According to the National Association of Social Workers (NASW), social workers help people overcome social and health problems, such as poverty, mental illness, child abuse and neglect, emotional instability, illness, economic uncertainty, domestic violence, homelessness, and drug abuse. They work directly with individuals, couples, families, and groups to identify and overcome these problems. Some social workers also work with communities, organizations, and/or systems to improve services and/or administrate social and health programs. Social workers apply their professional knowledge and skills to help people make the most effective use of their own abilities. When adequate services do not exist in a community, social workers promote the development of new services and programs.
