One of two unions at steelmaker POSCO agreed to withdraw from the Korean Metal Workers' Union (KMWU) under the Korean Confederation of Trade Unions (KCTU) in a vote held from Monday to Wednesday. After ballot counting started at 5 p.m., Wednesday, the union announced its withdrawal plan won the support of 69.9 percent of its members with a voter turnout of 58 percent. If the plan wins the support of more than two-thirds of members with a voter turnout of at least 50 percent, the steelmaker's union can leave the militant umbrella union.
