Who is informed of all complaints presented?

The correct answer indicates that the manager is informed of all complaints presented. This is important because the manager typically oversees operations and is responsible for ensuring that customer issues are addressed effectively. By being informed, the manager can take appropriate actions to resolve complaints, analyze patterns in feedback, and implement strategies to improve services or processes.

In a well-functioning organization, the escalation of complaints to a managerial level ensures accountability and allows for a systematic approach to problem-solving, improving customer satisfaction and overall service quality. It also reinforces the idea that complaints are taken seriously and that there is a clear line of communication for escalating issues that require more attention or resources.

The other options focus on more limited groups or departments. While customer service teams and shipping departments may handle specific aspects of the complaints process, they do not possess the broader oversight or decision-making power that managers typically hold. Informing all employees might lead to confusion or unnecessary alarm unless a structured communication plan is in place, as not every employee needs to be involved in the resolution of every complaint.
