Hypothetical question

I work as an "Assistant Manager" at a retail chain in California making $55K salary. I regularly work 55-60 hours per week. No overtime pay because they say I'm exempt/salaried.

But most of my work is stocking shelves, running the register, and cleaning. I barely manage anyone — there are 2 part-time employees who technically report to me but I don't hire, fire, or evaluate them. My manager makes all those decisions.

Am I actually exempt from overtime?
