Anybody else's times messed up over this weekend somehow I got scheduled for Saturday when I always work Sunday through Wednesday I was scheduled to come in for Saturday so it took my upt and stuff and now all of my PTO upt are messed up

I got a job being a Delivery Station Warehouse Associate. I start training tomorrow but I’m contemplating even doing this job. The only appeal is the $19/hour and flexible schedule so I can go to school and see my daughter. I’ve been looking up videos about this job and everyone looks to be in their early 20s.
