Strikers will be sacked, but, of course, the real troublemakers will not have gone on strike. They will be on leave, or off sick, or skulking down route, leaving the poor cannon fodder to take the rap.
But does the ballot and notice period not give BA time to ensure thatknown troublemakers are rostered to report for new trips early in possible strike periods? And to deny new requests for lengthy spells of leave around that time?
Real sickness cannot, of course be controlled, but should be capable of being verified.
