Do I have a case if I work for an affordable housing which I feel violates a labor law?

I worked for 1 year and 2 months with the company. There is an assistant manager, manager and 1 leasing agent, but there is supposed to be 2 leasing agents. Since 2016 of December until now, the company has not hired anyone. I have been overworked, underpaid and exhausted. Over the time frame, the company hired 2 temps who were there for no more than 3 weeks.
