An email from Elon Musk to certain Tesla employees caused a lot of reaction. In a missive sent to company executives on Tuesday, which the MailOnline obtained a copy of, Musk said working from home “is no longer acceptable”.

“Anyone who wants to work remotely must be present in the office at least 40 hours a week (I say a minimum of 40 hours). This is much less than what we ask of factory workers”, expresses the richest man in the world in the email sent to the executives.

He specifies that exceptional employees for whom it is impossible to come to the office could be exempted from the measure, permissions which he will personally authorize.

"Furthermore, 'the office' must be a Tesla office, not a remote branch that is unrelated to the duties of the position. For example, being responsible for human resources in Fremont, but having your office in another state, ”says the richest man in the world in his missive.

He also added on Twitter, when a user asked him if the concept of working in the office was not obsolete.

Musk simply replied, "They should pretend to work somewhere else."

Last month, Musk, who is currently negotiating with Twitter to buy the social media giant, apparently took aim at the company's lax remote working policies.

He said he asked his Twitter followers if he should turn the company's Silicon Valley headquarters into a homeless shelter "since no one is showing up anyway."

Google recently also asked its employees to return to face-to-face, at least three days a week. Apple, which wanted the same, ultimately delayed its return-to-work plans due to a spike in COVID cases in California.
