To quote the letter you posted:
Management insist any deal must deliver items including an open ended AAVA agreement and MET provision. Our views as to the value of these items differ significantly.
In other words, show us a decent amount of cash and we'll consider it.
Am I wrong or is that what ATSAs have done consistently since VR was offered? As far as I see it, the ATCOs branch have done nothing to the detriment of their PCS colleagues. If they had, the NTUS would have disbanded.
Your comments are therefore spurious.
