No, not really. Tesla + SpaceX have ~25,000 employees. While Musk is without a doubt a hard charger, always pushing his employees, it's a pretty big leap to suggest those 25,000 employees are all working 80 hours per week, sleeping under their desks, and can't walk their dogs in the afternoon.
Here's the actual reality: 99% of those 25,000 employees are on normal work schedules, with normal work expectations. There are no organizations of that scale in the US where the employees all work crazy hours and sleep under their desks; quite the opposite, organizations that large always drift toward the middle by necessity (they can't attract tens of thousands of workers in a highly competitive labor market otherwise).
