Availability Change
I'm asking because this is my first job and I'm still trying to figure out how this works. So, for context, I graduated high school last year and I'm not a college student, my college is great in letting me flexible as I'm a full time student but I only go to school for 2 days, which is great because I need the money (my parents are dead, my mom passed in my junior year, and my dad passed while I was in second grade, so I've been working to get money to live off of by myself for 3 years now). Anyways, that just context of why I'm stupid, not know all this work stuff, and why I need my availability changed.
I had my availability set for two days, and now I'm going to school on two different days now for the Summer, so I'm trying to set up my new availability. I sent it in on Thursday, last week, right before my break. My HR only works on Weekdays so I knew she saw it, and I wanted to make sure she got it incase I did it wrong, because she wants us to do all our requests online and not on paper. So when I went on my lunch I asked her if she got it and she's goes, "Oh.., yeah, I got it, you know...", and that was it. I then didn't have work on Friday so I couldn't ask what she meant because I realized that her tone was weird about it, so as I was working the weekend, thinking about it , I was wondering if I should go talk to her and ask her about it if it still isn't approved when I work next, because I work on Thursday this week.
So really, my question is if I need to ask her if I need to show proof of my school dates before she approves it, or just in general why she hasn't approved it, or do I wait until the date I set the change which is the 13th?
