Which building block comprises the various components that make up an organization?

The correct choice is Organization Units. This building block encompasses the different segments or divisions within an organization, illustrating how they interact and relate to one another. Organization Units are essential for defining the structure of a company, detailing the hierarchy, roles, and responsibilities within the workforce. They help in the organization of various departments or functional areas, thus providing a comprehensive framework that details the composition of the entire organization.

In contrast, Jobs and Positions refer specifically to individual roles and responsibilities assigned to employees, focusing on the tasks they perform rather than the broader structure. The Manager Structure deals with the hierarchical layers of management but does not capture the entirety of how the organization is composed. Employee Safety, while critical for ensuring a safe workplace environment, does not pertain to the structure or components of the organization. Hence, Organization Units stand out as the correct answer since it is directly related to the overall composition and organization of a business.
