According to the National Labor Relations Board, unions won 66.8% of representation elections held in 2008. That number represents a more than 10% improvement over 2007 and is the highest win rate since such data started being tracked in 1984.

According to the Bureau of Labor Statistics’ latest data, the number of union members in the U.S. increased by 428,000 in 2008 to 16.1 million, or 12.4% of employed workers.

Business advocates have been quick to jump on the above data as evidence that there is no compelling need for the Employee Free Choice Act (EFCA).
