The innovative potential of EU countries is mainly influenced by expanding automation, robotization and digitization, as well as demographic developments and advancing globalization. These trends bring with it a complex and structured system of changes associated with several human activities, including the labour market. Transmission of the so-called tacit knowledge is becoming a key area as well as the follow-up ability to cooperate between individuals. Because of ageing population in selected countries, for instance in the Czech Republic, Italy, Slovakia and Germany, cross-generational cooperation can seem like an essential new skill in the contemporary world. It is important to say that the issue of population ageing is a crucial problem throughout the EU. Over past 10 years, the European Union Member States have seen an increase of Old Age dependency ratio (% of the population aged 65 years or more relative to the population aged 15-64 years) by an average of more than 4 pp. (EUROSTAT, 2020). For instance, according to the data from Eurostat, the figure was 25 % in 2005 and 29 % in 2015. For this reason, the aim of the analysis is to demonstrate the importance of cross-generational cooperation as a present and future ability of individuals in the labour market and to find out how their networks could be developed.
