Social workers must develop a sensitive yet informed approach when working with service users from different social and cultural groups. In many aspects of life, including accessing human services, people are marginalised, ignored, stigmatised or discriminated against because of one or more aspects of their identity: age, sexual orientation, faith or belief, gender, race or ethnicity, social class, and disability. This book acts as a guide for students to develop their understanding of these various groups while illustrating how the social work value base can be a central part of such understanding.
