The paper describes migration from Poland, its impact on the country labour supply and on the social security system in the sending country. It shows both advantages and disadvantages of migration. On one hand, there are remittances as a source of income for households and possibility to work abroad when unemployment in the source country is high. On the other hand, in the long run migration can possibly accelerate unfavourable ageing of workforce. Additionally, the authoress draws attention to still very low labour force participation rate of people over 55 in Poland (in comparison to other EU countries).
