I agree with OP that unassigned seating and open floor plan is incredibly sub-optimal for white collar folk in general, and especially for those who are producing output of actual value (vs just "pushing paper around"). However, the RTO push is not about employee comfort or productivity. This is intended as a filter to push out some more people without paying severance as both Ford's and the national/global economic conditions deteriorate. I've noted that in my area that this is indeed a dictate coming down from on high and the farther down the chain the less enthusiasm there is for it.
I expect that come March when merits are announced and once again are no more than 3% on average (IE a notable effective pay cut due to two full years of high inflation) that the added cost of commuting cost and time will lead to an exodus of those who can find positions elsewhere. This won't be a concern to management since the strategy going into a recession (or new biz cycle) is to reduce head-count and other structural costs. The Legend said a year ago that those of us in Dearborn are unneeded & undesired, so pushing people out the door by whatever means is aligned with that.
The short of it is to expect the work experience here to become increasingly miserable. "The beatings shall continue until morale improves."
