The potential for conflict is inherent in the employment relationship with consequences for social relations and business performance. Countries evolve their own processes and systems of conflict resolution, adapting to variations in context. Scant research has been conducted comparing cross-national processes and systems, a notable exception being Behrens et al. (2017). The research project outlined here begins to fill that gap by comparing public mediation provisions across Ireland and New Zealand charting evolution, contextual influences, use, outcomes and effectiveness. The purpose of the project is to inform policy and practice, the academy, and to inform other international comparisons.
