A couple of things.
While there are a few consistent moaners it's a reflection of the larger problem. CX and recently EK seem to be two airlines that now have consistent complaints on PPrune and it not surprising that labour laws benefit the employer and not the employees for both these airlines. ("If you don't like it, leave") While all airlines have problems I don't see the likes of BA/QF etc pilots consistently complaining here.
Exit strategy, much easier if you can sell your property and have a foreign ATPL to move on and absorb the 30-70% paycut to start at the bottom of a new seniority list. Here lies the problem, many new joiners will have no quick way to a foreign ATPL and you can't afford a property to buy let alone sell, so by the time you get yourself into a position to leave you are well and truly trapped by the seniority system.
The system is designed to get you in the door and financially cripple you over time into staying.
