> complete inability to read nonverbal cues

Isn't that the default in software departments/companies? However, usually that is considered an "asshole" by the general population, despite actually being a good reason for not reacting to nonverbal communication.

I think it's assholes, for lack of a better term. Instead of respecting your privacy and sending you an email to avoid interrupting you, they think that whatever concern they have is more important and worth interrupting you.
