Ciaran Casey emigrated from Ireland to Sweden in 1975.  Two decades later he was elected International Secretary of his union, the Central Organisation of Swedish Workers (SAC), and Workers Solidarity interviewed him for their Spring 1995 issue.  The SAC, formed in 1910, describes itself as “syndicalist and libertarian socialist”.

It is affiliated to the Red & Black Co-ordination of “unions following the tradition of self-management, anti-authoritarian, anarcho-syndicalist and federalist internationalist labour movement”.  Other affiliates are from Spain, Italy, France, Greece and Poland.
