Establishment means a public or private economic employing unit generally at a single physical location which produces and/or sells goods or services, for example, a mine, factory, store, farm, orchard or ranch. It is usually engaged in one, or predominantly one, type of commercial or governmental activity. Each branch or subsidiary unit of a large employer in a geographical area or community must be considered an individual establishment, except that all such units in the same physical location is considered a single establishment. A component of an establishment which may not be located in the same physical structure (such as the warehouse of a department store) also must be considered as part of the parent establishment. For the purpose of the seasonal farmworker definition, farm labor contractors and crew leaders are not considered establishments; it is the organizations to which they supply the workers that are the establishments.
