China’s official union is leading protests outside a Wal-Mart (WMT.NYSE) store in Changde, Hunan province, which closed last week, Financial Times reported. A unit of the government-sanctioned All China Federation of Trade Unions is involved in the protest over compensation for workers who lose their jobs and subsidies for those who transfer to stores in other cities. The ACFTU’s involvement in an industrial action is extremely rare. Two other protests have erupted at stores closing this month. Walmart said it was closing about 20 stores as part of a wider restructuring of its China business.
