CX management cannot dictate who they will talk to and who they won't. If the AOA chooses to use professionals and the message is from the membership then CX can hardly ignore this. Do you really think the company position is decided by those at CX City ? Their entire strategy is being planned by professionals in New York or London and the message is being delivered by the mouth pieces here in HKG.
The AOA could do exactly the same. Keep the professionals away from the actual meetings but say and do exactly as they say during the face to face meetings.
This isn't rocket science it's how business is conducted in the 21st century.
