Directive 2009/52/EC of the European Parliament and of the Council of 18 June 2009 providing for minimum standards on sanctions and measures against employers of illegally staying third-country nationals
This Directive establishes that cooperation among Member States should be strengthened to tackle illegal immigration. In particular measures against illegal employment should be intensified at Member State and EU level.
Member States should guarantee the full effectiveness of the general prohibition by providing criminal penalties in their national legislation in serious cases, such as the illegal employment of a significant number of third-country nationals, particularly exploitative working conditions, the employer knowing that the worker is a victim of trafficking in human beings and the illegal employment of a minor.
The Directive stresses also that Member States should be free to grant residence permits of limited duration, to third-country nationals who have been subjected to particularly exploitative working conditions or who were illegally employed minors and who cooperate in criminal proceedings against the employer.
