Employment Agency
Since the beginning of the twentieth century, every developed country has created a public employment agency as a way to combat unemployment and help people find work.
In the United Kingdom the first agency was began in London, through the Labour Bureau (London) Act 1902, and subsequently nationwide by the Labour/Liberal government through the Labour Exchanges Act 1909. The present public provider of job search help is called Jobcentre plus.
In the United States, a federal programme of employment services was rolled out in the New Deal. The initial legislation was called the Wagner-Peyser Act of 1933 and more recently job services happen through one-stop centres established by the Workforce Investment Act of 1998.
Head Hunters
A recruiter is someone engaging in recruitment, which is the solicitation of individuals to fill jobs or positions within any group, such as a corporation or sports team. Recruiters may work within an organization (typically in its Human Resources department) or on an outsourced basis. Outsourced recruiters working for multiple clients in a third-party broker relationship, and are variously called headhunters, search firms, agency recruiters, recruitment consultants or agents.
Personnel Selection
Personnel selection is the process used to hire (or, less commonly, promote) individuals. Although the term can apply to all aspects of the process (recruitment, selection, hiring, acculturation, etc.) the most common meaning focuses on the selection of workers.
