If you want people to return to the office, then make the working conditions at the office desirable to return to. Yes, free meals, interesting spaces, massage rooms, etc are all great perks. But you’re there to work, and the reality is hoteling, no shred of privacy (need to have an ad hoc phone conversation with someone somewhere else? Good luck booking a phone room and walking 10min to get there). If you want people in the office, give them offices. Small, glass-walled, but acoustically private. And above all, assigned, so that you can personalize it a little and not mind sitting there for 8-12 hours.
