UPDATE on my part time job situation:
I managed to haggle my way into getting my hours back for this week but it’s a bit hazy about what will happen in the future…
I managed to gather up confidence to ask my manager about this whole situation but she told me it’s out of her hands since she was just following the orders of the higher ups. And she’s going to be transferred to a different branch next week so I’m not sure if the new manager will give me less hours. :/

I really want to look for another part time job but I’m stuck in this current one with odd hours that won’t allow it (unless I want to skip on sleep). I guess I’ll have to look for another soon..
