How long is the orientation really? I work nights an I work the night before while also doing another job on top of that with farmwork and dogsitting so that'll have me up until at least 10am then I have to grab a couple hours before the orientation. I already have my schedule, ID, and did the bookstore trip. I'm just wondering if I will have to be there until 6pm or if I'd be able to go late and what I might miss if I did?
