Where there are pre-mediation meetings, they are generally one-on-one meetings where the Mediator meets separately with each party to explain the process, get an overview of the situation and ascertain the ability and willingness of each party to engage in a mediated intervention. If the parties are to be represented during the mediation, the Mediator may meet those parties who will attend in a support capacity at this stage, e.g. union representatives, lawyers, supporters. Where all parties have agreed to engage, a written Agreement to Mediate will be discussed and agreed between the parties and the Mediator and it will set out amongst other things that the mediation is confidential, that it is a voluntary process and that any party or the Mediator may leave the process at any time. Sometimes the Agreement to Mediate is agreed and signed before the day of the mediation and on other occasions it will be signed at the start of the mediation. Except where a third party is paying the fees of the mediation, the Mediator and the parties should agree the fees before the start of the mediation. While the parties control the content of the mediation, the Mediator is responsible for the process and during the course of the mediation will work with the parties - sometimes in joint and sometimes in separate sessions. The mediation process improves communication, narrows outstanding issues and defines areas of agreement, leading to successful resolution in about 80% of cases. Where full agreement is not reached, generally parts of the dispute are resolved, leaving fewer or less extreme differences to be resolved.
