Matzpenetration assuming BALPA call the company's bluff and IAG respond by farming out S/H to Vueling or what have you, what would be the point in joining a fleet that is staring potential obliteration in the face?
Yes it may well just be a great ruse to wangle a pay cut. Many operational fixes are required such as greater use of fixed links etc etc. But all of that aside, a threat still exists, albeit there are now only 6/5/whatever sounds scarier weeks to sort it.
