I have been working remotely for a couple of years now, for people I have mostly never stood beside, and I want to record what it actually requires, because I suspect more of the world is heading this way than currently believes it.
The first myth is that remote work is about freedom. It is not. It is about structure, and specifically the structure you have to build yourself, because none of the scaffolding an office quietly provides is there.
An office gives you a start time, an end time, and a hundred small social cues that tell you how you are doing. Remove them and you get two failure modes, and I have visited both. You either drift, and do very little, and feel guilty about it all day. Or you never stop, because there is no moment when the building empties and tells you to go home, and you find yourself answering something at eleven at night with a plate of cold food beside you.
The second thing it asks for is writing. I have said this before and I expect I will keep saying it. Remotely, your thinking has to survive being read by a tired person in another time zone, with no tone of voice to rescue it. Charm does not travel. Clarity does.
The third is that the work becomes the only evidence of you. Nobody can see you being busy. Nobody sees you stay late. All they see is what arrives, and whether it arrived when you said it would. There is a plain fairness in that which I have come to like more than I expected.
If the world ever had to do this all at once, it would be a shock. Most would try to rebuild the office through a webcam, and I think they would struggle, because the office was never really the point.
