About the Study

In 2019, the Chief Evaluation Office’s Evaluation Technical Support contract, implemented by Manhattan Strategy Group, partnered with the W.E. Upjohn Institute for Employment Research to produce a paper on contingent and alternative employment in the United States, Contingent and Alternative Employment: Lessons from the Contingent Worker Supplement, 1995-2017. This paper uses data from the Current Population Survey’s (CPS) Contingent Worker Supplement (CWS) to analyze trends in contingent work and provides an in-depth picture of the nature of contingent and alternative work in the United States and how employment arrangements are changing.

This Department of Labor-funded study contributes to the growing labor evidence-base to inform worker protection, labor standards, and workplace-related benefits programs and policies and addresses Department strategic goals and priorities.

The Department of Labor’s (DOL) Chief Evaluation Office (CEO) sponsors independent evaluations and research, primarily conducted by external, third-party contractors in accordance with the Department of Labor Evaluation Policy. CEO’s research development process includes extensive technical review at the design, data collection and analysis stage, including: external contractor review and OMB review and approval of data collection methods and instruments per the Paperwork Reduction Act (PRA), Institutional Review Board (IRB) review to ensure studies adhere to the highest ethical standards, review by academic peers (e.g., Technical Working Groups), and inputs from relevant DOL agency and program officials and CEO technical staff. Final reports undergo an additional independent expert technical review and a review for Section 508 compliance prior to publication. The resulting reports represent findings from this independent research and do not represent DOL positions or policies.
