Elon MuskSpend 40 Hours in the Office, or Else

In emails to workers at SpaceX and Tesla, Mr. Musk said they were required to spend a minimum of 40 hours a week in the office.

Mr. Musk, the world’s richest man, sent a pair of similar memos on Tuesday to push his employees at SpaceX.

The rocket company he runs, and Tesla, the electric carmaker he leads, spend time in the office.

In his email to SpaceX employees, Mr. Musk told workers that they were required to “spend a minimum of 40 hours in the office per week.

“The more senior you are, the more visible must be your presence,” Mr. Musk said.

“That is why I spent so much time in the factory — so that those on the line could see me working alongside them. If I had not done that, SpaceX would long ago have gone bankrupt.”

Mr. Musk also wrote that “anyone who wishes to do remote work” must be in the office for a minimum of 40 hours a week. Those who decline should “depart Tesla,” he added.

In his memo to Tesla’s executive staff, which was posted by two pro-Tesla Twitter accounts and which the billionaire appeared to confirm.

With his twin notes, Mr. Musk waded directly into a fractious debate over the right way for corporations to bring workers back to the office during the coronavirus pandemic.
