With BA knowing in advance of any new strike the names of those who went on strike last time, should strike dates be called then all BA has to do is not roster those known CC during the strike dates. Given the relatively low percentage of strking CC compared to non-striking CC that BA has available (including VCCs and MF) then for the few days of any strike action BA would have no trouble whatsoever having sufficient staff to be able to roster known non-strikers during that time and, hey presto, all schedules will fly 100%.
Having already telegraphed to BA who is going to strike, the effectiveness of the Union's strike action and even more so its so-called "guerilla tactics" are pretty much negated.
That's assuming the Union decides to stick its neck out and risk a potentially unprotected strke call in the first place.
It's going to be interesting to see the fumbling, guffling, pathetic bravado of an excuse that the Union comes up with in two week's time when it chooses (yet again) not to call a strike. It'll probably be along the same lines as with TW last time where he stated talks with BA were at an advanced stage and didn't want to upset them - only for BASSA to reject the outcome anyway!
