What to do when problems arise
Some people avoid addressing a real or potential conflict because they are afraid of being seen as hurtful, selfish, or rude. But addressing conflicts straightforwardly -- with an even temper, a respect for the other person's point of view, and a willingness to find a mutually acceptable solution -- is generally a sign of maturity and the best path towards improving your roommate relationships. If you need help resolving a conflict, or would like strategies for resolving differences, here are some resources and ideas that have proved successful in the past:
Step #1: Talk early. If you are concerned about a roommate's behavior or habits, don't ignore it until it becomes too stressful. See the Roommate Resource #2: Addressing a Roommate Conflict (link) for suggestions. Conflicts that go unaddressed sometimes lead to resentment or hurt feelings that become worse over time.
Step #2: Call a room meeting, with all roommates invited. Be aware and open to the possibility that roommates may have other concerns or different perceptions of your own concerns.
Step #3: Create a room "contract" or "agreement" between roommates that establishes ground rules and expectations. You can do this informally, or you can ask a RCA, your DSL, or a McCosh counselor to help you produce a facilitated agreement. See Roommate Resource #3: Creating a Roommate Agreement here. (link)
Step #4: Talk with your RCA. Ask him/her to mediate a conversation with your roommate/s about the perceived problems.
Step #5: You can also make an appointment with the university ombudsman (a professional mediator) who will talk with each roommate in turn, and then help to negotiate a happy compromise.
Step # 6: Make an appointment with your Director of Student Life, to discuss the matter.
