I'd pay for a slack add-on that gave my folks "message tokens". If they used a token it would send a message to me and then, as soon as I replied, if would open a 3 minute window for us to correspond. Then the window would close and the convo would be over. 3 tokens per day per employee. would cut down on the annoying stuff.

Or, as suggested above, make it look less chatty, add mandatory subject lines.

Thinking up a subject alone focusses the mind.
