Is it possible for someone to 1. Be a really good 'in person' manager (able to foster a good in-office culture, motivate and coach people effectively in real time). 2. Be a really bad 'remote' manager. Not saying RTO mandates are a good idea, but to say it's masking poor management as a black and white statement lacks nuance.
Managing a remote team is much harder than managing an in-person team.
