BA are shooting themselves clean through the foot with the proposals as they stand. If passed in anything like the current form, or if we are all moved to the ludicrously-named and wholly nominal BARP, the meanest DC scheme in the major airline industry, then they are going to find, longer term, they lack pilots to fly the aircraft with.
It has become an utterly hostile, sinister place to work with new entrants facing a static promotion structure, outright management hostility, low morale, and crippling workloads {900 hours a year on an A320 through LHR for a thirty five year career - you'll be dead long before you retire}. Those nearing 55 now are already understood to be in a loose pact to resign if things get too bad to secure their accrued benefits. With our ludicrous crewing arrangements that alone will leave the flying programme shot to the proverbial. New entrants will be thinking long and hard about staying with BA too. The squeeze will come at them from both ends.
BA is in need of root and branch reform at management level - the recent senior resignations being but the tip of the iceburg of a culture of cynicism and contempt. They can afford far more than they claim in the pensions arena and its about time they faced reality and, as a first step, ended the culture of lies and spin that is endemic throughout senior management.
