This article draws on a body of research conducted by the author over the past ten years on the social organization of nursing work. It explores questions surrounding nurses' contemporary labor process control and its meaning for nurses' professionalization and proletarianization. Both are dynamic processes, changing as public administration of the Canadian health care system changes and as nurses are successful in winning more complete self-regulation. Nurses are currently being articulated more and more securely to dominant ideas of public sector management through textually mediated technologies. Nurses find new upwardly mobile careers and challenging, responsible, and more respected work. However, as the generation of objective information for professional accountability, cost-accounting, and managerial decision-making becomes unified in computerized patient information systems, producing and using such information becomes a central and determining core of everyday nursing work. It organizes nurses into a "managed" practice of patient care, contradictory for them in many ways. Outstanding among these contradictions is a new professionalized standpoint of cost-efficiency that subordinates nurses' traditional interests and grounding of their work in the standpoint of care.
