According to a new National Safety Council survey-based report, 43% of Americans say they do not get enough sleep to mitigate critical risks that can jeopardize safety at work and on the roads, including the ability to think clearly, make informed decisions and be productive. Eighty-one percent of the probability-based survey respondents have jobs that are at high risk for fatigue— positions that require sustained attention or are physically or cognitively demanding, such as driving a vehicle or working at a construction site, according to the report, Fatigue in the Workplace: Causes & Consequences of Employee Fatigue.

The survey found 97% of Americans say they have at least one of the leading nine risk factors for fatigue, which include working at night or in the early morning, working long shifts without regular breaks, working more than 50 hours each week, and enduring long commutes. Seventy-six percent of Americans say they feel tired at work, 53% feel less productive, and 44% have trouble focusing. Fatigued employees are more likely to make safety critical errors that could lead to injury, such as crashing their vehicle.

“These findings are a literal wake-up call: When we’re tired, we can put ourselves and others at risk,” says Deborah A.P. Hersman, president and CEO of the National Safety Council, in a release. “We hope Americans recognize that impairment stems not just from alcohol and drugs, but lack of restorative rest—fitness for duty starts with getting a good night’s sleep.”

The survey – the entirety of which will be released in three separate reports – also found:

  • 41% work high-risk hours, at least occasionally.
  • 39% have trouble remembering things at work because of fatigue.
  • 31% commute 30 minutes or more, which exacerbates the chances of falling asleep behind the wheel.
  • 27% have trouble making decisions because of fatigue.
  • 10% do not get regular rest breaks.
  • There are geographical trends when it comes to the number of Americans with fatigue risk factors. This survey identified that the South has the highest mean number of risk factors at 3.21, while the Midwest has the lowest with 2.94 risk factors.
