A protection officer is a type of security guard who monitors a facility during and after business hours to prevent theft, damage, and other types of loss. Typical job duties involve interacting with employees, observing customers and clients, and patrolling the grounds. As a protection officer, you must document any information related to incidents of theft, damage, and loss. Most protection officers are not law enforcement officials, so when you are faced with a criminal situation, you call law enforcement and provide support to these officers on the scene. There are different levels for this career, and the higher levels may require more responsibility and potentially armed guarding duties.
