This article is concerned with the moral economy of HIV treatment in a transnational mining company. Based on multi-sited ethnography in the world's third biggest mining company, I explore how relations between employer and employee are being transformed as a result of corporate HIV programmes, creating connections between the personal realm of sexual conduct and family life and the political economy of global corporate capitalism. I argue that corporate social responsibility serves as a mechanism through which the company consolidates its authority over a particular field of society, in this case its workforce, conflating the exigencies of human care with the interests of capital.
