Arrangements between those who perform work and those who provide jobs come in many different forms. Standard work arrangements now exist alongside several nonstandard arrangements: agency work, contract work, and gig work. While standard work arrangements are still the most prevalent types, the rise of nonstandard work arrangements, especially temporary agency, contract, and "gig" arrangements, and the potential effects of these new arrangements on worker health and safety have captured the attention of government, business, labor, and academia. This article describes the major work arrangements in use today, profiles the nonstandard workforce, discusses several legal questions about how established principles of labor and employment law apply to nonstandard work arrangements, summarizes findings published in the past 20 years about the health and safety risks for workers in nonstandard work arrangements, and outlines current research efforts in the area of healthy work design and worker well-being.
