The only way pilots will be able to keep the bastard VA management in line is for all to abide by the established policies and EBA provisions.
The only "fair" system is a in-line strict seniority system. Unfortunately with 5 types that is just to expensive to run. Every other alternative is just a work around and will end up screwing people over somewhere. The problem with the current arrangement is the ever shifting sands of what the actual rules are. People make career decisions on information at hand only to have it torn up a year later.
