The only way to stop this suicidal trend is the re-introduction of Unions
I've espoused this for decades ever since Lord King of BA back in the 70s....even though trade unionism in the UK was overrun with commies and socialists with their own political agendas back then and needed a severe boot up the kyber.
As one old pilot in my youth once told me, employers will pull you out of your Hilton on an overnight and put you back upstairs in the hangar given the chance. You'll be worked to death and your pay gradually but continuously cut UNLESS YOU BELONG TO A STRONG UNION. Low cost carriers, an industry disease in my book, are at the forefront of indirectly reducing T&Cs of the real airlines as the corporate levels seek to match or come close to the 'low-cost' fare regimen.
However any Union must be moderate with no political agenda nor aligned to any Union umbrella (TUC / ACTU for example).
