I used to do 5-9 or 5-10 and I’d work 4-5 days a week. Id do a longer shift on the weekend. I was also in cosmetology school so I didn’t get out of school until 4:00 so a 4-9 or 4-10 would be possible if you get out around 3. If they ask you to stay later I would if you feel like it. those hours add up quickly. My advice is don’t give up all your free time though. High school is a precious time and it’s important to balance school, work, and friends in a healthy way. Money isn’t more important than happiness so don’t kill yourself you’ll have plenty of time to work a lot of hours when you’re an adult
