President-elect Donald Trump tapped Elon Musk to co-lead a new Department of Government Efficiency to reduce government spending.
At companies like X, Tesla, and SpaceX, Musk is known for modeling an intense work ethic and making drastic workforce reductions to lower costs.
When Musk took over Twitter in 2022, he ended the company's remote work policy and free office lunches.
Musk required employees to start paying for office lunches that had previously been free, told employees to expect 80-hour workweeks.
Musk cut around 50% of Twitter's staff and set an expectation for those who remained to "work 24/7."
Tesla's "Anti-Handbook Handbook" details the high bar the company sets for employees, instructing them to be self-reliant and do everything they can to solve problems, even if it means forgoing office protocol or reaching out to Musk directly.
Musk also sent a memo in 2018 advising Tesla employees to "walk out of a meeting or drop off a call as soon as it is obvious you aren't adding value."
In 2018, Musk said he spent nights sleeping on a couch and the floor at Tesla factories while the company ramped up production on the Model 3 sedan.
In April, Tesla laid off 10% of its workforce as Musk said the company needed to be "absolutely hard core about headcount and cost reduction."
In 2019, Musk laid off 10% of SpaceX employees in order to "become a leaner company," a SpaceX spokesperson previously told Business Insider.
