Migrants in Poland have the second least favourable eligibility for the labour market after FR. No matter how long they have worked in Poland, they do not have equal access as EU nationals to self-employment or employment in most sectors. They also face more restrictions than EU nationals to set up a business. Most work permits are renewable, but migrants are only halfway secure since they lose their permit if they lose their job, no matter how many years they have worked in Poland. Labour market integration measures to help migrants find jobs are critically weak in Poland, as in AT, CZ, and MT (see box). Migrant workers have the right to join trade unions, but they cannot change their job, employer or profession without applying for a new permit.
