BEIJING (AP) — Chinese police hauled away dozens of workers Friday to break up a march on a factory complex targeted by tens of thousands of laborers striking against the world's largest maker of athletic shoes, while a government trade union said it would mediate the labor dispute. Management of Yue Yuen could not immediately be reached for comment, but in a public announcement Thursday, the company offered to make social security payments only if the workers would agree to retroactively pay their own required contributions into the fund. Advocates for the workers said the company had deceived its workers and violated the rules by failing to pay into the country's social security program and should be held accountable for the missed contributions. Companies in the Pearl River Delta routinely skip social security payments with tacit approval by the local government, which wants to see the plants stay local instead of moving overseas, Zhang said.
