Protect Our Workers Act of 2023 This bill requires the U.S. Army Corps of Engineers to provide to each Corps district clarifying, uniform guidance with respect to prevailing wage (i.e., Davis-Bacon Act) requirements for government contractors and subcontractors. This guidance must conform with the Department of Labor's regulations, policies, and guidance for implementation of the Davis-Bacon Act, such as proper classification of all crafts by federal construction contractors and subcontractors; direct districts to investigate worker and third-party complaints within 30 days of their filing; and instruct districts that certified payroll reports submitted by contractors and subcontractors shall be publicly available and are not exempt from disclosure under the Freedom of Information Act.
