Corrections Officers are responsible for the care, custody, and control of individuals who have been arrested and are awaiting trial while on remand or who have been convicted of a crime and sentenced to serve time in a prison or jail.
Most officers are employed by the government of the jurisdiction in which they operate, though some are employed by private companies.
