Perception that strategic business staff needs to be physically present to deliver timely and effective financial analysis and advice. Fear of centrally-imposed, mandated details. Perception that department chairs will lose some control over their budget. Chairs have fought hard for existing resources - don't want to give them up. Perception that unit doesn't value loyalty anymore.
Some secretaries enjoy current diversity and responsibility of their positions.
Fear of demotion when responsibilities are removed. Need to prevent chairs, faculty, and others from continuing to use local secretaries and reverting back to old ways. Need to provide faculty training and equipment for email, voice mail, etc. If no secretarial consolidation, not as much secretary coverage. Fear of loss of communication and service.
