You can choose to answer the call or not, and the person calling should be okay with that. If they want you to call back they should tell what it’s about.

But getting mad at people for not asking to call as a blanket response is madness. (I’m not saying that’s what you’re doing, BTW.) Sometimes you can solve things with synchronous communication much faster than you could messaging.

This is how I learned about this site and one of my team has it as his status after I told him about it. Which is kinda annoying as it's always there in group chats. I have taken to just ignore hi and wait till I get an actual question

This is beautiful

Holy shit this is amazing.

Next communication rule: Start every question with "May I ask a question?" before asking the relevant question after the acknowledgment.

Or in verbal discussions, never think before you speak and to avoid anyone else speaking make a humming noise with slightly opened mouth emitting an "Uhhhmmmmmm" while you think.

I mean, as long as you follow it up with whatever you want

Hey there...

It's a common Indian thing to type a greeting, then wait for a response before actually getting to the point. It drives a lot of people crazy, because now we have to respond back and prompt them to tell us what they need and wait for a response, which is frequently a while later, causing a lot of interruption to what might otherwise be productive working time.

It turns a "can you send me this info" 5 minute task into a multiple interruption pain in the ass

You're never just on chat. You're always doing something else. The constant distraction and context switching is mentally expensive.

...so do both?

"Hi, coworker! How's your day? Anyway bossman is on me about the TPS reports, are those going to be done today?"

See? You were polite, checked in on them, AND got to the point all at once!
