What must a guard do if they have worked for a week with no days off, specifically on the seventh day?

The requirement for guards who have worked for a week with no days off is that they should receive overtime pay for any hours worked beyond the standard 40 hours in that week, which includes the seventh day of work. Under California labor law, employees are generally entitled to overtime pay when they work more than eight hours in a single day and more than 40 hours in a workweek.

For guards, just like any other non-exempt employees, if they work on the seventh consecutive day, any hours worked on that day would qualify for overtime compensation. This is designed to ensure that workers are compensated fairly for extended hours and to encourage a reasonable work-life balance.

In this context, while some choices might suggest other actions or forms of pay, they do not reflect the legal obligation for overtime compensation for additional hours worked in a week without a break. Therefore, the correct choice emphasizes the entitlement to overtime pay on that seventh day worked.
