Effects of procedural fairness and leader support on interpersonal relationships among group members

In this article, the authors examine the impact of fair treatment by a group leader on people's relationships with and feelings toward other individual group members. Previous studies neglected procedural fairness effects on interpersonal relationships between group members. The authors hypothesized that fairness affects interpersonal relationships and feelings toward another group member only when the leader is regarded as representative and supported by the other group members. In three studies, the authors manipulated procedural fairness (no voice vs. voice) and other group member's support for the leader (full vs. mixed support for the leader). Two vignette studies supported the hypothesis. In addition, an experimental laboratory study showed that this interaction effect between procedural fairness and leader support was most pronounced among those with high belongingness needs.
