Human resources - that is, the set of knowledge, skills, abilities, experience and creativity of employees - is one of the most important resources of the modern economy. The knowledge, ability and innovation of workers influence the growth of productivity, which directly contributes to increasing the competitiveness of companies and the economic growth of the country. In modern economies, material resources (such as land, capital or technology) are no longer crucial - it is the human factor that enables these resources to be used optimally. At the micro level, human resources are key to a company's competitive advantage, while at the macro level, it is the basis of national competitiveness and sustainable development.
