Musk, the CEO of companies including Tesla and X, formerly Twitter, has described himself as a "nanomanager." Consistent with that style, Musk doesn't like delegating and last year told Tesla staff he wanted to personally approve all new hires.
Musk also encourages people to leave meetings rather than stay in some cases. In a 2018 email to Tesla staff, he said there should generally be fewer, shorter meetings and wrote, "Walk out of a meeting or drop off a call as soon as it is obvious you aren't adding value."
He's also said employees can feel free to buck the chain of command to get things done.
"Anyone at Tesla can and should email/talk to anyone else according to what they think is the fastest way to solve a problem for the benefit of the whole company," he wrote in an email to Tesla staff a few years back. "You can talk to your manager's manager without his permission, you can talk directly to a VP in another dept, you can talk to me, you can talk to anyone without anyone else's permission."
