Which type of complaint is made by a party who does not reveal their identity?

An anonymous complaint is submitted by a party that chooses not to disclose their identity. This type of complaint allows individuals to report issues or concerns without fear of personal repercussions or exposure, which can encourage more people to come forward with information they might otherwise keep to themselves. These complaints can cover a range of issues, such as workplace misconduct or safety violations, and are often taken seriously by organizations as they can highlight areas needing attention or improvement.

In contrast, a formal complaint requires the complainant to provide their identity and is usually tied to procedures that involve direct accountability. An internal complaint generally relates to issues raised within an organization or company by someone who is known. A public complaint, on the other hand, is often aired openly and typically involves issues that may impact broader communities, but still would involve the identity of the complainant being known. The essence of the anonymous complaint lies in its confidentiality, making it distinct from the other types.
