Swedish Trade Union Confederation

The Swedish Trade Union Confederation (Swedish: Landsorganisationen i Sverige, lit. 'The National Organisation in Sweden'), commonly referred to as LO, is a national trade union centre, an umbrella organisation for thirteen Swedish trade unions that organise mainly "blue-collar" workers. The Confederation, which gathers around 1.5 million employees out of Sweden's 10 million people population, was founded in 1898 by blue-collar unions on the initiative of the 1897 Scandinavian Labour Congress and the Swedish Social Democratic Party, which almost exclusively was made up by trade unions.
