I would literally switch jobs (and perhaps careers, if every company was like this) if forced to work in an open office like this. I cannot work that way; I can't focus. I realize that I'm adding nothing constructive to this thread; I don't care. Maybe some manager somewhere will see this and a hundred other anecdotal opinions and think twice about open offices. I am the opposite of a prima donna. I just want to work…
Isn't the notion that private offices are better than open floor plans disproven by reality? Tech companies predominantly use open floor plans and these same companies are some of the most successful in the world. What companies would proponents of private offices point to as counterexamples?
That said, a common reason for it is back-door age discrimination. Plenty of companies use open-plan offices without such an intent (they "look" busy, which pays off in marketing, and they're cheap) but the open-plan fetishism is all about "culture fit", meaning exclusion of the old, the female, the lower-than-upper-middle-class, and all disabilities except early stage alcoholism.
Tech companies are, in general, very badly managed. It doesn't prevent them from being successful because technology is so powerful that it compensates for inept management. I see this as a good thing in the long term (imagine what this industry could do if it wasn't run by idiots) but, culturally, it's bad because the worst attributes of "startup culture" are infecting the whole economy.
