Bit of backstory:  
So I work part time and schedules for the most part are pretty random. Sometimes you can request certain days that you want to work, and so I always request Sunday, Monday, and Friday(and almost always get them). Our schedules always come out 1-2 weeks in advance so we have time to memorize our schedules. We use the when I work app which makes you confirm your schedules before you take them. This has worked very well up until last week. I always check my schedules when I get them and then the day before my shift just to double check everything.   
When they sent out the schedules for this week (October 29- November 4) I was scheduled to only work Friday November 2 and Sunday November 4, both from 4pm-8pm. This caught me by surprise as I wasn’t scheduled for Monday as I typically am, but I confirmed them anyway. So Sunday October 28 arrives and I had a shift that evening. I checked my schedule for the next 2 weeks as I had arrived to work early. My schedule was as previously mentioned.   
Monday after school my mother had an extremely important meeting that she couldn’t miss. This meeting was from 5:00-9:30 and was half an hour away from were we live. Since I didn’t have work my mother told me I had to babysit my siblings until she got home. Everything was fine until about 5:15 when I got a text from my GM asking if I was running late to work. As I wasn’t scheduled for work I was very confused and asked if they texted the wrong person since my next shift wasn’t until Friday. They said no and sent a screenshot of the When I Work app saying I had a shift from 5-9:30. I checked the app and it asked me to confirm a shift for Monday 5-9:30. This shift had not been there less than 24 hours earlier when I had last checked. On top of that my Friday shift was changed to 5-10:30 and my Sunday shift was canceled entirely. I apologized but told the GM that I couldn’t come in as I had to babysit my siblings. They ended up working down a member, although luckily the store wasn’t too busy. AITA for not showing up?  
TL:DR   
Didn’t show up for work due to a last minute schedule change I was unaware of and had prior obligations to fulfill. Store was down a member the whole night. AITA?
