"Hundreds of Twitter's remaining employees have reportedly resigned ahead of Elon Musk’s “extremely hardcore” cultural reset of the company. After Musk gave an ultimatum to his employees to either commit to the company’s new “hardcore” work environment or leave, many more workers declined to sign on than he expected, potentially putting Twitter’s operations at risk, according to Bloomberg sources, as well as internal Slack messages seen by The Verge and employee tweets. On Thursday afternoon, so many employees decided to take severance that it created a cloud of confusion over which people should still have access to company property. According to a memo seen by Bloomberg and reports from Platformer's Zoe Schiffer, Twitter closed its offices until Monday; urging employees to “please continue to comply with company policy by refraining from discussing confidential information on social media, with the press or elsewhere." According to Bloomberg, in the final hours before his deadline, Musk tried to convince people to stay. Key staff were brought into meetings as the Thursday evening deadline neared to hear pitches on the social network’s future, according to people familiar with the matter. Musk, who had earlier said he was strictly against remote work, also sent a follow-up email Thursday softening his tone."
