I think this bears reading one more time. From the arbitrators...
"There simply is no fair and equitable basis for this Board to award what the CAL Committee proposes. Under the guise of protecting pilots from displacement from “then-current positions”, it would extend such protection to pilots who don’t actually have such positions at all. In short, if granted, it would interfere with the fair operation of the ISL forever by placing CAL pilots immovably in positions that their ISL seniority would not entitle them to hold."
...in other words, if you are not in training, you will not be afforded protections.
