SLC CRJ FOs have been bypassed on transitioning to the right seat of the ERJ in SLC. It's definitely been a violation of seniority. New hires last year were saying they'd only come to work at SkyWest if they could get the ERJ. The company gave those training slots to the guys off the street so they wouldn't go work somewhere else.
The new pay package has attracted a bunch of pilots and the company is now letting some of the FOs transition. Most of them have 8+ years seniority.
