One of the most effective management systems is the so-called lean management (LM) aimed at loss minimization of institutions' activities while maximizing value and satisfaction to the clients. The system implementation comprises not only typical business areas but also health care sectors. The aim of the article is to present the concept and opportunity of improving the management of occupational health units. Due to its multi-profile nature of tasks and diverse relations with the environment occupational health could be a good institutional example of LM implementation. Operational perspective consists of five guidelines: describing values expected by final clients, setting value flow eliminating needless elements, creating the integrated, coherent and smooth sequence of valuable activities, offering the values to clients, and aiming at continuing improvement. LM could be implemented in occupational health units in the following areas: timing and tasks coordination, leaning some tasks and expanding others in order to maximize clients' value, cost rationalizing, improving the quality of services by eliminating mistakes, avoiding repetition of activities.
