Community service is unpaid work performed by a person or group of people for the benefit and betterment of their community without any form of compensation. Community service can be distinct from volunteering, since it is not always performed on a voluntary basis and may be compulsory per situation. Although personal benefits may be realized, it may be performed for a variety of reasons including citizenship requirements, a substitution of criminal justice sanctions, requirements of a school or class, and requisites for the receipt of certain benefits.
