The American Working Conditions Survey (AWCS) is a survey of individuals designed to collect detailed information on a broad range of working conditions in the American workplace. The AWCS was fielded in 2015 on the RAND American Life Panel, a nationally representative (when weighted) sample of individuals residing in the United States who have agreed to participate in regular online surveys.
