It seems to me that if BA think they can run an almost full program with minimum crew on each jet then they WILL wipe the rosters of all the crew that have been on strike. When news of that gets out, very few will strike next weekend IMHO.
The board's strategy is as much about culture change in BA as anything else.
Unfortunately for the individuals concerned, IMHO those who have not backed BA will not be coming back to work at BA.
