We moved into an open office in 2017, nothing new to me. When I started working in the 70's it was the John Baker thing until the late 90's . Then cubicles and offices. The company hypes how the open office increases collaboration and productivity, and all that BS. Truth be told they have 4x the staff in 1/2 the space. I don't see any change in productivity or collaboration. The people who used to hide in their cubicles texting and goofing off do it in the open.
The new place is OK, nothing fantastic, at least the paint and carpets are still clean; the guy who sits across from me is annoying - loud on the phone (I know more than I want to about his life), sneezes and burps loudly - but he's not the only one; that's life.
The one interesting thing about the new place, the idiot architects (in-house staff) didn't make the rest rooms handicapped accessible. Fortunately, we don't have any wheelchair bound people, yet.
