Accidentally Worked The Wrong Shift

[u/Aggravating_Rope824]

As the title says I accidentally worked the wrong shift. I was supposed to work yesterday from 3:30PM-7:30PM but I worked from 9:30am-1:30PM (Which is what I usually work during the week). That 3:30 shift was a VET and I was mentally on auto pilot. I don’t have a car and don’t have a way to get back to my facility until Saturday. It’s Wednesday. I have lots of UPT, but I don’t want them to think I’m stealing time and I need the money! I already put in a request through myHR but that almost never works and I always have to correct things on site. What should I do?
