This implies the need for research in all dimen-sions of his work. Much has been said about the mediation procedure, about the ways of conducting it, about ethics and even the desired qualities of a mediator, but it has not yet been examined whether his/her work is safe, and if not, what constitutes the greatest threat in it.
