behavior on the job.

Early 2011 saw a spate of reports in the media about air traffic controllers sleeping on the job as a result of sleep deprivation. The potential harm from this behavior is obvious, but what about the average office job? Can sleep deprivation cause counterproductive, or even unethical, behavior in organizations?

“Over the past decade, Americans have been getting less and less sleep and estimates are that this trend will continue,” said Professor of Management and Organizations Aleksander Ellis, the Charles and Candice Nelson Fellow. “In fact, in certain industries, lack of sleep is worn as a badge of honor.”

In a recent paper published in the Academy of Management Journal, Ellis and coauthor Michael Christian of Kenan-Flagler Business School at the University of North Carolina-Chapel Hill demonstrate that lack of sleep can cause deviant behavior.

In one part of the study, for instance, the researchers asked a group of subjects to respond to an email that contained colloquial language and misspellings. One of the sleep-deprived subjects responded with an unprofessional, personal attack, just one example Ellis and Christian cite to demonstrate how sleep deprivation reduces self-control and increases hostility.

Ellis and Christian are currently working on a parallel project that examines how sleep deprivation affects the tendency of individuals to behave unethically by conforming to the behavior of unethical authority figures.

The work is part of a research agenda supported by the Center for Leadership Ethics at the Eller College of Management.
