You must be hard-working and attentive to become a guard. Long working hours, and every day is a life or death situation. You may be involved in a fight with an inmate that is uncontrollable and a deadly weapon is present. Guards should always keep a distance between the inmates and their personal lives to avoid accusations of crime. According to Banks, knowledge ability relates to the need for guards to understand the informal rules and processes that shape daily prison interactions and how to avoid being manipulated by inmates (pp.153).
Guards also experience corruption in the prison as well. Prisoners may bribe a guard into smuggling drugs into their cell. As a result of this, the guard may encounter an altercation with the same inmate, and an accusation of rape may be reported to get that particular guard in trouble. Always avoid personal relationships with inmates to avoid conflict.
