Just anecdotally, I noticed that more junior team members were FAR more willing to ask me for help with something after we were pulled back to the office. That can be mitigated with thoughtful collaboration efforts when operating fully remote, but I didn’t even know they needed help until they could just pop by my desk and ask for something. And they started doing it frequently.

But to be clear, I greatly prefer full remote for myself and again, thoughtful approaches to team management can solve or mitigate a bunch of the remote work downsides, probably.
