How to Handle a Selfish Teammate Without Creating More Conflict

A selfish team member is a common yet tricky issue that every leader faces. When a colleague hoards resources, withholds vital information, and prioritizes personal success over collective progress, it can undermine trust, morale, and ultimately, productivity. How should you respond to such behavior and turn things around? In today’s episode, we explore the roots of selfishness in teams, tracing it back to evolutionary psychology, where human survival depended on both cooperation and hoarding resources. We unpack the psychological and social factors that drive selfish behavior today and explore tips for turning a selfish team member into a collaborative one. As a leader, your actions set the tone for the entire team. You must address both the selfish behavior and the culture it creates to foster a climate of collaboration and trust in your organization.In this episode:- Evolutionary roots of selfishness in teams- The role of psychological safety in collaboration- Practical strategies to combat selfishness- Key takeaways and call to actionResources Used in the Episode:Boehm, C.
