I have a really helpful, great boss,let's call him Peter and I have always had a great relationship with him and his brother, let's call him Paul whom I also work with. Recently, my boss's brother, Paul asked me if I could help him with conducting interviews for him. As he did not cc his brother, Peter, and Paul works at a different office, I told Peter, and asked him if he wanted me to do it. My boss, Peter got mad at his brother, Paul as he didn't want me to do it, and was not happy that his brother had asked me to do his interviews, without checking with him. When I let Paul know that I couldn't do it as I had my own interviews to do, he was very understanding. But...my boss clearly had a talk with him as after that whenever I emailed Paul, he didn't respond to any of my emails. Just a couple of days ago, we were supposed to work on something together but after a week, Paul finally responded letting me know that he wouldn't be able to, and cc'd his brother on it.
Did I do something wrong? How can I fix things with my boss's brother, Paul who seems to be mad at me? Paul used to be my go to whenever I had any questions, he would help me, and I would do the same whenever he had any questions. Would appreciate your advice. Thank you!
