The study appearing in the CDC's Morbidity and Mortality Weekly Report found many are getting fewer than six hours of sleep every night, putting themselves and their co-workers at risk for serious and sometimes deadly consequences.
The recommended amount of sleep for adults is seven to nine hours a night.
Transportation workers were among those getting the least amount of sleep and those who work the night shift are more likely to not get enough sleep.
Also, people who work more than one job or more than 40 hours a week are likely to get too little sleep.
