Contingent work, casual work, or contract work, is an employment relationship with limited job security, payment on a piece work basis, typically part-time (typically with variable hours) that is considered non-permanent. Although there is less job security, freelancers often report incomes higher than their former traditional jobs.

Contingent workers are also often called consultants, freelancers, independent contractors, independent professionals, temporary contract workers or temps.

According to the US Bureau of Labor Statistics (BLS), the nontraditional workforce includes "multiple job holders, contingent and part-time workers, and people in alternative work arrangements". These workers currently represent a substantial portion of the US workforce, and "nearly four out of five employers, in establishments of all sizes and industries, use some form of nontraditional staffing". "People in alternative work arrangements" includes independent contractors, employees of contract companies, workers who are on call, and temporary workers.
