Final answer:
Top-level managers provide support to middle managers, first-line managers, and operating workers in an organization, but not to the chairman of the board, who is part of the governance structure responsible for oversight.
Step-by-step explanation:
The job of top-level managers is to support the organizational hierarchy beneath them, which includes various managerial levels and operating workers. Generally, these top-level managers are responsible for overseeing and providing resources and guidance to middle managers, first-line managers, and operating workers. However, their role does not typically involve providing support to the chairman of the board.
The board of directors, including the chairman, is above top-level managers and usually plays a role in governance and oversight, ensuring that the company operates in the best interests of the shareholders. The relationship between managers and the board is not one of support but rather one of accountability and reporting. In an organizational structure, this distinction is essential in understanding the flow of responsibilities and the support system implemented within an organization.
