Union membership increases for first time in 25 years.

In 2007, “U.S. unions increased their share of membership among workers” for the “first time in the past quarter of a century,” according to the Bureau of Labor Statistics’ (BLS) annual union membership report released today. In the past year, “unions added about 310,000 members, raising the unionized share of the workforce to 12.1 percent from 12.0 percent in 2006.” (HT: Ezra Klein)
