The following involved an exceptionally serious issue with a senior professor.
The Confrontation
The professor who was originally from overseas was very competent and knowledgeable and had a doctorate from an Ivy League university. The problem was that he would leave a week before the end of the semester and return a week after the beginning of the new term. These two periods were critical ones: during the last week students often needed to see their instructor regarding grades, makeup examinations, and other matters. And during the first week of the new semester students often needed to change their courses since some are oversubscribed while others are dropped. Also, his behavior was resented by the rest of the faculty who were more responsible.
The situation had existed for several years and apparently the chairpersons had looked the other way but I would not condone his behavior. I summoned him to my office and made it clear in no uncertain terms that like the rest of the faculty he was expected to be on campus during those times. He said he would comply, although he was clearly unhappy and sullen when he left.
The next day he barged into my office in a rage shouting that I was discriminating against him, pounding my desk with his fist as he circled it and kept yelling at me. In turn I yelled at him but tried to keep my cool. I thought I was going to be punched out but the conflict remained at the yelling stage. The confrontation lasted probably no more than five minutes, although it seemed like an eternity. He finally stormed out. It must have been an interesting break in the office staff’s workday. But two things happened. First, he always remained until the end of the semester and returned on time for the new one. The second thing was that we became good friends.
