The World Bank in its document under the title'Investing in Health'(1993) states that the health status of the population, including the working population, and working conditions in individual countries depend essentially on the value of gross national product per capita. The attitudes towards the role and objectives of occupational medicine have changed significantly over the last three decades. A high priority given to primary prevention reflects the mainstream of a new approach to preventive measures. Advancements in technology, production and services, common use of computers and flattening of work organisation structures have brought about the need for workers' active participation in planning of activities and shaping working conditions in own enterprise. At the same time, workers are required to possess much higher qualifications facilitating their participation in applying new technologies and using new information systems, which resulted in a fierce competition on the labour market. In the countries in the political, social and economic transition, the conditions for introducing a new system of sustained development, described by Gustavsen at the 25th International Congress on Occupational Health have not as yet been established. A procedure-based system involving negotiations between employers and workers' representatives failed to be successful in improving working conditions as the roles of the state, employers and trade unions had not been defined precisely. It is expected that further health promotion at the worksites in these countries will depend mainly on the economic progress and the reformed system of education.
