Which term refers to a person who complains about actions taken by an employee?

The term that refers to a person who complains about actions taken by an employee is commonly known as the "Complaining Party." This designation is used frequently in various contexts, including legal and workplace environments, to identify the individual or entity that raises concerns or grievances regarding someone's behavior or actions. The complaining party is pivotal in initiating the complaint process, as they provide the basis for the investigation or review of the actions in question, thereby playing a critical role in addressing issues within the workplace or organization.

In contrast, other terms such as "Formal Complainant" may suggest a different context or process level, possibly involving formal procedures or legal actions. "Respondent" refers to the individual or entity that is being accused or complained about, rather than the one making the complaint. Finally, a "Witness" serves to provide information or testimony about an incident but does not necessarily express a complaint themselves. Understanding these distinctions is crucial when navigating complaints and resolutions in any professional environment.
