Many business leaders still believe that time on-task equates to productivity. However, studies have shown that shorter amounts of sleep lead to both lower efficiency and slower completion of basic tasks. That is, sleepy employees are unproductive employees, and they generate fewer and less accurate solutions to problems.
Many people don't understand that when you are not getting enough sleep, you work less productively and thus need to work longer hours to accomplish a goal, creating a negative feedback loop.
