New York CNN —Elon Musk publicly scoffed at a Twitter employee’s uncertainty about whether he had been laid off in a recent round of cuts and spoke dismissively of the employee’s disability in a series of tweets Monday night. Haraldur Thorleifsson, an Iceland-based Twitter senior director, tweeted at Musk that access to his computer had been cut off nine days earlier, when Twitter reportedly laid off some 200 employees. It’s not the first time Musk, one of the richest men in the world, has publicly mocked employees at Twitter, the company he bought for $44 billion last year. Hundreds of former Twitter employees are now taking legal action against the company, alleging broken severance promises and, in some cases, discrimination, including against disabled employees. Following the exchange with Musk, Thorleifsson said in a tweet that Twitter’s HR head had confirmed he is no longer employed at the company.
