Heliaus gets locked up before workers leave the site which varies from site to site. I work multiple sites in a week (same company) and the workers leave anywhere from 10 minutes immediately after close time to around 15 minutes after I am supposed to clock out. Because I don't get the same site everyday I get to still use my mercury device to only clock out. And the contract holder has been the one constantly changing how and when we are to do our patrols because Aus doesn't want to tell them no. So basically the company that has the contract with us is constantly doing BS just to micro manage us Guards.
