I used to work in a fairly secure government data center. I was a facility electrician, but also sat on lower-level hire boards (i.e. blue collars). My RFID would grant me access anywhere across multiple facilities.

>It's the lack of communication when people are fired.

Arriving to work, I observed the long-time janitor, whom I'd helped hire and knew very well, stuck at the entryway. He was extremely helpful albeit not too bright — I had no reason to suspect his badge had been deactivated (==fired) so I badged him in (our offices adjoined).

Janny went to work, a typical Monday, following others to clean construction-related debris (he just thought his badge broke).

Not until he tried to return from lunch, was he informed that his employment had been terminated. When I asked the facility manager "WTF, dude?!" he made some snide remark about "ooops I forgot to tell him — don't worry they're able to land on their feet anywhere" (janny was a non-white citizen).

Started looking for a new jobsite immediately after this. Ignorance and hatred are odd bed-fellows.
