You guys aren't going to the sandpit

Do your homework! Concentrate on improving the situation not running away from it.
Yes. The HKAOA leadership have failed. It was predictable because they didn't follow the rules:
1. The President should not be involved with negotiations. Failed.
2. Have a mandate and keep the GC informed or they might not support your deal. Failed.
3. Have credibility. Don't include those who lack judgment
4. Do have a lever and use it or else you will get cornered into what they want...CoS08. Failed.
5. Don't give rostering productivity (RP07) on the promise of talks on a payrise. You'll end up giving the productivity (RP07) and get just that ... "talks" on a payrise. Failed.
But most importantly; don't ever give up on fellow negotiators, Committee and 49er types who supported the cause and were unfairly terminated by management for it. You did, and as a result, you will be forever plagued by the inept and weak as your HKAOA leaders.
What to do about it? For a start, close the door on the AOA. It's not a union; you need a proper union, some smarts and plenty of resolve if you want to sort this management.
Please stop pretending that the grass is greener in Dubai; for starters, there is none.
