And if your team is highly functional already but working from home? What then? What is this nebulous team building you are referring to? I'd challenge you to prove anything you just said with hard data. Just because you say team building works better in person also doesn't hold weight without some evidence. Why 3 days a week? Who decided that was optimal? Why not 1 or 4 or 5? Why not 2 a month?
