Go "hardcore" or leave, Musk tells Twitter

Musk told Twitter employees that anyone who had not clicked on a link confirming "you want to be part of the new Twitter" by Thursday evening New York time would be considered to have quit.

A copy of the message, which was reported by The Washington Post, was reviewed by Reuters. Three sources who had received the message at Twitter confirmed its content.

Twitter did not immediately respond to a request for comment from Reuters.

The latest move to restructure the company comes after Twitter slashed half of its workforce earlier this month as Musk took control of the social media company.

Musk has criticised Twitter's spending and work culture, and said that the company needs steep cost cuts and a reboot of its services.

"Going forward, to build a breakthrough Twitter 2.0 and succeed in an increasingly competitive world, we will need to be extremely hardcore," the message from Musk said.

"This will mean long hours at high intensity. Only exceptional performance will constitute a passing grade."

Musk said Twitter would be "much more engineering-driven" under his leadership, adding that "those writing great code will constitute the majority of our team and have the greatest sway."

The billionaire CEO of Tesla Inc has taken to cost cutting with a vengeance.

Even after mass lay-offs - which forced it to attempt to offer some employees in critical divisions to return - some employees on Tuesday said they had been fired, which they suspected was due to posting critical comments of the company or Musk on Twitter or its internal message platform.

Musk called himself a "free speech absolutist" when he pursued the Twitter purchase.

One source told Reuters they received a termination email overnight that stated that "your recent behaviour has violated company policy," adding that he believes that over 20 people were fired in the latest round. Several others tweeted on Tuesday that they had received the same emails.

"I would like to apologise for firing these geniuses," Musk tweeted on Tuesday. "Their immense talent will no doubt be of great use elsewhere."

Last week, in his first company-wide email, Musk said remote work would no longer be allowed and that employees would be expected in the office for at least 40 hours per week, while warning that Twitter may not be able to "survive the upcoming economic downturn."

He also told employees that if "you do not show up at the office, resignation accepted," according to a transcript of a meeting reported by Verge.

Meanwhile, Musk faced a Delaware court on Wednesday to rebut claims that his $56 billion Tesla pay package was based on easy performance targets and approved by a compliant board of directors.
