Language as a Lightning Rod: Power Contests, Emotion Regulation, and Subgroup Dynamics in Global Teams

Through an ethnographic study comprised of interviews with and observations of 96 globally distributed members in six software development teams, we propose a model that captures how asymmetries in language fluency contribute to an us vs. them dynamic so common in global teams. Faultlines, formed along the dimensions of asymmetries in the degree of fluency of team members, location, and nationality, were associated with subgrouping in some, but not all of the teams. Our findings suggest that divisive subgroup dynamics only occurred in teams that also suffered from power contests, suggesting power contests activate otherwise dormant faultlines. Language asymmetries further acted as a lightning rod such that team members' emotional responses to them were constant reminders of subgroup differences on these teams, which further fueled negative emotions. Our findings extend theory on subgroup dynamics in global teams by adding language as a potential faultline, showing how power struggles activated faultlines and were, in turn, reinforced by them, and documenting the emotion regulation processes triggered by subgrouping and enacted through language-related choices and behaviors.
