In the construction industry, the problem of worker fatigue is more than just academic. The National Safety Council in October reported that 100% of the construction workers they surveyed had at least one risk factor for on-the-job fatigue and that only 75% believed being overtired on a construction site was a safety issue. However, 98% of employers said fatigued workers did pose safety risks. And while 96% of employers said it was unsafe to drive while overly tired, only 78% of employees agreed that it was.
