On the other hand, you can also argue that people who want to WFO to get their dose of social interaction are forcing those who would want to WFH to provide that dose when they would rather not. That seems to be the mismatch in many WFH vs. WFO vs. "do what you want" arguments. The people that want WFO need the majority of their coworkers to also WFO to get whatever benefit they derive from WFO. In a flexible setting where you can choose to WFO or WFH, what happens to the WFO person when the majority of their coworkers choose to WFH? On the other hand, the WFH person could care less if their coworkers are WFO or WFH.
