Modern corrections officers, aside from frequently putting their lives on the line, are a combination of police officers, social workers, counselors, security specialists, managers, and teachers. A corrections officer oversees individuals who have been arrested, are awaiting trials, or who have been convicted and sentenced to jail (TPR Education IP Holdings, LLC, 2012). A corrections officer in a small county jail or precinct station house may also serve as deputy sheriff or police officer, whereas an officer in a large state and federal prison will have highly specialized duties, such as overseeing prisoner transfers. Working conditions can either be indoors or outdoors, depending on an officer's duties, and indoor environments can range from perfectly acceptable to overcrowded, hot, and noisy (TPR Education IP Holdings, LLC, 2012).
