Statutory Architecture of California Labor Code Section 510
California maintains some of the most robust worker protection statutes in the United States. While federal law relies on a simple 40-hour weekly threshold under the FLSA, California employers are governed by California Labor Code Section 510 and the wage orders issued by the Industrial Welfare Commission (IWC).
Under Section 510(a), eight hours of labor constitutes a day’s work. Any work in excess of eight hours in one workday, any work in excess of 40 hours in any one workweek, and the first eight hours worked on the seventh day of work in any one workweek shall be compensated at the rate of no less than one and one-half times (1.5x) the regular rate of pay. Furthermore, any work in excess of 12 hours in one day, and any work in excess of eight hours on any seventh day of a workweek, must be compensated at no less than twice (2.0x) the regular rate of pay.
California Overtime Wage Multiplier Matrix
| Threshold Condition | Multiplier | Statutory Basis | Example ($30.00/hr Base) |
|---|---|---|---|
| Up to 8 hours in a workday | 1.0x (Regular) | CA Labor Code § 510 | $30.00 / hr |
| Over 8 hrs up to 12 hrs in a workday | 1.5x (Daily Overtime) | CA Labor Code § 510 | $45.00 / hr |
| Over 12 hours in a single workday | 2.0x (Double Time) | CA Labor Code § 510 | $60.00 / hr |
| First 8 hours on 7th consecutive day | 1.5x (7th Day OT) | CA Labor Code § 510 | $45.00 / hr |
| Over 8 hours on 7th consecutive day | 2.0x (7th Day Double) | CA Labor Code § 510 | $60.00 / hr |
How the 7th Consecutive Day Rule Functions
A widespread misconception is that working any seven days triggers the 7th day rule. Under California law, the rule applies only when an employee works on all seven consecutive days within the employer’s established 7-day workweek (such as Monday through Sunday). If an employer’s workweek runs Sunday midnight to Saturday midnight, and an employee works Wednesday through Tuesday across two different workweeks, the 7th consecutive day rule does not apply because the shifts did not occur within a single payroll workweek.
Alternative Workweek Schedules (AWS) & 4x10 Agreements
An exception to daily overtime occurs when an employer and a designated work unit adopt an Alternative Workweek Schedule (AWS) under California Labor Code § 511. Under a valid AWS (e.g., four 10-hour days per week), employees may work up to 10 hours per day without daily overtime pay. However:
- The agreement requires approval by a two-thirds secret ballot election among the affected employees.
- The results must be formally registered with the California Division of Labor Standards Enforcement (DLSE).
- Work performed beyond 10 hours in a day must still be paid at 1.5x regular pay, and work beyond 12 hours must be paid at double time (2.0x).
Meal & Rest Period Compliance (California Labor Code § 226.7 & § 512)
California law requires that employers provide an uninterrupted, off-duty meal period of not less than 30 minutes before the end of the fifth hour of work. A second 30-minute meal period must be provided before the end of the tenth hour. If an employer fails to provide an off-duty meal or rest break, the employer must pay the employee one additional hour of pay at the employee’s regular rate for each day a meal break was missed, and an additional hour for missed rest breaks.
