Spanish Syndical Organization
The Spanish Syndical Organization (Spanish: Organización Sindical Española; OSE), popularly known in Spain as the Sindicato Vertical (the "Vertical Trade Union"), was the sole legal trade union for most of the Francoist dictatorship. A public-law entity created in 1940 and defined as subordinate to the ruling party FET y de las JONS, the vertically structured OSE was a core part of the project for frameworking the Economy and the State in Francoist Spain, following the trend of the new type of "harmonicist" and corporatist understanding of labour relations vouching for worker–employer collaboration developed in totalitarian regimes such as those of Nazi Germany and Fascist Italy in the first half of the 20th century.
