From the Highlights: "The SCA [Service Contract Act] ensures that service workers on certain federal contracts receive pay and benefits that reflect current employment conditions in their locality.

This testimony describes (1) what available data reveal about past SCA cases, (2) challenges DOL [U.S. Department of Labor] reports facing in enforcing the SCA, and (3) SCA implementation challenges."
