Temporary work or temporary employment refers to an employment situation where the working arrangement is limited to a certain period of time based on the needs of the employing organization. Temporary employees are sometimes called "contractual", "seasonal", "interim", "casual staff", "outsourcing", "freelance"; or the words may be shortened to "temps". In some instances, temporary, highly skilled professionals refer to themselves as consultants. Increasingly, executive-level positions are also filled with interim executives or fractional executives.

Labour economics, or labor economics, seeks to understand the functioning and dynamics of the markets for wage labour. Labour is a commodity that is supplied by labourers, usually in exchange for a wage paid by demanding firms. Because these labourers exist as parts of a social, institutional, or political system, labour economics must also account for social, cultural and political variables.
