During the 1960s the rise of unofficial strike action led the International Socialists to place emphasis on the building of a movement within the trade unions in order to combat the bureaucratic leaders of those organisations. This led to the development of a series of rank and file papers including "The Collier" (Mining), "Redder Tape "(Civil Service), "Rank and File Teacher", etc. These were briefly brought together in a National Rank and File Organising Committee in 1974, the peak of IS influence in the workers' movement.
