Then it sounds like they probably do want to a full return to in-office work, but don't think they can get away with it. If the argument from your leadership doesn't begin with "according to these very clear numbers, our profitability as a business has suffered due to remote work," then it's reasonable to consider what the real reason might be: Wanting to exert control, or the sunk cost fallacy of leasing commercial real estate, or a justification for managers to have someone to manage. Who knows? These things are often not well explained. But anything except an existential business risk is a bad reason as far as I am concerned, when the "resources" so clearly want it to go otherwise.
