Bangladesh labor activists and manufacturers Wednesday welcomed plans by foreign retailers to improve shocking safety standards at garment factories after a disaster which killed over 1,100 workers. The retailers' promise followed last month's collapse of a nine-story factory complex outside Dhaka that killed 1,127 people in one of the world's worst industrial disasters. Labour activists have campaigned for years for a Western retailer-led drive to improve factories where workers toil long hours in sweatshop conditions for paltry pay. The retailers' commitment represents a "huge victory", said Kalpona Akter, head of the Bangladesh Centre for Workers Solidarity. The agreement, backed by a Europe-based labor coalition called IndustriALL, is "going to benefit each and every garment worker", he said. Top global brands including Benetton, Carrefour and Marks & Spencer joined clothing giants Inditex of Spain and H&M of Sweden on Tuesday in signing on for the deal to improve fire and building safety to avert future tragedies. Italy's Benetton, along with Spanish company Mango and British retailer Primark, had placed orders with plants based in the Rana Plaza complex which after the cave-in was found to have seriously violated construction laws. "We welcome this agreement," said Atiqul Islam, president of the Bangladesh Garment Manufacturers and Exporters Association which represents 4,500 apparel factories.
