What is the purpose of having to enter the RF 100 PDIS?

If you have a displacement preference and the company WILL displace you anyway, what is the point? Will they NOT look at it the displacement preference if you don’t and just get stuck somewhere with a NEB?

Alll of the correspondence from the union on this still sounds as if a qualified FO still has a choice NOT to upgrade. That hasn’t been the case since last October when a few VERY senior FOs slipped by, but they were all tagged in January. If there were not more slots than pilots, there wouldn’t be anything left for a standing vacancy.

Just sounds like double talk and the Union isn’t fully up on what is actually happening.
