Am I getting screwed?

So I got a job this year working at a kindergarten. The first half of my day is spent working in the office, answering phones, emails, talking to parents and potential new customers etc. The second half of my day I help with the daycare.

My base salary is 200,000 for 7.5 hours and 30 minute unpaid break 5 days a week. I get an extra 1500 for any time spent in the daycare and any regular overtime is 1500, daycare overtime is 3000. I also get about 8 weeks of paid vacation per year.

But during the day, the 30 minute unpaid break is the only break I get. Even if I work a 11 hour shift.

Am I getting screwed? Is the contract enforceable if illegal? I'm used to 15 minute paid breaks every 4 hours and unpaid 30 minute lunch is over 5 hours.
