I still have no idea how she even landed the job, isn't there supposed to be an entire interview process. If I could just show up somewhere and be employed I'd have done it by now.
It reminds me a bit of the job application process in the Persona series. You pick up an application, make a call to the manager, and if your stats are high enough*, you can start work immediately, and work whenever you like; you're free to quit** whenever you're done with the social link and don't need money/stat points. As much as I enjoy those games, I know that part-time jobs don't work that way.
*Depending on the game, this can be easy or very difficult; for example, the tutoring job in Persona 4 requires maxed out Understanding, making the Tower Social Link difficult to start.
**That said, in Persona 4's Tower Social Link, the boy you're tutoring tells you he doesn't need your services anymore at the end of the social link, so there's a justification for why you don't need to show up to work any longer.
