Jockeys are normally self employed, nominated by horse trainers to ride their horses in races, for a fee (which is paid regardless of the prize money the horse earns for a race) and a percentage of the purse winnings. In Australia, employment of apprentice jockeys is in terms of indenture to a master (a trainer); and there is a clear employee/employer relationship. When an apprentice jockey finishes his apprenticeship and becomes a "fully fledged jockey", the nature of their employment and insurance requirements change because they are regarded as "freelance", like contractors. Jockeys often cease their riding careers to take up other employment in racing, usually as trainers. In this way the apprenticeship system serves to induct young people into racing employment.
