I was working 48 to 60 hours a week, and never got paid over-time.

I thought she was allowed to do this, but found out two other employees called on her, and got all their overtime paid to them. And she got fined. My question is this sir, is it too late for me to do anything? I am still working for her, but can barely get 40 now. All this happened last spring and the whole year before this.
