This hits home for me for a completely different reason. I'm currently hybrid and notice some issues do get fixed faster in the office following that same 90% rule

In the office people don't mind tapping their neighbor on the shoulder 10 times a day to ask how to find/do something. On Slack they feel self conscious about zooming/slacking with someone 10 times in 1 day with questions. It's more about being in your head and feeling like a nuisance online vs. in office, than office being better than remote

This also makes our office days pretty dead in terms of actual progress on projects. Our stronger engineers work much more efficiently at home
