In the weeks following the horrific Rana Plaza building collapse that killed 1,127 workers — one of the worst tragedies in the history of the garment industry — more than 30 of the world’s leading apparel companies signed an agreement vowing to protect the safety of garment workers. But two prominent American companies have refused to sign the accord. Wal-Mart announced plans to launch its own safety initiative, and Gap has refused to sign any agreement, citing liability concerns. In a recent LA Times op-ed, law professors James Brudney and Catherine Fisk call the companies’ fears over their financial and moral commitments “irrational.”
