The gig economy is one of several names used to describe various forms of “gig” work, or small project freelance work. Others include “on demand economy,” “collaborative consumption” and “sharing economy.” Definitions of the gig economy vary widely among commentators. The more narrow definition would include work structured as small projects of a relatively limited duration typically facilitated by an internet platform or app (i.e. freelancing as intermediated by vendors operating in the so-called “human cloud”). Staffing Industry Analysts’ definition is broader than this in that it includes any contingent work of a fixed duration such as temporary workers (sourced directly or through a staffing agency) and independent contractors. We see no reason to limit the concept of a “gig” solely to transactions mediated online. SIA treats the gig economy as synonymous with contingent work and, as such, these workers are sourced and managed through a number of different segments within the Workforce Solutions Ecosystem. Some commentators would also include online services such as Airbnb and Zipcar as part of the gig economy. As these services are not labor-related, SIA regards these services as part of the sharing economy, but not part of the gig economy.
