Abstract. Ukrainian citizens constitute an absolute majority among all categories of foreigners working in Poland. Their employment is largely characterized by over-representation in jobs with poor working and hyper-intensive conditions; by  concentration in certain sectors of  the economy; by a mismatch between work performed and available qualifications; and by weak legal protection. Limited access to stable employment, work in the «shadow economy», failure of employers to meet their financial obligations, and legal insecurity discriminate labor immigrants. The integration policy consists mainly of scattered events and does not form a coherent, long-term national strategy. While NGOs in several Polish voivodships and individual employers may tackle the issue of migrant integration, only a small proportion of legally employed Ukrainians are covered by integration measures. Short-term migrants and those employed in the “grey zone” are virtually “invisible” to both Polish society and the authorities.
