Air Profit,
you mean like the reserve call out to YVR and return with min rest (16hrs) in YVR because someone in YVR went sick!!!! Not even being afforded a proper sleep opportunity on your home base local time because it is deemed as a roster disruption.
It is a fact that those of us based in HKG are getting sick and tired of PXing and PTing around the world to cover for sicknesses on a base. Trust me there are 50 guys in HKG willing to trade positions with you, so don't even think about comparing your YVR roster to a HKG roster.
