The provision of temporary workers to handle a particular facility, department, or function for an organization. The first-line supervision of these workers is sometimes managed through the temporary employer, ultimate supervision, and management responsibility for the product or service of the department, or the outsourced function, is retained by the customer. These are considered to be temporary help arrangements, even though they may be for an indefinite period. It is often a way to maintain high productivity in high-turnover, high-burnout positions such as telephone work, data-entry operations, or repetitive assembly work.
