They are the AP Directives, they were leaked years ago and have been updated since then, it’s basically a list of things allowed and not allowed.
Ultimately, you can only be coached with the cameras based on AP related things (Security, Safety, Conduct) but not performance related stuff. If they coach for performance based on the cameras it’s a violation of these directives and they should get in trouble for it. However, they gave DTLs access to cameras ON THEIR PHONES, and they have no reason to actually have this. Most people that are willing to be a DTL are crazy, and there is no way they follow the rules and use them to spy on stores.
