All open slots at facilities should be run on a bid. And if it’s hard to staff then they get move money or some other stipend. The answer is simple, but NCEPT was negotiated and therefore is better. Controllers are hard pressed to waste their time filing paperwork that means nothing other than a number on a spreadsheet for NATCA or the FAA to work off of. I get the idea behind it but some of these places are 10+ years before they’re able to release via this method.
Allowing bids on any open position, controller or supervisor, would make sure qualified candidates that want to be somewhere put their name in the hat, rather than the shotgun ERR approach NCEPT takes.
