Your boss can request that you work on your "day off" and if you refuse, you can be fired. Your boss is also allowed to punish you for non-illegal reasons by cutting your hours.
By non-illegal reasons, I mean that your boss can punish you because you refused to agree to work on a particular day. But, your boss couldn't punish you because he found out you were Jewish, for example.
