Elon Musk's erratic behavior was front and center again this week as the CEO of Tesla conceded that he's overwhelmed by job stress, pushing his electric car company's stock down and bringing pressure on its board to take action.
Musk's revelation, in a Thursday interview with The New York Times, came as government regulators are reportedly investigating whether his recent out-of-the-blue tweet about taking Tesla private violated disclosure requirements.
Now, experts say Tesla has reached an intersection where the board must decide the direction of its leadership. Among their suggestions: Remove Musk as CEO, permanently or via a temporary leave of absence, or appoint a No. 2 executive who could act as a steadying hand.
"It's kind of bizarre," said Charles Elson, director of the corporate governance center at the University of Delaware. "It's a drama we shouldn't be watching."
Tesla presents plenty of challenges for the top executive: It routinely loses money and is burning through cash as it ramps up development of its Model 3 sedan, a less-expensive electric car it hopes appeals to the mass market. A large number of investors known as short-sellers have bet against the company.
Musk has added to those pressures with lofty projections for profits and production that Tesla often fails live up to. Plus, the eccentric billionaire is the head of at least two other companies, including the rocket company Space X.
Musk admitted to the Times that the past year has been the most "difficult and painful" of his career. The newspaper reported that during an hour-long telephone interview on Thursday, an emotional Musk acknowledged that he was working up to 120 hours a week and sometimes takes Ambien to get to sleep.
Yet he said he has no plans to give up his dual role as Tesla's chairman and CEO.
