The research carried out by the EU Fundamental Rights Agency explores criminal exploitation of migrant workers moving within or into the European Union.
According to Migrant Right Centre Ireland, which has seen the report, domestic workers topped the list for exploitation here, followed by workers in the accommodation and food service sector and those in agriculture, forestry, and fishing.
Pablo Rojas Coppari of the Migrant Rights Centre Ireland said: “These report findings tally with what we have seen in the past 14 years of working with migrants in Ireland.
“By the very nature of the job, domestic workers are isolated, and often unaware of their rights as workers. In addition, the vast majority are women, and many are undocumented; they are afraid to leave and afraid to go to the authorities.
Jane Xavier, a former au pair turned rights activist, said it was particularly appalling that people caring for children are at such risk of exploitation.
