Since the early 1980s a number of institutions in South Africa have championed mediation. The Independent Mediation Service of South Africa (IMSSA) was established in 1984. It trained mediators who then worked through Local Dispute Resolution Committees set up as part of the National Peace Accord. Initial training was undertaken by the UK's ACAS. IMSSA covers mediation within unionised environments. The more recently created Commission for Conciliation, Mediation and Arbitration (CCMA) was formed as result of the Labour Relation Act No 66 1995, and replaced the Industrial Courts in handling large areas of employment disputes.
