"Fortunately, I have had only one difficult relationship with a colleague when I was first starting my career. I handled it by recognizing there was an issue and asking my colleague to speak in private. I calmly asked him if I had done something wrong because I felt like he was always trying to avoid me. It turns out there was a misunderstanding in our respective job duties, and my colleague thought I was trying to undermine his position by doing his work. I did not realize I was doing his work and thought it was one of my responsibilities. I apologized and thanked him for speaking with me. Once we cleared up who was responsible for each job duty, we never had an issue again."
