Union membership in the U.S. grew considerably during the first half of this century, from about 4% in 1901 to a peak of about 33% in the early 1950s. Since then, membership has trended down, prompting unions to focus on increasing their ranks, in some cases by consolidating with other unions into larger and perhaps more powerful organizations. Today, only about 14% of the U.S. workforce is unionized.
