I guess sacking indiscriminately any strikers it would be counterproductive
It all depends whether the sacking was indeed indiscriminate. Sacking the first 100 who fail to turn up for work would probably scare the living daylights out of the majority of workers. Especially if you are a long time crew member with out of date qualifications for a job outside aviation. Gaining an entry level job in any industry with a take home pay similar to that enjoyed by long time BA CC would be very hard to secure in the current economic climate.
