I'd forgotten about it until now, but about five years ago I was working at a gas station here in the US (Mapco, if you're curious). They had one of those cameras inside, making sure we weren't stealing. One day someone calls the phone and says he's watching us, and starts asking us what we're doing and generally trying to intimidate us with this idea that he's going to be monitoring us full-time. The manager got real upset about it, called the higher ups and I'm not sure whatever happened, but he said that it wouldn't be a problem anymore. I kept working that job for another year or so after that, was plenty lazy and ate food on the job (was the solo employee most of the time), goofed off, even left early a few times, and never heard anything about it, so I assume that they really did get rid of that guy, whoever he was.
Seems screwed up now, but at the time I didn't think much about it, just that the security guy who called was an asshole. What's bad now is that it's becoming normalized, to where you can be spied on all the time and no one says anything about it. I suppose privacy will go away completely in the end, it's only inevitable, but it needs to go away for everyone at once, not be used so the government can have Total Information Awareness while protecting every single thing it does as a "state secret."
