Workers incensed by rumors of a co-worker’s death in a police firing burned down one of Bangladesh’s 10 biggest garment factories supplying to major Western brands on Nov. 29:
According to authorities, factory workers were enraged after a loudspeaker from a mosque announced a worker’s death during a police firing to disperse a road blockade by factory employees earlier that day.
Six months’ worth of supplies for U.S. brands, including Gap and Wal-Mart, were burnt in the fire. Other burnt garments included those from huge global brands such as American Eagle Outfitters, Marks and Spencer, Sears, Uniqlo, and Zara. A Standard Group official estimated that the firm could lose well over $100 million in the fire.
