Personally, if I send an email to someone and they call me, that makes me suspicious of what theyre going to say. Why don’t they want to send an email back? What do they not want a paper trail of?

If someone (especially management) at my job asks me to do something, I always tell them to send me an email (via company email) telling me what they want specifically. This way, in case anyone in the future has a problem, I can reference the email and who sent it to me.I also will always respond when I complete the task so that I can reference how long the task took me to complete. As you can imagine this means I do nearly no meaningless or legally questionable tasks.

Naturally, I have done this in my personal life as well. Any conversation I feel is very important, I send a text or even an email. I once had someone respond by phone only, and this person was verbally abusive. I politely told them that any further correspondence must be done by text or email. Sadly, they never apologized, and have never spoken to me since.

So is it rude? I think it depends on the context and the person.
