It's a mix of things that cause this. You're usually somewhat isolated if you're a mid to low level up/down so you have to be self sufficient in a way that smaller facilities that are clustered next to big facilities aren't.
But that self sufficiency is partly why I blame low-level up/downs for their own predicaments:
-Most places have too many positions. I'm sorry dude, but you're a five... You don't need a standalone assist, or data, or clearance, or hand-off etc. I know you can't really fix your staffing number because the FAA is stupid (and Natca gets stupid about lowering CPC counts), but getting rid of useless positions lowers your training hours and checkout times.
-A decent amount of these places are exactly the reason why the NTI exists. Working hour on hour off and sacrificing trainees. Now that you actually have to train, people fucking complain about having to do their jobs.
-Plus those places have high turnover at all their levels (flm, atm, and rep) so there is no institutional knowledge being kept, which means these problems just linger. Supes suck at TRBs. The training programs atrophy, the SOP gets outdated etc.
There are six and seven updowns that release on NCEPT regularly. If you're not one of them, then fix your facility. No one is going to come save you. Not Rich, not Nick, not JD. Learn the contract. Learn the training order. Learn the point three. Network with reps at other successful facilities. Figure out your facilty's weaknesses and help out. People shit on collaboration, but at a small place, that's all you have.
