In the last week of October, a supplier for Wal-Mart Stores Inc. placed an order with garment-maker Simco Bangladesh...Simco subcontracted the work to another company without Wal-Mart's authorization, [a] Simco executive said. Wal-Mart, which said it has strict rules for factories manufacturing its orders, declined to respond to specific queries about the shorts order. When the subcontractor's factory [Tazreen Fashions (part of Tuba Group)]...burned down...killing 112 workers, it exposed the lines that some Bangladeshi manufacturers...cross to get the work done...Wal-Mart declined to comment on the details of the audits of any Tuba Group companies. It said that its supplier...had sourced garments from Tazreen Fashions without authorization and that it had terminated its relationship with the supplier after the fire.
