If I recall my employment law class correctly, just being salaried is not enough to make you exempt from overtime. Of course this probably differs state to state.

If an employee does not meet even one of the criteria, he or she is not exempt (non-exempt) from the provisions of the law.....
Exempt Professional Employees are those employed in a bona fide professional capacity
whose primary work requires knowledge of an advanced type in a field of science or learning customarily acquired through a prolonged course of intellectual instruction and study, as distinguished from a general academic education and from training in the performance of routine mental, manual or physical processes;
and/or work that is original and creative in character in a recognized field;
and whose work requires discretion or judgment in its performance; and work which is predominantly intellectual and varied in character and is of such character that the output produced cannot be standardized in relation to a given period of time;
and who does not devote more than 20% of his time to nonexempt activities;
and who is compensated at the rate of $1,150 a month.
