A leaked email from Tesla CEO Elon Musk to office employees revealed that remote work will no longer be an option at the company.

Musk responded Wednesday on Twitter to confirm the authenticity of the email he sent on Tuesday. He also reaffirmed his stance on remote work; anyone who wishes to work remotely for Tesla should quit.

According to the email posted to Twitter, Musk emailed "ExecStaff" with the subject line "Remote work is no longer acceptable." The world's richest man, with a net worth of $218.1 billion, emailed the office staff at around 1 p.m. PT on Tuesday.

The email emphasizes that "anyone who wishes to do remote work" needs to be in the office a "*minimum*" of 40 hours per week. "This is less than we ask of factory workers," he added.

The South African-born entrepreneur wrote that those who find this unacceptable should "depart Tesla," adding that any exceptions be "directly" subject to his approval.

Musk also called out those who work from another state. "The 'office' must be a main Tesla office, not a remote branch office unrelated to the job duties," he clarified.

The rise in popularity of remote work means anyone can work from anywhere, even if company headquarters are in another state or country. Some experts call it "the great reshuffle" of U.S. workers.

The CEO’s more recent antics caused problems for Tesla amid Musk’s bid for Twitter. Questions remain about whether the deal will continue. Some wonder if Musk will walk away or if Twitter sticks to its guns and demands a deal.

As of Tuesday at 10:45 a.m. ET, Tesla stock was valued at $748.40, down $9.87 or 1.30%.
