"Union" redirects here. For other uses, see Union (disambiguation).
Several rudimentary political unions were formed in the 1830s and 1840s, with noteworthy causes including the Merthyr Rising and the Tolpuddle Martyrs. However, one of the first proper trade unions to be established was the Amalgamated Society of Engineers in 1851. The formation of several similar "amalgamated" unions representing different industries followed. Trade union activity peaked in the 1970s, culminating in the 1984 miners' strike, and has since witnessed a decline in membership from a peak of 13.2 million in 1979 to 6.6 million in 2019. Historically, the relationship of Britain's trade unions to the Labour Party has been a key point of contention, and while the biggest trade unions remain affiliated to the party, in 2022 some of most militant unions either remained unaffiliated or were considering disaffiliation.
The first nationwide union in the United States was the Knights of Labor, which was later replaced by the American Federation of Labor. Many unions were targeted by the Pinkerton detective agency. In 1983, 16.2% of private sector workers were unionized; by 2020, the percentage had decreased to 6.3%, even though 65% of people support unionization. Many companies, including Amazon, Google, Nissan, Tesla, Trader Joe's, and Walmart have taken a side against unions.
