Sometimes the age/design of the office building is a factor too. When I worked at a large satellite TV provider, a lot of the office space that we had was broken up into offices that couldn’t really be occupied by more than two people at once. Historically, we’d been an aeronautics/electronics company and I think there was some crossover in concept from academic settings, where faculty and researches often have private offices, albeit very small ones for juniors staff. Unless you were on the rungs of management, you usually got either your own interior office or else you shared a window office with another person.
In any event, I can’t imagine that any sensible employer is going to cut up existing walls. Or do they actually do this?

A few times I was on the floor where all the top execs of the electronics company had once worked, mostly private window offices, each one with an admin assistant station in front. Once I picked up a sticky note pad of the type where you pull off the top sheet and stick it on a file or letter to tell somebody what to do with it. In addition to a space where you could write out a few lines of verbal instructions, there were a dozen or more checkboxes for choices like,
[ul]
[li] Come see me[/li][li] Reply[/li][li] Respond, showing me your response first[/li][li] Respond, showing me your response after[/li][li] File[/li][li] Set up meeting…[/li][/ul]
There were many, many more options. I wish I could find an image of this thing to link to, because it was really quite fascinating that these options had to spelled out on the slip.
