I was describing what a friend of mine had to go through when he saw that he was passed over for a GS. After two days of being put on long holds by scheduling, and being told they'd call him back (they didn't), he finally got an answer that informed him he wasn't getting anything because someone senior to him had a GS in as well. Which seems like an answer they can give to anyone who's outside the top 15 in category.

No, doesn't sound like a job for a ALPA rep....maybe someone on the staff who doesn't fly and has an ALPA retirement, but more likely you just have to live with it.
