Who is responsible for investigating allegations of employee misconduct involving discrimination, retaliation, and harassment?

The Office of the Inspector General (OIG) is responsible for investigating allegations of employee misconduct involving discrimination, retaliation, and harassment. This office typically has the mandate to ensure accountability and integrity within the organization. By handling these types of sensitive complaints, the OIG plays a crucial role in protecting employees and maintaining a fair work environment, which aligns with their objective to promote ethical practices and compliance with the law.

Other options may have roles in supporting or managing personnel issues, but they do not have the specific focused mandate to investigate complaints of discrimination, retaliation, and harassment like the OIG does. For instance, the Office of Human Resources often deals with the administrative aspects of employee relations and can provide guidance or support, but they do not conduct investigations. Hence, the OIG's role is pivotal as it allows for an independent examination of serious allegations, helping to uphold the integrity of the organization.
