Dock workers at Chittagong Seaport announced a non-stop siege programme from Tuesday to realise their four-point demand, in what looks like a return of the trade-union troubles of the yesteryear, the Bangladesh Financial Express reported.

Jahangir Alam Chowdhury, convener of Chittagong Port Dock Workers Unity Council, announced their decision on the tough action like laying siege to the country's main seaport from a rally at the city's Nimtali crossing in the evening.

Several hundred workers demonstrated around the port this evening to drum up their agitation plan.

Meanwhile, Dock Workers-Employees Federation will hold a rally in front of Newmooring Container gate on the same demands.

Late last week, the port workers threatened to bring the port activities to a grinding halt from January 12 if their four-point demand was not met by January 11 deadline.
