This study examines the relationship between involvement in a job-related communication network and organizational commitment. The findings indicate a complex relationship that is moderated by the degree of job involvement. For employees who are not involved in their jobs, involvement in the job-related communication network functions to foster commitment to the organization. Two major conclusions are drawn: (1) the impact of involvement in communication networks on employee attitudes and behaviors may occur only for individuals with certain characteristics; and (2) previous studies that have reported main effects for individual variables on organizational commitment may need reinterpretation in light of the disordinal interaction obtained here. The possibility that different commitment processes operate for different kinds of employees is explored, with special emphasis on those employees for whom communication is a potent factor in determining attitudes. Implications for future research on the relationship between communication network involvement and other employee responses are discussed.
