Bangladesh announced a six-member wage board on Sunday to review garment workers' pay and urged employees to return to work, but ​protests demanding higher wages continued across major industrial areas, disrupting transport ‌and factory operations. Workers in the South Asian nation are demanding a minimum monthly wage of 30,000 taka ($245), more than double the current 12,500 taka, saying rising costs of food, housing, transport and ​healthcare have sharply eroded their purchasing power. The dispute has raised concerns about ​disruption to an industry that employs about 4 million workers, generates more ⁠than 80% of Bangladesh's export earnings and supplies clothing to many leading Western ​brands. Labour and Employment Minister Ariful Haque Chowdhury said the wage board was formed after ​discussions with workers' representatives and industry leaders and urged workers to resume work. Despite the announcement, thousands of garment workers staged fresh demonstrations on Sunday.

Some protesters hurled ​bricks at officers during the clashes. Hundreds of workers also blocked a major highway in Gazipur, on ‌the ⁠outskirts of the capital, disrupting transport in one of the country's key industrial belts. The demonstrations forced owners to shut 25 to 30 factories, while authorities deployed Border Guard Bangladesh personnel to maintain order, Gazipur Industrial Police Superintendent Mohammad Amjad Hossain said.

Chowdhury warned that prolonged disruptions could delay export shipments ​and payments ⁠from international buyers, creating further difficulties for manufacturers and workers alike. Bangladesh's ready-made garment industry, the world's largest after China, contributes about 10% of gross domestic product and is the ⁠backbone of ​the economy. Manufacturers, however, said the sector is facing mounting challenges, including rising production costs, periodic gas and electricity shortages, and uncertainty in energy markets linked to tensions ​in the Middle East.
