One dynamic that has become apparent to me recently is that at my company everybody has to justify their building space. If too much sits idle we can be penalized for inefficiency. If half of the employees switch to mostly wfh then the corporation would need to sell off/rent out half of the buildings to avoid this.

As a result they announced that everybody has to be in the office at least 3 days a week, and also most people would be losing their permanent offices and only have access to hotel office space. I've heard rumors that employee retention is becoming something of a concern.
