It seems to be the way of the future. In the past few years, five of the government agencies I work with have moved to open plan solutions.
The biggest one probably has about 400 people on a single floor. No cubicles, no assigned desks, no assigned lockers. Each evening you put everything from your desk (well it is actually a table – no drawers) into any free locker and every morning you take everything out and sit at an available desk. The morning rush to get to the tables near the windows has to be seen to be believed!
They tend to range from too noisy to too quiet. Management (who usually do not work in the open plan office themselves) tend to like them due to the vast financial savings because many people work from home or in the field and were never at their desks anyway. Staff (particularly those with autism spectrum disorders, concentration difficulties, allergies or hearing aids) tend to find it quite stressful but many others don’t seem to mind. My guess is that most people would still prefer to have their own office.
I am not sure I could work like that, though many people would say my situation is worse because I work in other peoples’ workplaces. My office is my handbag, my meeting room is their sofa, for example.
