Regular Rate & Overtime
Daily and weekly overtime, qualifying compensation, Alvarado’s flat-sum bonus calculation and commissioned-employee exemptions.
Statutory Framework
Labor Code section 510 establishes daily and weekly overtime thresholds. Any work in excess of eight hours in one workday, or in excess of 40 hours in any one workweek, must be compensated at one and one-half times the regular rate. Work in excess of 12 hours in one day triggers double time.
The regular rate translates includable remuneration into the rate used to calculate overtime. Hourly pay, shift differentials, nondiscretionary bonuses, commissions and piece-rate compensation can affect it. The denominator and additional overtime treatment depend on the kind of payment and the period in which it was earned; a single total-pay/total-hours formula does not cover every California pay plan.
Regulatory Overlay
Section 510 and the applicable Wage Order supply the overtime framework. The general rule includes time and one-half after eight daily or forty weekly hours, double time after twelve daily hours, and seventh-day premiums within the employer’s defined workweek. Valid alternative-workweek arrangements and specific statutory or Wage Order exceptions require separate analysis; do not apply the general rule without classifying the employment first.
California and federal calculations can differ. For the flat-sum attendance bonus at issue in Alvarado v. Dart Container Corp. of California (2018) 4 Cal.5th 542, the divisor is the nonovertime hours actually worked during the relevant pay period—not just the triggering day and not all hours including overtime. The additional overtime compensation on that bonus uses the full 1.5 multiplier for time-and-one-half hours.
Case Law Framework
Alvarado v. Dart Container Corp. of California (2018) 4 Cal.5th 542 distinguishes a flat-sum bonus from compensation tied to production or hours. Its nonovertime-hours divisor and full overtime multiplier must be applied to the payment actually at issue. Calling every commission or production incentive a flat-sum bonus would overextend the holding.
Ferra v. Loews Hollywood Hotel, LLC (2021) 11 Cal.5th 858 confirmed that the regular rate calculation applies not only to overtime but also to meal and rest period premiums under section 226.7.
Defense Strategies
Discretionary bonus exclusion. Analyze whether the employer retained discretion over both the fact and amount of the payment until at or near the end of the period. An advance promise, contract or established incentive can remove the discretion required for exclusion. A payroll label alone does not decide the regular-rate treatment. (29 C.F.R. § 778.211.)
Commissioned-sales exemption. Labor Code section 204.1 is a commission-payment timing rule, not the general overtime exemption. Wage Orders 4 and 7, section 3(D), exempt qualifying commissioned employees only when earnings exceed one and one-half times the minimum wage and more than half of compensation represents commissions. Test every required condition, the relevant pay periods and the applicable Wage Order; commission pay alone does not establish exemption.
Certification methodology. Identify whether the alleged error arises from a common pay formula, a shared exclusion or genuinely different compensation arrangements. Differences in amounts alone do not defeat predominance. A useful defense connects the proposed classwide method to the records and shows precisely which liability or computation questions it cannot answer.
