Dear Patrick,
As per the law in your state, if you are an adult, the employer has the right to schedule however they feel they need you. There is no minimum or maximum number of hours. The employer may ask you to come in when needed, or send you home when work is slow and you are not needed.
Every employee when joins a new job is given a letter of job responsibilties(sometimes in verbal too). As a good practice your employer must have allowed you to close the store twice a week than all days in a week. Every company must follow the state labor lawss and cannot ignore it, therefore whatever rules are made in the Organisation must be made in complied with the Law whether in writing or verbal.
warm regards,
Umesh
