Labour Party (UK)
The 1910 election saw 42 Labour MPs elected to the House of Commons, a significant victory since, a year before the election, the House of Lords had passed the Osborne judgment ruling that Trades Unions in the United Kingdom could no longer donate money to fund the election campaigns and wages of Labour MPs. The governing Liberals were unwilling to repeal this judicial decision with primary legislation. The height of Liberal compromise was to introduce a wage for Members of Parliament to remove the need to involve the Trade Unions. By 1913, faced with the opposition of the largest Trades Unions, the Liberal government passed the Trade Disputes Act to allow Trade Unions to fund Labour MPs once more.

Trump tariffs
Beginning on June 1, 2018, the Trump administration imposed a 25% tariff on imports of steel, and a 10% tariff on aluminum, on the European Union, Canada, and Mexico. The tariffs angered U.S. allies, who planned retaliatory tariffs on U.S. goods, and heightened chances of a trade war. China said that it will retaliate for the tariffs imposed on $50 billion of Chinese goods that come into effect on July 6. India is also planning to hit back to recoup trade penalties of $241 million on $1.2 billion worth of Indian steel and aluminium.

Since at least the mid-19th century, numerous concepts for a union among Canada, Mexico and the United States of America, some including the Caribbean, the Central American and the South American countries, have been proposed, such as the North American Technate. Following the North American Free Trade Agreement (NAFTA) and the Maastricht Treaty going into effect there was speculation about the formation of a North American Union, similar to the European Union created by Maastricht, being a possible future step for the region. Several proposals for continental integration of North America advocated the creation of a union styled after the European Union, though many academic and business groups advocated less dramatic changes involving the formation of a customs union or common market.

The American Federation of Labor (AFL) organized as an association of trade unions in 1886. The organization emerged from a dispute with the Knights of Labor (K of L) organization, in which the leadership of that organization solicited locals of various craft unions to withdraw from their International organizations and to affiliate with the K of L directly, an action which would have taken funds from the various unions and enriched the K of L's coffers. The Federation of Organized Trades and Labor Unions also merged into what would become the American Federation of Labor.
