The aim of this study was twofold: to analyze the possible relationships between employees’ personality (as measured by core self-evaluations or CSE) and their feelings of work-family enrichment (WFE); and to examine whether distributivejustice perceptions act as a mediator in such relationships. A cross-sectional survey was conducted to collect data from 386 employees in public and private organizations located in Argentina. Structural equation modelling wasused to examine two integrative models that combined CSE, distributive justice, and WFE. Results reveal a good fit of the full mediation model (S-Bχ2 = 3.18, GFI= .99, CFI= .99, RMSEA= .03), in which distributive justice perceptions fully mediated the relations between CSE and WFE (γ = .13, IC= [-.03; .27]) and between CSE and FEW (γ = .09, IC= [-.08; .25]). Findings are discussed in the light of its theoretical and practical implications. The study provides valuable information for organizational authorities and HR managers to focus their efforts on both the development of CSE traits and the creation of fair and equitable work environments.
