Why vote for it?
Let me be devil's advocate for a moment. The reason why this deal may be endorsed or voted for is that it helps maintain AOA input into certain decisions affecting the majority of our members. A payrise is a payrise. Why reject money offered just because it wasn't what you were expecting or feel you are worth? Better to have worked with CX in implementing inevitable actions (such as DEFO and RA65) so that, as much as possible, we can ameliorate the damage to career earnings.
There was and is a lot of effort going in on your behalf. Some GC members are more pragmatic than others and as much as they don't like the deal they think that the alternative of rejecting it is not in the membership's best interests. I have true respect and understanding for those on the GC that hold opposite views to me. It was the same in 2001. Thats democracy for you.
I am less pragmatic than my colleagues I guess!
