One of the most intellectually stimulating aspects of working in corrections is the variety of experiences that will be encountered. The primary mission of all correctional facilities is security and control. Each facility achieves its primary mission differently, as well as its secondary missions, such as food distribution, medical care, recreation, and the maintenance of certain minimally acceptable conditions of confinement. Prisons are like schools in that having a common mission does not bring uniformity. Like schools, prisons each have their own personality and favored methods that develop the force of law. Like those in small towns, the networks of personal and social relationships, particularly among the staff, are deep and of a complex weave.
