(CBSNEWS) — If you happen to be at work right now and you’re feeling tired, you’ve got a lot of company. A new CDC study finds more than 40 million workers get fewer than six hours of sleep per night – that’s about 30 percent of the country’s civilian workforce.

And by not getting the National Sleep Foundation’s recommended seven to nine hours of shut-eye per night, the CDC says these workers pose a serious and potentially fatal risk to themselves and coworkers. The CDC’s study is published in the April 26 issue of its journal Morbidity and Mortality Weekly Report.

Some workers were hit harder in their slumber time, the survey of more than 15,000 workers found. Forty-four percent of night-shift workers reported not getting enough sleep with rates highest among workers in the transportation or warehouse industries, followed by health care and social assistance workers.
