Sociological research shows that Germany has for years been the preferred destination of Polish gainful migration which adopts a variety of forms. The present study analyzes a wide range of issues connected with the three most frequent manifestations of work activity of Poles in Germany today: seasonal work, work contracted with the German employer and jobs contracted with Polish companies that offer services in Germany. Analysis of migration streams revealed a large scale protection of the German job market. The situation did not change after Poland's accession to the European Union as the FRG and Austria availed themselves of the possibility to introduce a maximum transition period. This policy was adopted in spite of reports by analysts of the German job market who had for some years drawn attention to the enormous problems this country's economy would face due to an insufficient number of qualified work force.
