Musk sent an email to Twitter employees earlier this week demanding they commit to working long hours at high intensity or clear their desks by Thursday, November 17.
According to reports, a large number of them have chosen the second option, which includes three months' severance pay, causing the company to close its offices as hundreds of employees walked out temporarily.
Twitter also announced that all badge access would be temporarily suspended until Monday, November 21 and that employees should refrain from discussing confidential company information on social media, with the press, or elsewhere.
According to a poll of 180 people on the workplace app Blind, 42% chose the answer "Taking exit option, I'm free!" on Nov. 18. In a separate poll, half of those polled predicted that half of the staff would leave.
Employees aren't the only ones leaving Twitter in Musk's wake; users are also looking for alternatives. Mastodon, for example, has recently seen an increase in new registrations.
The decentralized social network is a network of interconnected, independently operated servers that run open-source software.
Mastodon announced on November 12 that it had gained over a million new members since the Twitter acquisition was completed. MIT reported on November 3 that Twitter had lost the same number of users since Musk's purchase.
Former Twitter Ceo Dorsey hopes that his Bitcoin-powered platform will entice users away from the centralized, scam- and spam-infested Web2 social media platforms.
Dorsey has already refused to accept the CEO position at Twitter, citing Musk's recent statement that he prefers someone else to lead the company.
Meanwhile, after learning of the employee exodus, Elon Musk lamented the difficulties of running a social media network.
Musk responded in a separate tweet to the founder of the pop culture blog Barstool Sports, Dave Portnoy, saying he was not super worried because the best people were staying.
