Study: Power without status can lead to to rudeness, even abuse | CNN.com
In an article to be published in the Journal of Experimental Social Psychology, researchers studied the relationship between the status and the power of a job, said Nathanael Fast, assistant professor of management and organization at the University of Southern California's Marshall School of Business.
The study, "The Destructive Nature of Power without Status," determined that the combination of some authority and little perceived status can be toxic.
"We found that people who had high power and high status, they were pretty cool," Fast told CNN. "But it was people who had power and lacked status who used their power to require other persons to engage in demeaning behavior."
