context_page_description: Labor unions in the United States are organizations that represent workers in many industries recognized under US labor law since the 1935 enactment of the National Labor Relations Act. Their activity today centers on collective bargaining over wages, benefits, and working conditions for their membership, and on representing their members in disputes with management over violations of contract provisions. Larger trade unions also typically engage in lobbying activities and electioneering at the state and federal level.
  Most unions in the United States are aligned with one of two larger umbrella organizations: the AFL-CIO created in 1955, and the Change to Win Federation which split from the AFL-CIO in 2005. Both advocate policies and legislation on behalf of workers in the United States and Canada, and take an active role in politics. The AFL-CIO is especially concerned with global trade issues.
  In 2019, there were 14.6 million members in the U.S., down from 17.7 million in 1983. The percentage of workers belonging to a union in the United States was 10.3%, compared to 20.1% in 1983.
context_section_description: Union membership had been declining in the US since 1954, and since 1967, as union membership rates decreased, middle class incomes shrank correspondingly. In 2007, the labor department reported the first increase in union memberships in 25 years and the largest increase since 1979. Most of the recent gains in union membership have been in the service sector while the number of unionized employees in the manufacturing sector has declined. Most of the gains in the service sector have come in West Coast states like California where union membership is now at 16.7% compared with a national average of about 12.1%.  Historically, the rapid growth of public employee unions since the 1960s has served to mask an even more dramatic decline in private-sector union membership.
  At the apex of union density in the 1940s, only about 9.8% of public employees were represented by unions, while 33.9% of private, non-agricultural workers had such representation. In this decade, those proportions have essentially reversed, with 36% of public workers being represented by unions while private sector union density had plummeted to around 7%. The US Bureau of Labor Statistics most recent survey indicates that union membership in the US has risen to 12.4% of all workers, from 12.1% in 2007. For a short period, private sector union membership rebounded, increasing from 7.5% in 2007 to 7.6% in 2008.  However, that trend has since reversed. In 2013 there were 14.5 million members in the U.S., compared with 17.7 million in 1983. In 2013, the percentage of workers belonging to a union was 11.3%, compared to 20.1% in 1983. The rate for the private sector was 6.4%, and for the public sector 35.3%.
  In the ten years 2005 through 2014, the National Labor Relations Board recorded 18,577 labor union representation elections; in 11,086 of these elections (60 percent), the majority of workers voted for union representation. Most of the elections (15,517) were triggered by employee petitions for representation, of which unions won 9,933. Less common were elections caused by employee petitions for decertification (2792, of which unions won 1070), and employer-filed petitions for either representation or decertification (268, of which unions won 85).
