Social work is an academic discipline of social sciences and humanities where the main focus is to improve the social structure of the society and help the weak and underprivileged people of the community. Social workers work with individual, families and communities, and deal with issues related to social empowerment like poverty, unemployment and education.
Social workers work in varied fields, from working for the upliftment of the poor and oppressed, to working with children with special needs, there are a lot of ways that a social worker can contribute through their work. There are many other kinds as well, and students generally choose their specialisation after working a bit to gain experience in one particular field.
