The aim of the project is to map processes of marginalization in the labour market as one of the main factors of social exclusion. It is especially about defining key positions in the labour market that traditionally have a more or less supplementary role – in comparison with the perceived risk of unemployment. These are various forms of flexible jobs. We will check to what extent the changes in global production and financial processes reflect, together with policies, in the position of these people. The project will be based on two to three case studies (analysis of wholesale statistic data – in statistic as well as dynamic level, interviews with type-chosen people in endangered situations). Quantitative findings will be confronted with European Community Household Panel (ECHP) on the level of social state mode, which was carried out in 1994–2001, and which will enable observation of influences of social state institutional conditions on formation of a flexible work force. Qualitative studies will extend the descriptive level of an attempt to explain the way and formation processes.
