In the past, they weren't able to demand ANY medical records, unless you needed a special exemption (fmla, excuse of absence, special accommodations, work restrictions, etc.), they were never allowed to demand records as a routine part of employment. And even then, they were not allowed to ask for the medical condition, just what the specific accommodations/restrictions are, or that an absence was medically excused.
This IS a major change in the expectations of medical privacy. But your doublethink programing is so complete you literally are incapable of seeing that. You can be convinced that 2+2=5. I don't even know why I'm bothering.
I know that this is going to happen. I know that I can't change it. But it's frustrating to see how brainwashed people, in general, have become. They can literally see the change happening before them and still believe that no change is happening.
