One would assume that this deal will get a resounding NO vote. Assuming that is the outcome, surely the next step (whilst maintaining the current CC/TB) is to continue to negotiate for a better deal for all. That includes getting rid of CoS18. That document is the end of CX as a long term employer and the end of the AoA (no need for any form of negotiations for those that join on it).
Priorities (in no particular order): Withdrawal of CoS18, pay, housing and getting rid of HKPA at some point in a career. Even those who arrive with literally nothing are eventually as qualified as the next guy. At what point that is may be debatable but eventually a HKPA recipient should be on a proper housing package.
