A protocol has been signed between the three organisations which will see them work together to support Polish migrants and ensure their rights are protected.
Brendan Barber, the general secretary of the TUC, said Polish workers play a "vital" role within the UK economy and make a valuable contribution to the country’s diversity.
"Sadly, many Polish workers who come to the UK without enough knowledge of employment law or a trade union to support them can find themselves ruthlessly exploited by employers."
He said the three unions will work with Polish migrants in the UK to help them understand their rights and make sure they earn a fair wage.
From November this year, employers wishing to recruit migrant workers from outside the European Economic Area will have to apply for a sponsorship licence.
