 The organisation itself claimed to have roots in the trade union activity of the "National-Syndicalist Workers Central" (CONS), founded in 1935.CONS had been, as a result of the process of unification of falangists and traditionalists in 1937, fused with the "National-Syndicalist Employers Central" (CENS) into the National-Syndical Centrals ("Centrales Nacional-Sindicalistas").The idea of organising workers, technicians and employers within one "vertical" structure was also integrated in OSE, and the CNS were incorporated into OSE.
