Social workers, whatever their specialism, practise with people at the margins of society. It is therefore essential that all social work students not only understand the powers and processes that lead to disadvantage and marginalisation but develop the knowledge and skills needed to bring about change and uphold social justice in all aspects of their professional practice. Split into three parts, this book considers what is meant by disadvantage and marginalisation, how this can come about and the impact this may have on lives, before unpicking the key knowledge and skills needed to practice effectively with individuals and groups. It then goes on to show what good ethical and reflective practice looks like, going step-by-step through the ins and outs of using the law and policy to bring about change before considering key ethical dilemmas in practice.
