Eastern Europe, in this case. Bangladeshi workers might be heading for Poland. In England and indeed throughout the UK we have experienced a rush of workers from Eastern Europe. Lithuanians, Latvians, Romanians, Poles etc. They are employed in various capacities from restaurant staff to construction industry work to farm labour.  As people leave for Western Europe, they have contributed to a shortage of labour. And this is where the Bangladeshi workers might potentially fit in. This is the pecking order for edging westwards!
The cheap polish builder has become a bit of a caricature in the UK. I wonder what the Bangladeshis will face in Poland….hmm.
