There is still "room for improvement" in the protection of workers' rights in factories making shoes and clothing for Adidas-Salomon, Eddie Bauer, Levi Strauss & Co, Liz Claiborne Inc, Nike, Phillips-Van Heusen and Reebok International an industry-backed group said on Wednesday. Announcing the results of independent and systematic audits of 50 overseas factories, the New York-based Fair Labor Association said firms violated labour laws ranging from inadequate pay to failure to provide proper hearing protection, paid workers less than the minimum wage and failed to register workers ages 16 to 18.
