In September 2015, there was a 23 percent vacancy rate among correctional officers, who appeared to be leaving for higher-paying jobs with benefits. As a result, the audit found, CoreCivic required long-term mandatory overtime and had to shutter essential security posts, making it harder to respond to emergencies and control access in and out of the facility. The failure to "consistently fill these posts compromised its ability to run the facility in a safe and secure manner," the auditors wrote.
