The article aimed to analyse the labour market in Poland in relation to the employment of foreigners, especially immigrants from Ukraine, showing not only the dimensions of economic immigration over the period 2009-2019 but also the impact on the Polish economy. An analysis of the changes in the situation of foreign workers in the labour market over the last decade shows that despite an increase in employment among foreigners, they are not competition for native employees, which means that they “do not take jobs”, on the contrary – they fill the gap where there is a shortage of native employees, because, for example, they went abroad or do not want to take niche, low-paid jobs.
