In the previous article from a series dedicated to employing foreigners in Poland. we discussed hiring third-country nationals. We have explained that this involves a range of obligations both for the employer and the employee, and any failure to meet these obligations results in certain penalties. Today we are going to analyse whether hiring a foreigner who is a citizen of the European Union (EU), European Economic Area (EEA) or Switzerland (hereinafter referred to as an EU citizen) is indeed a less complicated procedure. Does the employer face penalties if he or she fails to observe the procedures related to a foreigner’s stay on the territory of Poland?
