I'm gonna wait for the Q&A before getting spun up but yeah, the language about selecting a ZTL in leu of a furlough is concerning. Not sure why it couldn't just be written to release a furlough number, ZTLs are awarded, the furlough number is reduced by those taking a ZTL not inside the original furlough footprint, then furlough based on the new number (including anyone that was awarded a ZTL if they fall inside).
I don't speak legalese however, so I'll see what the union says.
