Abstract: | Based on data collected from 205 vertical dyads, we found that subordinate–supervisor similarity in their self‐reported growth‐need strength (GNS) had a positive effect on subordinate‐perceived and supervisor‐perceived global similarity. The findings also suggested that subordinate‐perceived global similarity mediates the link between similarity in GNS and subordinate's trust in and loyalty to supervisor; whereas supervisor‐perceived global similarity mediates the link between similarity in GNS and supervisor‐rated in‐role/extra‐role performances. In addition, we found that subordinate–supervisor similarity in self‐reported GNS and perceived global similarity had independent effects on work outcomes for both subordinates and supervisors.
