A social worker with no experience can find employment in different positions in fields like mental health treatment, case management, public assistance, or family services. Your duties in these careers focus on providing social services to clients and acting as an advocate on their behalf when necessary. An entry-level caseworker helps clients find resources and obtain needed services and treatments for themselves and their families. Social work internships can give entry-level workers a chance to learn under the direction of an experienced social worker. A new social worker sometimes performs client visits to assess the needs of clients in their home.
