Sadly, short of a destructive strike, there is very little we can do that will change the past 20 years of attack against the staff, which will undoubtedly continue well into the future (the present setback in their plans will only prove a temporary reprieve). Ultimately, the only real power you have is to either band together and shut down the operation, or more realistically, resign and take your skills, dedication and loyalty somewhere that will prove more appreciative of those character traits (those companies do exist, look at Southwest in the US). There is no future here as an expat airline pilot. The body is just twitching, but it is dead. Sadly, many will still waste precious years hoping it will get better, but in fact it only ever gets worse (look at the recent negative changes to the 777 rosters). There is an institutionalized mindset that emphasis's power at any cost, even if it eventually collapses the airline. They would prefer that outcome, so as to not set an example to their other Swire workforces that employee resistance would be effective.
Accept that CX was a bad career choice, and make firm plans to salvage the rest of your career potential elsewhere. There is only misery ahead for CX pilots. The likes of RH and his bloodyminded Swire brothers will ensure that. To them it is short term power and bonuses, as they will move on to their next Swire posting. The long term fate of CX really doesn't concern them, and certainly your particular concerns and needs don't. Get out while the industry is providing other options. All too soon those doors will close.
