In my last post, I identified some unions and employers that have been enjoying a successful year in the organizing arena, based on the just-released NLRB Election Statistics Mid-Year 2012 Report. But, for every winner, there is a loser. Here is a list of parties that have not fared as well.

• Independent unions. When it comes to win percentage, labor organizations not affiliated with either the AFL-CIO or Change to Win consistently outperform the two large federations. That might not happen this year, however. Independent unions won just 62 percent of their NLRB elections in the first half of the year, down from 72 percent during the first half of 2011 and close to the 60 percent win rates posted by both federations.

• Retailers and wholesalers. Employers in the retail and wholesale trade industries saw unions in their workplace win twice as many elections in the first half of 2012 (42) as they did in the first half of 2011 (20). They also saw unions successfully thwart eight decertification efforts—a big change from last year, when employers were nine-for-nine in decertification elections in the first half of the year.

• SEIU. It’s been an uncharacteristically quiet year for service workers. Through June, SEIU participated in 45 fewer elections, and organized almost 4,400 fewer workers, than in the first half of 2011.

• Small employers. Companies with fewer than 100 workers continue to face tougher odds than their larger counterparts. By the halfway mark of both this year and last year, small employers saw unions prevail in two-thirds of their elections, while larger companies basically broke even.

• Steelworkers. Of the 1,774 workers covered under NLRB elections involving the United Steelworkers, the union succeeded in organizing only one-quarter of them (26 percent), far below the success rates of other major industrial unions like the International Association of Machinists, International Union of Operating Engineers, and International Brotherhood of Teamsters.

• Texas unions. The Lone Star State has never been a hotbed of union activity, but this year has been even cooler than normal. Unions have won only three elections through June, for a 27 percent win rate.
