I hear the jokes and the bitterness, but one has to be careful about calling some one a "scab" who isn't currently one.
My issue is this, UAL/CAL management aren't a bunch of fools, like the MECs, who are telling people to be ready for a strike in 2012 management will make plans to fly through a strike. If this "Captain" qualification and flying of CAL F/O seniority instructors is something new then one has to assume they, management, are planning for the future. They will push every limit until pushed back effectively including building up a bunch of potential strike breakers.
However isn't it sad, all Jeff and Company had to do was treat with respect and honor all UAL/CAL employees and lead them into the biggest and best airline in the world. Alas more of the same management style which began with Lorenzo and his disciples.
