There are valid anecdotes from people being more productive working remote. And there are valid anecdotes from people feeling like remote work has take a toll on their mental health and productivity and ability to collaboratively solve problems. And there are valid anecdotes from people who feel like a balanced hybrid model is exactly what they need. And there's even data that shows hybrid and remote work does improve productivity.
The only opinion I've state as fact is the observation that there does not seem to be one perfect solution for every person and situation and team out there. The only opinion I've truly state is that people should consider compromising on their work requirements because it's silly to rehash an unresolvable argument about which work style is the ultimate global best, ad nauseam.
If I were in charge of this topic at a large company, I do believe this is one of those "every scenario is a bit different" situations and I'd advise managers to work with their teams to make the right call. But I'm not so who cares.
