Working life is along with being a part of one's routine life, especially in the societies like us it is the great part of a person and because of this it shows the qualifications which effects and identifies the person in a large scale. Thus, person can easily and automatically makes the working life a part of his private life. At this point, some problems which the person cannot identify and cannot cope with can arouse. In the context of whether the person's special affairs or the habits and the attitude of the society in the working life, some problems which are not in the inner dynamics of the working life but can be come across so often draw one's attention. As these kind of problems called "mobbing" can be mixed up with other behaviours, a seperate field of study and discussion is delayed by a historical aspect, but from now on it manages to enter into the subjects of psychology of working and organizational sociology.
