I know KA staff were only fighting for what was promised to them, however please appreciate that this major win comes almost entirely at the expense of CX staff - especially pilots and their families. You seriously can't expect CX staff to be jumping for joy about this.
A quick calculation on FOC tickets. 3000 KA staff, 1-3 dependants each (say average of 2), times 4 FOC sectors per year. Equals 36000 FOC tickets per year. That will have serious adverse consequences for many, many people.
