A mediator working for organisations

In a disagreement, how do you encourage the protagonists to change from a defensive strategy to one where everybody wins, while still giving them freedom that will guarantee their support for the process and ensure success in the end ? Gilles Barouch outlines his techniques of mediation which he developed during his projects in different public services. He illustrates his methods with the story of his part in a conflict between pig farmers and ecologists in the Tarn region.
