OK, fair point. I did once get rearranged into an open plan office where all the teams were intermixed for I-still-don't-know-what reason. Half the staff was sales, and yeah, it was impossible to concentrate. Fortunately, we had a liberal work from home policy, so I had a means of escape when I had a deadline approaching. But I still only lasted for a few months after that.

Just to reiterate, I don't think the open plan office was really the fundamental problem. It was the attempt to mix oil and water.
