Disentangling the relational approach to organizational justice: Meta-analytic and field tests of distinct roles of social exchange and social identity.

Social exchange- and social identity-based mechanisms have been commonly juxtaposed as two pivotal proxies of the relational approach for studying organizational justice. Despite their distinct theoretical roots, less is known about whether and how these two proximal mechanisms complement one another in accounting for justice effects on key outcomes. Tracing back to their disparate fundamental premises-"reciprocity" underpinning social exchanges and "oneness" underpinning identity construction-we attempt to disentangle the relative mediating effects of these two mechanisms. Our empirical testing hinges on one meta-analytic study with 105 independent samples (
