Depends on the HR (E)TL..
I've had one that would mark someone rehireable as long as they worked the last day. Another that wouldn’t let anyone post any shifts, they all had to be worked by the TM, to be rehireable. still yet another that lies thru her caps and told everyone they would be rehireable but half of them weren’t and it was just a stupid popularity contest with her. God I still hate her even tho she’s been gone over 3 years. And another who was a bleeding heart and would talk to the person quitting about why they leaving and almost everyone was rehireable whether they worked at all or not.
TL/dr: there aren’t any rules Peres, more like guidelines
