Národní sdružení odborových organizací

[5][6] Its ideological precursor Všeodborové sdružení ('All Trade Union Association') was founded on January 26, 1910, changing its name to Česká dělnická jednota ('Czech Workers Unity') in 1912.

[1][2] Whilst smaller than the main trade union centres, it functioned as a gathering point for right-wing workers.

[4] In August 1929, the Svaz báňských, střelců a dozorců v Moravské Ostravě ('Union of Mining Shooters and Supervisors of Moravian Ostrava'), with 425 members, affiliated itself with the organization but maintained themselves as an autonomous unit.

[10][4] In 1931, the organization won 110 seats in the Ostrava district in the mine workers council elections.

[7] With the emergence of the Second Czechoslovak Republic, the organization formed a coalition with the Republikánské ústředí zaměstnanců ('Republican Employees' Centre') and three smaller unions.
