According to the U.S. Bureau of Labor Statistics, during 2013 employed Americans "worked an average of 7.6 hours on the days they worked," and "83% did some or all of their work at their workplace" [1]. Understanding processes in the workplace has been the subject of disciplines like organizational psychology and management for decades. In particular, the study of nonverbal communication at work is fundamental as "face-to-face interaction with superiors, subordinates, and peers consumes much of our time and energy" [2] and a variety of phenomena including job stress, rapport, and leadership can be revealed by and perceived from the tone of voice, gaze, facial expressions, and body cues of coworkers and managers [2]. ©2015IEEE.
