The shift schedule is Juni's department - if there's a particular shift you want, let her know (or post it here; she should see it). If you don't have a particular one in mind, the fact that you've posted here means she'll include you in the next cycle (or possibly add you for the current cycle; I'm not sure just how she handles that).

Ah! Why didn't someone say so?!

I think I would like the Third Shift (Day Three) because the number three feels like it would be the best.
