This essay is a speculative exercise undertaken with the purpose of debating afresh one of the most hoary themes in the history of the working class - the question of intervention and agency. The subject is vast, and I will not pretend to have arrived at any definitive conclusion. The observations set out here are not based on an all-encompassing survey of labour history, but may be substantiated in a reading of some of my earlier research to which references will be provided. The exercise will begin with a consideration of certain well-worn positions, but will then attempt to analyse the functional notions of space and boundary inherent in the repeated use of the term outside',outsider’, "from without", etc in the language of managements and unionists of different hues. I will suggest that the question of the Outside is not merely one of the origins of consciousness (to which suffixes such as adequate',socialist’, `historical’, etc may be attached as per ideological preference), but also, and perhaps primarily, one of class domination and class power. Hence I will suggest an expansion of the historiographical use of the term. It is also about the types of plebeian agency and initiative, which the hegemons of labour found acceptable, versus those, which endangered their position and required to be thwarted in the immediate sense and disregarded historically.
