 Some companies have instituted policies to allow employees to take napping breaks during the workday in order to improve productivity while others are strict when dealing with employees who sleep while on duty and use high-tech means, such as video surveillance, to catch their employees who may be sleeping on the job.Those who are caught in violation may face disciplinary action such as suspension or firing.Some employees sleep, nap, or take a power-nap only during their allotted break time at work.
