Within the Polish labor market, immigration—along with flexibility, globalization, and mobility—has increased in importance. Because of the many cultural and historical similarities to Poland, as well as geographical proximity, Ukrainians play a very important role. They mostly take on the unattractive (from the point of view of the local worker) work-world positions: ones that are low paying, temporary, and offer insecure and uncertain lengths of employment. Using two in-depth case studies on Ukrainian migrant workers employed in diverse Polish industries, we answer the question of whether Ukrainian citizens working in Poland (economic migrants) are precarious workers in light of Vosko’s and Duell’s concepts of precariat.
