When Interteam Conflict Spirals into Intrateam Power Struggles: The Pivotal Role of Team Power Structures

Organizational teams frequently come into conflict with one another over limited resources. Core theories of intergroup conflict suggest that such interteam resource conflicts unite teams internally, reducing intrateam power struggles. However, conflict spillover theory suggests that interteam conflicts may also stimulate competitive power dynamics within teams. We reconcile these two opposing lines of thought by introducing the internal power structure of teams as the key moderator that determines whether interteam conflict reduces or promotes power struggles within teams. We theorize that while the common fate of members of egalitarian teams makes them likely to unite and pool resources when facing an interteam conflict, the power differences in hierarchical teams cause members to be differently impacted by the resource-threatening interteam conflict, leading them to have different perspectives and concerns, thereby promoting internal fights over resources (i.e., power struggles). In turn, such power struggles are
expected to negatively affect team performance. We tested these hypotheses with a laboratory study of 85 three-person negotiation teams and a field study of 158 organizational work teams, and found, as expected, that a resource-threatening interteam conflict promotes performance-detracting power struggles in hierarchical (but not egalitarian) teams.
