How does an organization's structure affect organizational behavior? Strict structure and hierarchy keep employees working together effectively with the full organizational staff regardless of geographical location. Structures vary in response to the cultural behavior of clients and new hires that influence the organization. Lines of communication are informal, so employees can pick and choose the levels of management that need the information and filter their messages accordingly. Work roles, functions, and responsibilities are usually well defined, which reduces anxiety because employees are clear on the expectations for their duties
