While routine background checks provide employers with a one-time snapshot of their employees past criminal history, employers enrolled in federal and state Rap Back programs receive ongoing, real-time notifications and updates about their employees run-ins with law enforcement, including arrests at protests and charges that do not end up in convictions.
