No, that does not make you eligible for unemployment insurance. Employers have the right to make you work as many hours as they like, or to define a job as involving 50, 60, 70, 80, or more hours, subject only to--if you are hourly--paying you for all hours worked and for overtime when you work more than 40 hours in a week. If you can't or choose not to work that many hours and leave, that is a voluntary resignation and you are ineligile for UI.
