Have you ever had to work with a difficult colleague? How did you handle that situation?

"In my current job, I am paired in a small office with a colleague that can be rather difficult at times. We handle a lot of work over the phone and he can be very loud and boisterous at times. On top of that, he can tend to get very upset following certain phone calls with clients. When first hired and paired in an office with him, I was taken aback by his behavior and remained quiet. One day, at the advice of our manager, I simply talked to my colleague and told him that I would be very thankful if he could tone his voice down in our office and to try and use more healthy ways of handling anger on the job. In the end, this was an approach I should've used right away as he thanked me for the feedback and told me that his old officemate was the same as him regarding how they handled frustration. With him knowing that I didn't care for that approach, he vowed to be better moving forward and things are great to this day."
