Social policy is central to social work practice. This textbook is designed to help students, practitioners and academics think critically about the relationship between policy and practice; particularly in how policy both structures and informs practice. Reflective questions help critical thinking and links to websites of substantive information across the UK and internationally help keep you up-to-date with policy developments. The authors’ experience and skills in working with different service user groups combine to provide a constructive and critical approach to working with social policy in an era of welfare retrenchment. Key topics include: discretion and practice; social work training and education; safeguarding children; responses to the needs of looked after children; personalization in adult care; ‘race’ and welfare policy; domestic violence; mental health and capacity; and comparing social work and social care internationally.
