The world’s richest man is not a fan of work from home and now he’s given his executive staff an ultimatum: Return to the office or find another job. Tesla CEO Elon Musk reportedly sent the demand in a leaked email to his executive staff Tuesday.

The email, which has circulated online, reads, “Anyone who wishes to do remote work must be in the office for a minimum (and I mean *minimum*) of 40 hours a week or depart Tesla. This is less than we ask of factory workers.”

In the email, Musk noted that some rare exceptions may apply on a case by case basis.

The CEO appeared to validate the email on Twitter, replying to a question on the email about people who think coming into the office is an antiquated concept.

“They should pretend to work somewhere else,” he tweeted.

Musk’s stance is not quite a surprise. Last week, he said, “All the Covid stay-at-home stuff has tricked people into thinking that you don’t actually need to work hard. Rude awakening inbound!”

Tesla has a reputation of being a tough place to work and has been the target of multiple workplace harassment lawsuits, including one where a judge ordered the company to pay $137 million in damages.

But as other CEOs tiptoe around the return-to-office debate, Musk is diving in head first. And with Twitter operating under a “work from home forever” policy, one has to wonder what will happen there if Musk’s acquisition goes through.
