Around holidays there is usually plenty of hours, a lot of time part-timers are able to work full-time.
They aren't very flexible with scheduling if you're new, which makes it a hard job to work when a student and they try to make you work during your classes. Minimum 25hrs for part-time, and if you can't work that must either switch to limited part-time, which means you are chosen last for shifts, or work student hours which are typically Friday - Sunday closing shifts (this is for the Deli, not sure what other departments have set up for students).
Set raises depending on the amount of hours you work, makes working here during the Summer worth it if you can reach the next bracket for hours worked.
Set raises at pre-specfied hours worked
