Final answer:
First-level managers are typically responsible for internal issues and often the first to detect problems due to their direct involvement with day-to-day operations and supervision of non-managerial employees.
Step-by-step explanation:
The manager that is typically responsible for internal issues and is often the first to identify problems as they arise is the c) First-level manager. These managers are directly involved in day-to-day operations and closely supervise non-managerial employees. They are on the front lines of the organizational structure, which positions them to spot emerging difficulties before these escalate and reach higher levels of management. First-level managers are pivotal in implementing plans and policies set out by higher management and ensuring operational efficiency at the base level.
In comparison, middle-level managers are generally closer to the top but occupy a position in the middle of the organizational hierarchy, making them less likely to directly observe everyday issues. Top-level and operational managers have different scopes of responsibility, which usually involve broader strategic planning and overseeing the organization's entire operations, respectively. Therefore, first-level managers are best suited for quickly identifying and managing internal issues.
