Defined under the Employment Agencies Act 1973 as the business of supplying people in the employment of the person carrying on the business, to act for, and under the control of, other people in any capacity.
An employment business covers the hiring out of workers on a temporary basis and is frequently called "temping". It has long been associated with the supply of temporary secretarial and other office staff, but has extended into many other areas, including professional and industrial occupations.
Employment businesses are referred to as "temporary work agencies" in the Agency Workers Regulations 2010 (SI 2010/93) and are otherwise frequently referred to as "agencies", "temp agencies" or "employment agencies", and the workers they supply as "agency workers". This can lead to confusion between an organisation that is acting as an employment business and one that is truly acting as an employment agency.
