In the 6 years I've been working in the ramp towers at SFO, I can count on one hand how many transfers actually certified in the FAA tower. But 20+ have ended up in Oakland or other airports washing out while people keep retiring. I imagine it is the same everywhere.Yes, we are at that critical a level of staffing. In my area, we are supposed to have I think it’s 63 certified controllers for 100% staffing. By this June, we will have 27.
Meanwhile I'm just here, chillin in the hiring pool(again since they abruptly closed it last time after saying I'd be in it for 3 years). They haven't taken anyone from my pool due to backlog from 2016-2017 hires who haven't gone to OKC, I'm sure the shut down only made that much, much worse.
