(Palo Alto, CA) -- It looks like the world's richest man isn't happy with Tesla executives working from home.

Elon Musk is the CEO of the electric vehicle maker. He reportedly sent an email to staff saying they must work at least 40 hours in the office or risk being fired. He's criticized other remote policies before, despite several companies allowing their employees to stay home longer or even forever.

Musk is currently in negotiations to buy Twitter.
