DETROIT (AP) — Members of the United Auto Workers union have overwhelmingly approved picking their leaders by direct ballot elections. In doing so they have rejected a system that many blamed for corruption in the union’s top ranks. The so-called “one member, one vote” measure got nearly 64% of 140,586 valid ballots that were received by Monday’s mail-in deadline. About 36% favored the current system of leadership picked by delegates to a convention. That’s according to results released Thursday. The results are not official until approved by the Labor Department and a federal judge. The election of the union’s 13-member International Executive Board is likely to take place next summer or fall.
