Nobody knows how or when this insanity will end. If I had to guess, HK will be one of the very last places to lift restrictions and only when big brother says so. Cathay doesn't care about you, your family or your mental health. Maybe the flight decks will be empty when and if this thing turns around and maybe they will be forced to improve the contract when that happens.
For myself, they could go back to A scale and I wouldn't stay. Working for this organization is not worth it. There is far more to life than money.
