We examine the impact of subjective power on leadership behavior and demonstrate that the psychological effect of power on leaders spills over to impact team effectiveness. Specifically, drawing from the approach/inhibition theory of power, power-devaluation theory, and organizational research on the antecedents of employee voice, we argue that a leader’s experience of heightened power produces verbal dominance, which reduces perceptions of leader openness and team open communication. Consequently, there is a negative effect of leader power on team performance. Three studies find consistent support for this argument. The implications for theory and practice are discussed.
