How do I keep from getting burnt out at work this summer?

I work in an assisted living home part time right now because I'm still in school. However, I plan on working there full time this coming summer to save money for next year. The thing is that I'm afraid of being pressured, harrassed, etc. into working a lot of overtime because I have seen this happen to my co-workers time and time again. I don't want to work more than 40 hours a week because I want free time to myself and to see my friends and boyfriend. This is my last summer before college. Any suggestions?How do I keep from getting burnt out at work this summer?
