News release: “In 2009, the union membership rate–the percent of wage and salary workers who were members of a union–was 12.3 percent, essentially unchanged from 12.4 percent a year earlier, the U.S. Bureau of Labor Statistics reported today. The number of wage and salary workers belonging to unions declined by 771,000 to 15.3 million, largely reflecting the overall drop in employment due to the recession. In 1983, the first year for which comparable union data are available, the union membership rate was 20.1 percent, and there were 17.7 million union workers.”
