They enforce rules, maintain security by preventing disturbances and escapes, inspect facilities for contraband and rule violations, review mail and visitors, write reports, and escort inmates to courtrooms and medical facilities. Officers work full-time on rotating shifts around the clock, including weekends and holidays. The median annual wage for correctional officers was $43,540 in May 2017, ranging from under $29,540 to over $74,940.
