An office is a space where the employees of an organization perform administrative work in order to support and realize the various goals of the organization. The word office may also denote a position within an organization with specific duties attached to it (see officer, office-holder, official); the latter is an earlier usage, office as place originally referring to the location of one's duty. In the adjective form, the term office may refer to business-related tasks. In law, a company or organization has offices in any place where it has an official presence, even if that presence consists of a storage silo, for example, instead of a more traditional establishment with a desk and chair. An office is also an architectural and design phenomenon, including small offices, such as a bench in the corner of a small business or a room in someone's home (see small office/home office), entire floors of buildings, and massive buildings dedicated entirely to one company. In modern terms, an office is usually the location where white-collar workers carry out their functions.
