Mechanisms for Employee Mobility Between Organizations: A Network Analysis of Faculty Turnover in Communication, 2013 to 2022

Organizations compete for scarce resources such as talent. The mobility of employees between organizations means that the inflow side acquires resources at the expense of the outflow side. This study understands employee turnover from one place to another as a mobility network where directed edges indicate migration flows between organizations. Using observational data on the turnover of tenure-line communication faculty in 129 U.S. universities from 2013 to 2022, this paper investigates the formation mechanisms of the interorganizational mobility network. The results show that the creation of migration flows is driven by transitive closure, but not by cyclic closure. Community cohesion is not a driving force of network formation. While low-prestige universities are more likely to be sources of faculty mobility than high-prestige universities, migration flows are commonly observed between organizations with similar levels of prestige. Additionally, the probability of faculty mobility between universities first decreases and then increases with their geographic distance.
