A panel discussion in which hypothetical situations are commented upon. The issues presented include the timeliness with which CBA procedural requirements are first raised; fairness in the allocating of hearing time; whether the arbitrator can deny a request by one party to file a written closing argument; whether, under the applicable codes of professional conduct, the arbitrator can permit non-parties to observe absent the consent of both parties; and the appropriate response to a grievant engaging in private conversation with his advocate during a break in his/her testimony.
