Wind-up alert EK guys. Just ignore it please.
As you might expect from one individual whom has never worked for an air carrier that have/has used this technique for crew rostering.
Having said this, once EK finds out (and, I expect they will, eventually

) that the shared type of roster works well for all concerned, they will implement it anyway...perhaps in a way that is totally obtuse, in order to obtain reasonable utility from crew members.

IE: never underestimate the ability of an airline management to utilise a crew rostering technique that suits
them, not crew members.
Doubt?
Wait and see.
