Despite the technological development, maritime transports still depend on human action. Cargo and passenger ships are under crew responsibility and this entails the need to have on board a qualified staff. International and European institutions periodically record a high level of withdrawals from the maritime profession, often at the beginning of the career. One of the main reason for withdrawing, following opinions and essays of international rulers, trade unions and shipowners, is stress. Hard workshifts, few sleeping time, being far from home for long periods, difficulty in communicating with colleagues, nostalgia, the sense of isolation, are all considered “stressors”, factors which can cause distractions and, at the extreme consequences, actual pathologies. People know that, and increasingly decide not to undertake the maritime profession, this way impoverishing the whole maritime cluster of excellent human resources.But the issue doesn’t have only consequences on workers’ health and well being, neither only on the number of qualified staff working on merchant ships. Stress has also consequences on the perspective of costs. Costs for public health, enterprises, environment and other sectors related to maritime transports. These reasons are on the basis of international rulers attention, who are working to put stress as key-issue in the major conventions, either to ensure a safer navigation and more well being for workers, and to advise maritime education and training (MET) institutions about the need for new approaches on that subject. METs are increasingly requested to provide maritime students, since secondary school, with the tools to recognize “stressors”, anticipate malaises, and manage the consequent symptoms in themselves and in the others. Such kind of new tools is expected to contribute in creating a better work context, more well being for workers in living their worklife, more effectiveness, productivity and safety.
