A study conducted by two Harvard professors tracked 27 CEOs (25 men and 2 women). They gathered CEO statistics that measure what CEOs actually do all day. It was discovered that on average, CEOs worked 9.7 hours per weekday and 3.9 hours over weekend days.
They have rigorous schedules of which 75% has to be planned ahead and only 25% are spontaneous. An average percentage of 25 was spent on personal downtime, 29% on sleeping, 31% spent working, 10% traveling, and 5% on vacation. It’s important for most CEOs to get a decent amount of sleep, clocking at least 6-7 hours per night.
