Legal Question in Employment Law in California

First off, you say she is getting weekends off, so it is not true that she is not getting days off of any kind. In fact, however, if the employer is willing to pay the overtime required, they can actually give no days off at all. They certainly are not required by law to give any holidays off - only to pay overtime on certain national holidays.

Legal? Yes, she can be required to work seven days per week, as long as she is properly paid all time and OT worked. She is entitled to, and required to take, breaks and lunch per the Labor Code, and to monetary penalties if they are denied.
