Eight out of ten employees - security guards, nurses, teachers and office workers, admit that one to four in the morning and afternoon are the sleepiest hours. Model employees try to resist sleep. They would try to keep doing their work then discover themselves dozing off.
Some companies understand the value of sleep. They give ten to fifteen minute nap allotment to their employees. These companies believe that a few minutes break can help an employee freshen up to do their work better.
