Glad you think this is obvious to you. For many, it's not, which is why we wrote the article...so more people see it as clearly as you do.
As someone who works remote, i would stress that some, if not all, go both ways. Personally, I try and adjust my work hours to my client’s, and where not possible, I make sure there at least a generous overlap, so that ignorance is reduced and communication and clarity increased. Same for cultural communication differences - i make sure i understand the other side and adapt to an organisation’s predominant style, to reduce frustration. From my experience as a remote office manager, i know communication is pretty much the root of all evil.
