A US consumer body has launched a Facebook campaign aimed at enhancing the safety of textile workers in Bangladesh after last month's deadlyfactory collapse that killed over 1,100 people.National Consumers League (NCL), a consumer and worker advocacy group, said that it is launching the social media campaign that enables consumers to inform retailers that theywould be willing to pay 10 cents more for every garment purchased which will go towards improving worker safety in Bangladesh.The NCL says, its '10 cent' campaign is based on scientific calculations.According to a Worker Rights Consortium calculation,rebuilding Bangladesh's unsafe factories and installing appropriate safety equipment would cost 3 billion US dollars, or a 600 million US dollar investment every year for five years.Bangladesh is the world's second-largest apparel exporter of western brands.
