What is this conflict about?

Dr. John Wilkins sat staring at the phone message in front of him. Dr. Peter Mikelson, chief of orthopedics, had called again wanting to discuss the current system used to schedule operating room times. As chief of medicine, technically, Dr. Wilkins had the power to dictate who would use the operating resources and when. Up to now he had been reluctant to use that power, relying instead on scheduling administrators to handle the schedule for operating room use. Perhaps the time had come to review that system and implement changes if necessary.
