Work ethic is a general concept, which starts from the idea that hard work and professional diligence are a source of moral reward and have the intrinsic capacity to form characters and to strengthen personal abilities. Its moral principles, used systematically, can induce desirable behavior and mental attitudes that result in high-quality work. Constantly fueling personal needs and goals, such an attitude is capable of increasing individual self-esteem and represents a source of satisfaction and professional fulfillment. In the medical field, the implementation of these principles is a necessity, deriving from the both elitist and apostolic character of the medical professions. However, these liberal professions are governed by the principle of professional independence, so it is not possible to mechanically apply the general rules of work ethic. Starting from the characteristics of the concept (professionalism, high productivity, teamwork and cooperation, determination to succeed, high-quality work), the paper analyzes the particular way in which these apply to the medical field. In this context, topics such as: individualized approach to the patient, planning of working time, the need for continuous self-improvement, development of transversal competences (including the relationship with colleagues), the impact of medical professions on the community and society (the concept of social responsibility) etc. are being considered. Last but not least, the paper recalls that professional independence corresponds to a particular type of responsibility. The deontological rules specific to medical professions are found in self-regulatory codes, the breach of which implies specific sanctions in the field of disciplinary liability.
