Apple has by far the most flexible scheduling ever. Should you work part-time, you have complete control over what days you work. In the summer, I open my availability, but as the school semester begins, I can inform my managers of such and we make a new schedule that allows for me to be academic; they will understand.
Apple prides itself on having a work-life balance. Don’t expect a call or text on your time off. When you’re off the clock, you’re off the clock. The downside for me was working sometimes late nights and weekends. It is retail, so Friday - Sunday are the busiest days. If you’re unavailable to work those days, it’s not the right job for you. Not saying you’ll work every day of every weekend, but expect to work 2 weekend days a week pretty regularly.
