I worked for SkyWest over 10 years ago as a ground worker. I can’t even remember what they called their fake union (wouldn’t have been SkyWest Inflight Association) but yeah. We also had some “you don’t need a union, they’re bad” propaganda as part of our training.
Honestly, it was a pretty fun job as a college student but some of that stuff made me feel a little dirty
Edit: memory remembered SAFA, and Google says that stands for SkyWest Airlines Frontline Association. In hindsight, yeah, pretty bad.
