Keeping Carolina clean Posted Jun 4, 2021 When UNC went to remote instruction in March 2020 because of COVID-19, many employees began working from home.

Each weeknight at 11 p.m., the Facilities Services housekeepers of Zone 215 report to the Adams School of Dentistry to clean it so dentists and hygienists can treat patients. (UNC.edu)
