Scores of garment factories in Bangladesh have shut down as workers went on strike. This could in a way hit supplies to top Western retailers during the busy holiday season.

The Bangladesh Garment Manufacturers and Exporters Association (BGMEA) closed 55 factories in a suburb on the outskirts of Dhaka, association president Siddikur Rahman said, after police arrested at least seven people who were leading the strike. These factories will remain closed until the government says it is safe to reopen them, Rahman added.

Here, it must be noted that workers there went on strike nine days ago in protest against the firing of 121 of their colleagues and soon added a pay hike to their list of demands. The protest escalated earlier this week when police fired rubber pellets, injuring 10 demonstrators according to labour leader Taslima Akhter.

Several hundred policemen have since been deployed in the industrial zone, home to the factories which supply leading Western retailers such as GAP, Zara and H&M. The workers want their salaries to be tripled from 5,300 taka (USD 67) to 16,000 taka.

The government raised the minimum wage for garment workers to 5,300 taka in 2013 after the industry came under intense international scrutiny over a series of disasters that killed scores. But even after the increase, Bangladeshi garment workers remain among the lowest paid in the textile sector in the world.

Bangladesh's USD 30 billion garment industry has a woeful history of poor pay and conditions for its four million workers. The garment workers have vowed to continue the strike until their demands are met. Garment manufacturing makes up for 80 per cent of Bangladesh's exports and a prolonged interruption would have a cascading impact on the impoverished country's economy.
