Social work is work done to help society. A social worker is a government employee that gives adequate welfare and helps people who cannot help themselves including physically disabled people, person with other disabilities, people addicted to alcohol, and people with addictions to drugs like cocaine and marijuana. This person helps the disadvantaged person acquire a normal life (job, home, money, etc.) If a child is being abused then a social worker could help by either taking the child away to live in a home or to be fostered. Social workers are provided by the government.
