Button apparently published by the South African Congress of Trade Unions (SACTU), possibly in Zambia. SACTU was formed in March 1955. Some 33 unions representing 41,253 workers of all races were at the formation conference. The Declaration of Principles Adopted at the Foundation Conference of SACTU adopted at the conference stated "We firmly declare that the interests of all workers are alike, whether they be European or non-European, African, Coloured, Indian, English, Afrikaans or Jewish. We resolve that this co-ordinating body of trade unions shall strive to unite all workers in its ranks, without discrimination, and without prejudice. We resolve that this body shall determinedly seek to further and protect the interests of all workers, and that its guiding motto shall be the universal slogan of working class solidarity: 'AN INJURY TO ONE IS AN INJURY TO ALL.'" SACTU aligned itself with organizations struggling against apartheid including the African National Congress. By the mid-1960s SACTU was effectively banned by the apartheid regime but it continued to operate in exile.
