The article deals with the results of the analysis of the person’s professional mobility as a comprehensive tool for overcoming the professional crises. It also determines the existence of many unascertained psychological problems in its structure. One of these problems is the problem of overcoming maladaptive forms of a person’s psychological defence based on his professional mobility in stressful conditions of the professional development crises. Stressful uncertainty in the professional crisis and the high ambivalent tension, which the person is experiencing, characterize the specialist’s maladaptive development according to the “catastrophic” scenario. In the conditions of the professional development crisis a specialist cannot leave it adaptively and flexibly due to a limited number of rigidly patterned professional barriers and behaviour models. Such maladaptive patterned movement of a specialist towards the disintegrational destruction of the whole system of his professional development can be overcome constructively on the basis of his professional mobility model, selection and realization of the further professional movement vector. We consider the interactive strategy of a specialist’s behaviour for constructive overcoming professional crises in the system of his professional development, based on the development of the ability of directed transitions to new professional movement trajectories in the points of the system bifurcation, as the professional mobility.
