A former human resources boss at Twitter has accused the company of failing to pay roughly $500m (£385m) in severance pay owed to former staff of the company.
Courtney McMillian, who was the social media site’s former “head of total rewards”, made the claim in a class-action lawsuit.
The complaint says Twitter owner Elon Musk knew about the severance plan before he sacked thousands of staff.
But it says he balked at the “expense”.
It is the latest of multiple lawsuits filed against the company over the mass firings that followed Mr Musk’s purchase of Twitter for $44bn (£34bn) last year.
The layoffs ultimately affected roughly 6,000 people, according to the lawsuit.
Under Twitter’s severance plan, staff were due to receive a minimum of two months base salary in severance and a cash contribution toward health insurance, among other benefits, according to the complaint filed in federal court in San Francisco.
Those with more senior roles, including Ms McMillian, were due six months base salary in severance pay, plus one week for each full year of experience, it says.
