I remember, before I was hired, that the company was assigning seniority per new hire class in reverse of what it should've been per the contract. According to the DALPA guy talking to us he said that it was a new hire pilot that figured it out and pointed it out and a correction had to be made. He used that as an example as to why regular pilots should always review the contract and point out things they see as wrong.
I'll always remember that story as people tell us to back down.
