I used to work in an IT call center like that. It wasn't even dark it was just dim because no one wanted the light over their desk turned on. There was enough light from the kitchenette area and the walkways to easily see. We got a new manager that hated that we all wanted the lights off so she used like 3 people who complained about it (and were in a corner of the room with the lights on so... stfu) as a pretext to do a poll to keep the rest of the lights turned on. She came back saying there was "a lot of" support for turning the lights on so now it was required but refused to release the results. Immediately lost all respect from the room. She would have eventually anyway because she was a shit manager but that was like right out of the gate.
