This whole argument that "we are giving company a chance to recruit more aussies" is idiotic.
Nothing in the CBA prevents them from opening the XXX gateway with a $1250 cap tomorrow unilaterally. This LOA does not change anything in their ability to do so. So if that is your concern, well, you're just misinformed.
So, we get better retirement, and give nothing back. If people keep voting with their feet, they will come back to offer more.
Easy yes.
