When managers lose sleep, their employees’ experiences and output are diminished too, reports Harvard Business Review.

One additional—perhaps more powerful—finding from this research was that leaders’ devaluation of sleep may also cause followers to behave less ethically. Bosses who systematically eschewed rest—in comparison to other managers—rated their subordinates as less likely to do the right thing. We suspect this wasn’t just a matter of the sleep-deprived leaders’ giving tougher ratings; it’s likely that employees were actually behaving in less moral ways as a result of the workplace environment or their own sleep deprivation.
