Final answer:
A complaint against a regulated member typically must be in writing to create an official record, may be submitted by parties other than just clients, such as employees or their representatives, and while anonymity can be protected, complete anonymity may not be always allowed.
Step-by-step explanation:
A complaint against a regulated member is commonly addressed within the realm of legal and regulatory frameworks. These complaints are typically required to be in writing to ensure there is a formal record of the concerns being raised. There are instances, like with complaints to OSHA, where current workers or their representatives may file a complaint if they believe there is a serious hazard or that their employer is not following standards. Importantly, workers have the right to request an inspection without revealing their identity to their employer, and these rights are protected by law to prevent retaliation.
In terms of who can submit a complaint, it is not necessarily limited to clients. Employees, representatives, or even members of the public may be eligible to raise concerns depending on the specific rules governing the regulated member or entity. Also, while anonymity in complaints can be protected, as in the case of OSHA, complete anonymity may not always be allowable in other regulatory contexts where follow-up and investigation are required.
