How so? There are still many more people doing fine working from home now than before the pandemic. I would say we probably have enough data to judge that WFH works for some jobs/businesses and not others. I don’t think many people expected every business to switch to 100% permanent WFH. The fact that some companies are pulling back doesn’t mean the experiment has failed.
Or probably just some politics based on beliefs and sensitivities took hold, as often, not specific to this company and topic? ;)
(Otherwise, why not bring up this data to justify something that you know will frustrate some employees?)
