Yesterday, on my flight to Singapore i found two skilled insulation works technicians aka migrants workers from Kolkata speaking in thick Bardhaman dialect of Bangla which is very familiar as a part of my family comes from Birbhum/Asansol belt. They are a part of a rising trend from mofussil Bengal from Hindu agrarian families to take up work in Singapore, in parallel to their cousins from across the border.
Malda and Mushirdabad has long held diaspora networks in the Gulf.
It is interesting to note these transnational migrant worker networks which are taking root in West Bengal. Bengali diaspora is more than the standard categories of the East Coast Presidency College Grad Student and the West Coast Jadavpur IT grad.
