Which of the following reflects a violation of established rights?

The choice that represents a violation of established rights is the failure to act when aware of abuse. In the context of corrections, staff members have a legal and ethical obligation to report and address any known instances of abuse or misconduct. This duty stems from the responsibility to protect the rights and welfare of inmates, ensuring a safe environment.

When an individual in a position of authority or responsibility becomes aware of abuse but chooses not to intervene or report it, they are failing to uphold the standards of care and protection mandated by law, institutional policies, and ethical guidelines. This inaction can lead to further harm to the victim and perpetuates a culture of silence and complicity regarding abuse.

In contrast, insubordination might indicate a failure to follow orders but does not directly infringe on the rights of others. Lack of policy adherence could lead to operational issues but does not inherently reflect a violation of individual rights unless it specifically pertains to the treatment of individuals within the system. Disagreements with peers, while potentially disruptive, are a normal part of any workplace and do not typically involve a violation of rights. Thus, the failure to act when aware of abuse is the clear violation of established rights in a corrections environment.
