Workers at the Tuba Group factories are understood to have set a 25 September deadline for the Bangladesh government to pay them compensation or face demonstrations before the Eid festival on 4 October.

According to the Dhaka Tribune, workers are also demanding that the group's five closed factories are reopened.

The factories suspended production last month after around 1,600 workers went on strike over unpaid salaries and bonuses.

Tuba Group boss Delwar Hossain was jailed in February for his role in the Tazreen Fashion factory fire, which killed 112 workers in November 2012. His imprisonment was blamed for the failure to pay workers.

He is now seeking a BDT300m (US$3.9m) government loan to reopen the apparel factories.

Workers have now submitted a memorandum mentioning their demands to State Minister of Labour, Mujibul Haque Chunnu, the Dhaka Tribune noted.

Addressing a rally earlier this week, the committee's convener Moshrefa Mishu said workers of the five factories were living their lives in "inhuman conditions" as they were unable to pay their house rent or buy necessary food and daily necessities. They were constantly being threatened by their creditors.

The State Minister for Labour, however, told the publication that existing laws do not allow "prompt punitive actions" against the factory owners, including ready-made garment industries. By following the existing labour law, it takes "a long time to protect the workers' interests" by filing cases against the owners, he said.
