This should go without saying, but if anyone at your facility has ERRs in to places they could be selected for but would turn down, they're a gigantic piece of shit. It isn't as simple as 'oh he/she turned it down, it goes to the next person'. The entire NCEPT panel has already met, facility that fill all their available vacancies can't just take person X who should've been eligible. The only time I've heard of it 'working out' is if the next available person had an ERR into a place that didn't fill all of their vacancies. Not only does this potentially screw over potential co-workers, if you get selected for a facility that filled all their available vacancies, you're taking a spot away from someone who would've actually gone.
