A Voz do Trabalhador (English: The Worker's Voice) was an anarchist periodical published in Brazil whose main theme was the relationship between anarchism and syndicalism.

In addition to this issue, others such as police repression, the high cost of living, solidarity between workers and even libertarian theater and literature were discussed in its pages.

Among these journalists, in addition to Neno Vasco, were Marcelo Varema, Jagunço, A Barão, Albino Moreira, João Penteado, Amaro de Matos, Manuel Moscoso, Eurípedes Floreal, José Martins and even Lima Barreto, the famous Rio writer and novelist.

Lima wrote a chronicle, entitled "Words of an anarchist snob", taking a stand against the official repression promoted by the republican government against immigrants accused of anarchism.

[2] Although the militants of anarcho-syndicalism formed a minority, among immigrant workers and Brazilians, the political demands of this group were of paramount importance in the history of some basic labor conquests.
