The Wall Street Journal reports that Wal-Mart has been warning its managers that an Obama victory in the fall would lead to unionization at Wal-Mart stores. In recent weeks, thousands of Wal-Mart store managers and department heads have been summoned to mandatory meetings discussing the downsides of unionization. The Journal reports the Wal-Mart human resources managers who run the meetings don’t specifically tell attendees how to vote in November’s election but make it clear that voting for Obama would be tantamount to inviting unions in.
