Social work is facing fundamental changes and challenges. Neo-liberalism, globalization, corporate management and the mixed economy of welfare have transformed the profession by undermining former certainties of practice. "Clients" have added their own voice to the need for new models of service delivery. Social Work engages with the dilemmas and opportunities emanating from the contested nature of practice. Using a broad range of theories, this book outlines the knowledge, skills and values that enable practitioners to respond more effectively to the demands of working in fluid and constantly changing contexts. Underpinning the approach that it takes is the idea that "clients" are citizens with social and human rights which have to be respected. This provides the intellectual basis for a practice rooted in the ideas of citizenship, solidarity and reciprocity, thus reformulating the relationship between "clients" and society. This important new textbook provides a comprehensive introduction to the dilemmas and tensions that practitioners are compelled to resolve in their daily work. It will be invaluable for students taking courses in social work, social welfare and applied sociology as well as nursing and health professionals, social work practitioners and policymakers.
