Everywhere can be monitored except bathrooms and the actual fitting rooms. Microphones can be deployed(or used to be able to when I worked), but I have never seen or heard of it happening, and needs some pretty high approval because of legal crap. I have put pin-hole cameras in ETL offices personally, so yes they can go in offices too. AP office and booking room are also mandatory. When we used to have the analog setup, we had pinhole cameras mounted inside of fake sprinkler heads, inside duct work, junction boxes, the eye of the eye wash station sign 🙂 had to be the best one.... We move them all the time, so if you find one, just ignore it, unless your stealing. It's not there because your picking your nose or bad mouthing your boss or even on your phone (unless your AP are assholes and wasting resources). We had ETL's ask us all the time to move cameras because they want to catch TM's slacking off or on their phone, we always told them to get lost. And Like some of you have pointed out, we don't have cameras in every dome, so we are not going to waste resources (cameras) on TM's making out in the backroom or texting on the job. I really wouldn't worry about the cameras.
