Disrespectful, no. Annoying af on a personal level, yes. If I email, it’s because I have time for that not your stupid rambling stories, I want a paper trail, and I don’t want to deal with people in conversation. I blatantly do not answer calls at work when I am emailing someone and if they ask if they can call, I tell them no and to please use email.
I can understand them calling in your case. I wouldn’t like it, but sometimes it’s just faster to talk things out. So long as you don’t get a rambler.
