A big part of the equation (for some) will be what kind of office they are being asked to return to? At the office my company used to have before it was acquired in 2019 everyone had a cube, not big by any means and not with full walls, but enough space to have a few pics of family, maybe a plant, personal nick-nacks, whatever, a sense of some sort of boundary to it. I could have easily been persuaded to return to that environment 3 days a week, because I did enjoy being around my peers. The acquiring company however, had plans underway to bring us into long elbow-to-elbow tables before work from home happened in March 2020. What would you call a food trough to work at instead of eat at, a "productivity trough"? I am open to tolerating that one day a week for cross team meetings (some have started trickling in already), anymore than that and I am out.
