A flat structure is an organizational model with few or no levels of middle management between the executives and the frontline workers. In a flat structure, there are few levels of management, and workers report directly to higher-level managers. This means that the role of middle managers is shared between the workers and the higher-level managers, which can lead to greater autonomy and authority for the worker.

Some advantages of a flat structure include faster decision-making and responses, improved communication, and increased employee involvement in the decision-making process. It can also reduce an organizations budget costs by eliminating the salaries of middle management. However, some disadvantages of a flat structure include confusion and possible power struggles among management due to a lack of a specific boss to report to. Flat structures may also limit the long-term growth of an organization.
