I don't think that the outcome of this fight will have any impact on those airlines whose conditions are already appalling when compared to BA....
On the contrary. If you even have a sniff of your present T&Cs improving at the moment, specifically if there are better deals elsewhere and folks keep leaving your outfit to get them,
market forces dictate that your outfit will have to improve it's T&Cs to retain it's pilots. If the T&Cs at other outfits deteriorate to match those in your current outfit, where is the incentive for them to be improved at your outfit?
It's not rocket science.
