I currently work in a small municipal office, and I think if I were to croak in my cube someone would notice. That said --
The article I read on this incident mentioned that most of the Wells Fargo workers "in" that office work remotely. I believe our colleague, K Frame, was in such a situation during the COVID idiocy, and may still be. Many employers who sent their workers home during the pandemic have been encountering resistance when trying to get workers to return to the hive. I know an IT manager for a major university who has an office in a building the university rents, about half an hour from his home. He hasn't set foot in that building for a year and a half, at least.
I am often the last person to leave on Friday. If I were to die just after everyone else left, the earliest I would be found would be Monday morning. Our office has cubicles, but it's hardly a cube farm -- we have four cubicles, each of which can be seen by both secretaries, and the boss has to walk past them to get into his office. This poor woman apparently WAS in a cube farm, and her cubicle was described as "off the main aisle."
The sad part is, though, that the building has 24/7 "security." One wonders just how diligently "security" actually perform their appointed rounds -- or if they have any appointed rounds at all.
