I have ADHD and every interruption harms my productivity. If a co-worker emails me "hello" there are two possibilities: 1) Notifications are enabled, and visible/audible to me. If I'm working, I will likely be set back by multiple minutes by the interruption. I respond back asking what they need and it takes them a few minutes to formulate their question, at which point I've possibly managed to refocus and begin working again. There is a desperate struggle to switch context without losing the mental model I have been building of the problem at hand, before I have the chance to record it by writing some code, a comment or personal notes. 2) Notifications are disabled. I see the "hello" an hour later. I respond "hi, what's up?" and my coworker is now in a meeting or something and takes an hour to get back to me. They respond with "I was wondering if you could help me with something" and the cycle begins anew. And by the way, I actually really like helping people with technical problems. I would sit around all day doing just that if I didn't have other work to do.
