Variable Load. The list reference you provide in no way is intended as a substitute for long established bi-lateral industrial agreements.
Agreements right now that are being wholly disregarded by one party. That is precisely why the pilots have balloted for strike action. What other possible response could management expect after sticking two fingers up to the industrial agreement.
At the end of the day, failure to honour these agreements leaves a state of anarchy.
Whilst I realise management sieze the opportunity to cull those pilots they consider undesirable, the net effect is a serious degradation in ongoing safety of the flight operation. Good luck with that!
