musk faces after he acquired the social media company Twitter, now known as X.

Four former top Twitter executives, including former CEO Parag Agrawal, have sued Elon Musk for more than $US128 million ($A197 million) in combined unpaid severance.

The lawsuit, filed on Monday in federal court in San Francisco, is the latest in a series of legal challenges the billionaire faces after he acquired the social media company for $US44 billion ($A68 billion) in October 2022 and later renamed it X.

The other plaintiffs are Ned Segal, Twitter's former chief financial officer; Vijaya Gadde, its former chief legal officer; and Sean Edgett, its former general counsel.

Mere minutes after Musk took control of Twitter, the former executives say they were fired and that Musk falsely accused them of misconduct and forced them out of Twitter after they sued the billionaire for attempting to renege on his offer to purchase the company.

Musk then denied the executives severance pay they had been promised for years before he acquired Twitter, according to the lawsuit.

The plaintiffs say they each are owed one year's salary and hundreds of thousands of stock options.

"This is the Musk playbook: to keep the money he owes other people, and force them to sue him," the former executives said in the 39-page lawsuit.

X is already facing a pair of proposed class actions claiming it owes rank-and-file workers who were laid off after Musk's acquisition at least $US500 million ($A768 million) in severance, and a third lawsuit by six former senior managers making similar claims. X has denied wrongdoing.

The company has also been sued previously for failing to pay its former public relations firm, landlords, vendors and consultants.

X did not respond to a Reuters request for comment.
