The popular version of social exclusion has given rise to various forms of welfare-to-work initiatives in most developed capitalist nations. Social inclusion, therefore, is commonly assumed to be achieved through paid work. The delivery of social welfare through employment activation programmes is consequential, as it necessitates an unusual cooperation between the welfare state and the labour market. With a focus on Ontario Works, a relatively mature example of Canada's residualized social welfare services, this article is an empirical analysis of the social space in which the state and the market merge – by design – and the resulting processes and outcomes of social exclusion that operate for women who parent alone. I begin with a brief review of the most popular concept of social exclusion, and the pre-eminent place of paid work in related social policy responses, followed by a consideration of the ideological context producing and reinforced by work-first programmes. Our attention is turned to a reconfigured notion of social exclusion as process and outcome, spontaneously set in motion and self-perpetuating in the fused market–state social field. Through a case study of lone mother experiences of Ontario Works, the specific ideological practices through which welfare-to-work strategies operate to keep women in their place are described. I argue that the analysis of the market-state as a unified social field – ordered according to the paired ideologies of market neo-liberalism and conservative 'family values'– is necessary for conceiving policy responses that are effective in interrupting the dynamic process–outcome iterations of social exclusion
