What work looks like
What does it look like when someone’s working?
Sitting at a desk?
Reading a book?
Talking to a co-worker?
Squinting at a spreadsheet?
Moving physical objects?
Staring out a window?
Answering the phone?
Replying to an email?
Any one of these tasks could be actual work. But not necessarily. The point is, sometimes the important work doesn’t really look like work. And sometimes busy-looking people aren’t actually working.
