The open office I worked in was pretty much the worst case of the open offices. We were 10 people to a side. We had about a 5' "desk" with a quarter height partition wall in front of us. A single file cabinet. There were about 4' aisles between the rows.
The company I worked for did not do this as any part of collaboration or team building, or any of the other baloney you hear. They simply needed to cram 500 people into a space designed for 200. Of course they didn't take parking into account, and if you weren't at the office by 7am it was like trying to find a spot at the mall before Christmas. There were no phone booth areas where you could take a private phone call. The conference room layout was geared for the 200 person layout. You had to reserve a conference room 3 weeks in advance.
Man it sucked. It was like the day room at general population in prison. I felt like the guy in office space muttering under his breath. If the person next to me spread out their papers and they inched into my space, it was disturbing. Your 6' of space were treasured. You had zero privacy. For anything. I know, I know, "don't surf the web at work," but a lot of what I did at work contained confidential data. I could hear the conference calls from people 4 rows over. You got so used to there being no privacy you overheard incredibly personal phone calls because there wasn't anywhere else to have them. Go outside? It was winter in New England.
