In the current era of providing health care under pressure, considerable strain has been placed on nurses' workplaces. Underneath the economic and organizational challenges prevalent in health-care delivery today are important values that shape the ethical climate in workplaces and affect the well-being of nurses, managers, patients and families. In this article, the authors report on the outcomes of Leadership for Ethical Policy and Practice, a three-year participatory action research study involving nurses, managers and other health-care team members in organizations throughout British Columbia. By using an ethics lens to look at problems, participants brought ethical concerns out into the open and were able to gain new insights and identify strategies for action to improve the ethical climate. Nurse leader support was essential for initiating and sustaining projects at six practice sites.
