Sleeping on the job isn't a firing offense. In fact, it's a behavior you probably should be encouraging.

Maybe this isn't news to you. Maybe you've read a couple of posts or articles before noting that naps actually boost employee performance and that it would behoove rational employers to let their tired employees snooze. But maybe you're just too irked by the idea of seeing somebody you're paying good money snoring away to actually implement this idea. If so, new research gives you even more reason to get with the napping program.

To kick things off, let's recap what science has already discovered about naps.

So basically, if you could put a nap in a bottle, it would be a wonder drug. Which probably should be enough to convince you to view that slumbering employee as a productivity ninja rather than a slacker, but if you need even more convincing, yet another study on the benefits of napping just came out.

This one, out of the University of Michigan, looked at how a short nap affected the emotional control of 40 adults. It found that "taking a nap may be an effective strategy to counteract impulsive behavior and to boost tolerance for frustration," the research release notes.

So in other words, napping not only makes your brain and body work better, it also makes you less cranky. That's not a surprising finding exactly (any parent or kindergarten teacher could tell you the same thing), but in a world where we could all use a little more civility at work, it's worth reminding ourselves that tired employees are generally not the kindest or most patient employees.

The release concludes: "Employers may find their employees more productive when the workplace has nap pods in the workplace or extended break times are offered." Besides offering these accommodations to help your tired employees recharge, you might also want to familiarize yourself with the science on how to take an optimal nap.

Given all this research, are you finally ready to get with the napping program?
