Elon Musk laid down a deadline of 5pm today to Twitter’s remaining employees to commit to “extremely hardcore” work, or jump ship.

“This will mean working long hours at high intensity,” Musk wrote in a memo to staff this week. “Only exceptional performance will constitute a passing grade.”

If they don’t respond by the deadline they can walk with 3 months of severance pay. This comes after a mandate to return to the office full-time.

In a separate email to staff earlier this month, he warned that “there is a good chance Twitter will not survive the upcoming economic downturn” without “significant” subscription revenue.
