Details continue to emerge on the retail giant Wal-Mart’s ties to the Bangladeshi garment factory where 120 workers died in a fire last month. The New York Times has revealed that at least two subcontractors were using the Tazreen factory to make Wal-Mart goods when the fire occurred. Wal-Mart has claimed it cut ties to a lone company that had used the factory before the fire. But documents recovered in the fire’s remains show the factory had billed one of the two Wal-Mart subcontractors on November 24, the very day of the fire. Previously recovered documents have shown that five of the factory’s 14 production lines were devoted to making Wal-Mart apparel. Two people involved in worker safety oversight in Bangladesh have also revealed that Wal-Mart played a key role in blocking the improvement of electrical and fire safety at Bangladeshi factories during a 2011 meeting.
