Every penny BA loses as a result of BASSA's strike action, or the threat thereof, is cash which is unavailable to the pension fund. What do you think will happen to BA's ability to fund NAPS if BASSA bleeds the company dry in this futile 'fight to the death'?
In case you haven't noticed, this is not BASSA vs Walsh, this is BASSA vs almost everyone else in BA. What on earth are you thinking?
Before responding, please look up the term 'Pyrrhic victory'.
