I don't think Willie will sack or lock out. Up until now, he has done exactly what he has threatened he would do. I think strikers will lose staff travel permanently, and that will be his only sanction. That alone will be more than enough to ensure that it is only the real militants that actually strike on the day. Once Willie sees that pretty much everyone is coming into work, he will just continue to run his airline. BASSA and the militants can then just be ignored. And once they no longer have staff travel privileges, perhaps they will just decide the job is not worth it and quit? One can always hope.
