Unfortunately, from what you write, you will probably not qualify for  overtime.1) Companies have a right to make you work as many hours as they like, subject only to the obligation to pay you overtime IF you are a non-exempt (e.g. hourly) employee--if you are exempt (e.g. many or most salaried staff), you don't even get the extra pay.2) Unless you had a written employment agreement or the like from the company delineating your hours, an employer may change or add to employee hours at will.Therefore, you company is not doing anything wrong which would justify (legally) quitting and let you collect unemployment. Also:3) Many jobs are stressful--if people could quit jobs because of stress and collect unemployment, near everyone would at some time or another. Job stress is not something, however, which you are legally protected from or which companies can't impose on you; therefore, if fyou quit for this reason, it is your own voluntary choice, but voluntary separation from a job does not make you eligible for unemployment.
