Building on Foa and Foa's (1974) resource theory, this study explores why, how, and when followers’ proactive engagement in taking charge behaviours can drive leader–member exchange (LMX) relationships. Through a three‐wave multi‐rater field survey among 230 leader–follower dyads in China, we found that follower taking charge is positively related to LMX after accounting for the effect of in‐role performance. Our results suggest leader perceived service resources (i.e., the efforts and actions carried out by the focal follower that make the leader's work more effective) as the underlying mechanism of this relationship. Further, our findings demonstrate that achievement‐goal‐striving leaders are more likely to recognize the service value of taking charge followers and subsequently develop high‐quality LMX relationships with them. This study moves LMX theory forward by investigating follower‐driven LMX development. It also contributes to the emerging work on followership by ‘reversing the lens’ between leadership practice (in terms of LMX) and follower behaviour (in terms of taking charge).
