Earlier this week, Elon Musk gave an ultimatum to the remaining employees of Twitter. In an email sent out to the company, Musk said that workers must adapt to a new “extremely hardcore” Twitter that involves “working long hours at high intensity” and where “only exceptional performance will constitute a passing grade.” The alternative is to leave the company. The email included a link, in which those wishing to continue working must click by 1700 EST on Thursday.

At the time of the email, only about 3,700 Twitter employees remained, which is about half of what was before Musk came on as CEO. While some quit, many were laid off, which Musk said was due to decreased revenue because of companies pulling advertisements.

I say this several times in the thread but once more for good measure — we still don't know officially how many people have officially resigned. https://t.co/LlShQPTsle

Shortly after the email deadline, tech journalist Kylie Robinson Tweeted that “What I’m hearing from Twitter employees; It looks like roughly 75% of the remaining 3,700ish Twitter employees have not opted to stay after the ‘hardcore’ email.” She did explain after, however, that the exact number of employees that did not respond to the email and will resign is unknown at this time and will likely be less than that. But, if what she heard from employees is correct and accurate, about 10 percent of the company employees will remain after this.

Robinson also reported that there has not been any official communication’s by the company about the deadline since its passing and that employee badge access has been disabled to offices until Monday. A code freeze is also in effect, meaning developers cannot work on the app.

Musk’s only tweet from his personal account in the past 10 hours, which was posted about 30 minutes from writing this article, reads “How do you make a small fortune in social media? Start out with a large one.” This comes as #RIPTwitter and #GoodbyeTwitter trend on the platform.
