No doubt, if the mainlanders walk then the AACS boys will become very busy. And in case of a sustained work stoppage, there'll be vacancies to fill at AACS. Especially left seat vacancies which would provide irresistible opportunities for prospective mainlander scabs.
Something was learned from the group dynamics of the ComAir pilots: A strike which had lasted several months without producing one (non management) scab! It was the "tightest" pilot group on record. Will the Atlas pilots be this strong and determined?
There are no desperate situations, only desperate people.
