Coworker communication is defined as the communication between two individuals of equal organizational status, neither of which has authority over the other. While still understudied, the importance of coworker communication in workers' health, productivity, and organizational functioning is increasingly acknowledged. Peer coworker communication serves several vital functions in organizations, such as organizational socialization, peer mentoring, and social support. Common topics of peer coworker communication research include bullying, friendship, and romance. While peer coworker communication is studied from a variety of methodological and theoretical perspectives, future directions in this area of research are plentiful. Future research can further explore nuances of peer coworker friendship and romance, the impact of technology on coworker communication, the dark functions of coworker communication, and the influences of (and on) specific organizational communication variables, such as trust and identification.
