40*S,
I understand your point (thought), however, I recall our DFO clearly expressing to us, when the CPU was formed and asking us to consider joining, that CX would not accept them as a body of representation (not his exact words), and that CX would negotiate and deal solely with the AOA.
Now having said that, imagine if say 70% or greater decided to now join the CPU - would the Company change its mind or would they be going through Hong Kong's legal system to get things done?
