Survey data indicated that being of childbearing age, having children, and holding positive attitudes toward women were positively related to perceptions of parental-leave policy fairness. These findings supported the proposition from social justice theories that relation (similarity) to the object of resource distribution influences perceptions of fairness. The study also replicated the egocentric bias effect such that planning to bear children and expressing intent to take leave were positively related to perceptions of policy fairness. Policy-fairness perceptions were related to attitudes toward parental leave recipients (leave takers), and the data supported a mediation model in which fairness perceptions mediated the relation between similarity to, and attitudes toward, leave takers. The theoretical implications for theories of social justice and the practical implications for parental leave are discussed.
