Arbitration means the two sides (or parties to the dispute) agree to use a third party to settle a dispute. A third party is someone who is not from the union or employer’s side. The arbitrator acts as judge to decide the dispute. Under the LRA, the arbitrator is a commissioner from the CCMA or Bargaining Council. After hearing what both parties have to say, the commissioner can make a ruling that is legally binding and must be accepted by both parties.
