Day labourers, radical unionism and collective action in Andalusia.

This article analyses the strategies and the collective action of radical agrarian trade unions in Andalusia (the southern region of Spain) from the Political Transition until today. It traces the origins, evolution and recent transformations of the radical day labourer organisation, the Land Workers Union (Sindicato de Obreros del Campo) and the Andalusian Union of Workers (Sindicato Andaluz de Trabajadores). The article outlines the main factors for the survival of these organisations by using a synthetic and eclectic theoretical approach to collective action. [ABSTRACT FROM PUBLISHER]
