Having difficult conversations

I'm posting this question to find out more about how others navigate difficult conversations. I wasn't trained in any of my jobs on how to have hard or difficult conversations. Eventually I got training but I had to take a course on my own.

I'm curious, does your company train on having difficult conversations and how to handle them?

or did you have to pay for your own training like I did?

If you did get any training on handling difficult conversations, what did you find the most useful?
