IWC Wage Order 16, which covers on-site construction, drilling, logging, and mining, generally requires that non-exempt workers receive an unpaid meal period of at least:

Explanation

Wage Order 16 §10(A) and Labor Code §512(a) require an unpaid, off-duty meal period of not less than 30 minutes once the work period passes five hours, and a second 30-minute meal period once it passes ten hours. The first may be waived by mutual consent only where the day's total work is not more than six hours; the second only where the first was not waived and the shift is not more than twelve. (d) and (a) are rest-period figures in meal-period clothing - 10 minutes per 4 hours is the rest rule, and neither 20 nor 15 minutes appears anywhere in California law. (c) is a paid hour, which some collective bargaining agreements do provide, but a compliant meal period is unpaid precisely because the employee is relieved of all duty.
