Poland has had the highest incidence of temporary employment among the EU countries since 2009. However, due to a lack of proper data, only a few empirical studies have been devoted to analyse the consequences of temporary employment for future career and economic prospects on the Polish labour market. In this study the data from the Social Diagnosis panel study for the years 2009–2013 are used in order to analyse these consequences. The results reveal that although the chances for the temporary employed of finding a permanent job increase and the risk of being unemployed decreases over time, the negative consequences of temporary employment for income and its perceived stability do not seem to diminish.
