Stanford economist Nicholas Bloom, one of the most-cited researchers on this exact question, has tracked remote and hybrid work productivity for years — his research finds fully remote work has mixed effects on individual output but that hybrid arrangements (a few set days in-office) tend to boost both productivity and retention, largely by cutting commute time without losing in-person collaboration entirely. Meanwhile, major companies like Amazon, JPMorgan, and others have pushed hard return-to-office mandates, citing collaboration, mentorship, and company culture as things that quietly erode over video calls even when individual task output looks fine on paper.
