After resigning from the UOD, de los Reyes tried to patch up internal rivalries within the organization but ultimately failed. The UOD was dissolved and in its place was the "Union del Trabajo de Filipinas", headed by writer Lope K. Santos. After this, de los Reyes focused on his "Redencion del Obrero" while contributing to papers like "El Comercio", "Grito del Pueblo", and others. He took up causes such as labor rights, universal suffrage, the exclusion of Chinese immigrant labor, and parity of Filipinos and Americans in the civil service.
