A group of Apple customers will show up at Apple's headquarters and stores in D.C., New York, San Francisco, London, Sydney, and Bangalore on Feb 9. They will be delivering petitions signed by 250,000 people asking the company to develop a worker protection strategy in response to reported abuse in Chinese supplier factories, Business Insider reports.

The renewed interest in Apple's worker policies sprang from an episode of Public Radio International's "This American Life" that aired last month. It was a special report on worker conditions at Apple's manufacturing facilities and workers' conditions. It showed how iPhones are built in part by adolescents working 16 hours a day for 70 cents an hour.

Apple CEO Tim Cook has since responded to the uproar, saying in a recent interview, "We care about every worker in our worldwide supply chain." Cook also said that Apple now has the Fair Labor Association monitoring its suppliers.

According to the report, activists will try to prove their point by wearing iPhone costumes, waving iPhone posters and delivering petitions in Mac boxes.
