Final answer:
First-line managers work in all departments or functions of an organization, focusing on day-to-day operations and facilitating a productive environment for team members.
Step-by-step explanation:
First-line managers are positioned at the lowest level of the management hierarchy and they work across various departments within an organization. Their main responsibility lies in overseeing the day-to-day operations and ensuring that their team members are carrying out tasks effectively, contributing to the production of goods and services. This is in contrast to higher-level managers who may focus on broader organizational strategies, goal-setting, and alignment. First-line managers are expected to be adept in relationship building and establishing a positive work environment tailored towards company goals, which can influence job satisfaction and employees' connection with their roles.
