411A - Sad fact is, most pilots know very little about the operation of an airline and the management actions that are accepted by shareholders.
T5 will calm down and work reasonably well in a few weeks.
If WW can show that the pilots (BALPA) are being unreasonable with their demands, shareholders will give the affirmative nod to management.
The shareholders can affirmatively nod to BA management until their collective heads fall off - the fact remains that a sufficiently unified labour force prepared to strike over the issue will render its implementation untenable.
The shareholders are irrelevant and don't enter into the equation, they're simply along for the ride with the controlling factor being the willingness (or unwillingness) of the pilots to strike.
