Retailers deal with supply-chain workers' safety

Much of the world's clothing is made in Bangladesh factories, some unknown number possibly as dangerous as the factory where last month, more than 1,100 workers tragically lost their lives in a building collapse.

Now H&M, Zara, Benetton and several other big-name retailers have committed to working closely with factory owners and the government to improve conditions. H&M issued a statement saying it wants to create an environment 'in which no worker needs to fear fires, building collapses or other accidents that could be prevented with reasonable health and safety measures'.

UK's Primark and Canada's Loblaw will compensate the family of victims of the factory collapse. According to a Loblaw statement, 'We are working to ensure that we will deliver support in the best and most meaningful way possible, and with the goal of ensuring that victims and their families receive benefits now and in the future'.

Walmart has so far decided to conduct safety inspections on its own, saying it believes this is the fastest way to uncover and correct potential problems. The world's largest retailer plans to post the results of its factory inspections on its website, because 'transparency is the ultimate accountability mechanism'.
