Maybe there are more granular and data-driven conclusions, I'm just someone who sees the benefit of communicating information over vast distances aka the web and appreciate that it's something we can do nowadays.
A message, SMS, phone call, a group call, a skype call or whatever can clear things up right quick.
Plenty times I'll send someone an email because I don't want to engage with someone and the time frame of their reply can be minutes or days. That's fine.
WFH/remote is all about trust from an employer and motivation by an employee.
You're entirely free to communicate as much as you need to whether you're physically present or not. The work gets done or it does not.
I don't really understand the confusion about this.
