Elon Musk doubled down on Tesla employees who continue to resist his order to return to the office full-time.

In a second email to employees, Musk clarified that executives and other workers will be fired if they don't return to their desks after their 2-year vacation at home.

The internal company email, shared by Twitter user @SamNissim, bears the subject line "To be super clear."

"Everyone at Tesla is required to spend a minimum of 40 hours in the office per week. If you don’t show up, we will assume you have resigned."

Musk made it clear to his executives: "The office must be where your actual colleagues are located, not some remote pseudo office."

"The more senior you are, the more visible must be your presence," Musk wrote, before adding that he slept in a Tesla factory to boost his workers' morale.

"That is why I lived in the factory so much - so that those on the line could see me working alongside them. If I had not done that, Tesla would long ago have gone bankrupt."

Musk then declared: "If you don't show up, we will assume you have resigned."

To those still complaining about returning to work, Musk suggested they find employment elsewhere.

"There are of course companies that don't require this, but when was the last time they shipped a great new product? It's been a while. Tesla has and will create and actually manufacture the most exciting and meaningful products of any company on Earth. This will not happen by phoning it in."

Musk has been vocal about his disapproval of remote work in the past. Corporations and small businesses allowed employees to work from home at the start of pandemic in 2020.

Some employees - believing that remote work would last forever - moved out of state and bought homes as far away as Florida.
