Some guesses:
A slight payrise, ... maybe 2% for the next 2 or 3 years. Not for all of course!
A slight increase in the HKPA.
CX will hope that these sweeteners will offset:
88 hour threshold
Continuation of the imposed RPs
Continuation of the sickness intimidation program
Removal of Training Ban for next X years.
The requirement to call CC at some time before duty start.
Removal of contract compliance with an assurance to not use it again for X years.
