A social worker helps individuals overcome difficult life circumstances, such as developmental disabilities, drug abuse problems, homelessness, bankruptcy, or domestic abuse. There are many different types of social worker jobs, as professionals usually specialize in children and family services, mental health treatment, drug abuse counseling, or public health. Other social worker jobs may involve administrative work, research, and policymaking. Social workers in all settings are typically compassionate, good listeners and communicators, and knowledgeable about laws and ethics.

Family services social workers provide counseling and resources to people who are struggling to maintain healthy relationships. They may help single parents find financial assistance, initiate marriage or family counseling, or determine the need for refuge for abused children or spouses. Many social workers specialize in helping children analyze their social, behavioral, and school problems. Most children and family services social worker jobs are found in government agencies, though some professionals work for private counseling practices, schools, or nonprofit groups.

Professionals who hold mental health or substance abuse social worker jobs help people come to terms with their conditions and work towards positive solutions. A mental health worker usually communicates with doctors, caregivers, and psychologists to gain a comprehensive understanding of a person with a developmental disability. He or she might help such a person find suitable housing, employment, or financial resources. Substance abuse social workers counsel individuals who want to free themselves from their addictions and lead normal lives. They explain ongoing care options and help people create healthy life plans.

A social worker may also specialize in public health, awareness, or outreach programs. He or she might counsel patients on their options for obtaining insurance or medical help, or organize followup doctor visits and home care. Many professionals research and organize community awareness programs to inform people about certain public health concerns and what they can do if they are affected by them. Social workers often act as political advisors and community representatives when new public policies are needed.

A bachelor's degree or higher in social work, psychology, or sociology is necessary to obtain social worker jobs in most settings. A new social worker may be required to spend up to two years working as an intern under the supervision of another professional so that he or she can gain firsthand knowledge of the job. Upon successful completion of an internship, an individual becomes eligible to obtain social worker certification in his or her state or country and begin working independently.
