Why would someone walk out on the job like that?

So i heard from one of my coworkers that a girl walked out on her job because she got written up for too many call offs. This is a union job so one write up isn't gonna do much harm. I believe it takes at least 3 write ups to get fired. Anyway i heard she just walked off on the job before her shift ended. What really funny is i cheeked this girls Instagram and she is applying to another retail job i wonder how long she will last there lol. What do you think?
