Alvarado v. Dart Container Corp. of California
To calculate overtime, a flat-sum bonus’s per-hour value is found by dividing the bonus only by the employee’s nonovertime (regular) hours — not total hours — making California’s method more employee-favorable than the federal rule.

Flat-Sum Bonus
Reversed
In brief. The Court decided how a flat-sum bonus factors into the overtime “regular rate of pay.” It held that “a flat sum bonus must be treated as if it were earned on a per-hour basis throughout the relevant pay period,” and that, because such a bonus is earned for working the assigned (nonovertime) hours, “only nonovertime hours should be considered when calculating the bonus’s per-hour value.” (Alvarado v. Dart Container Corp. of California (2018) 4 Cal.5th 542, 554–555.) Dividing by nonovertime hours alone yields a higher overtime rate than the federal practice of dividing by all hours worked. (Id. at pp. 554–567.)
Facts
Hector Alvarado worked for Dart Container Corporation. (4 Cal.5th at pp. 547–548.) Dart paid an “attendance bonus” — a flat sum for employees who completed a full assigned weekend shift, regardless of how many hours the shift entailed. (Ibid.) When an employee earned the bonus and also worked overtime in the same pay period, the bonus had to be folded into the “regular rate of pay” used to compute the overtime premium. (Ibid.) Alvarado contended Dart used the wrong divisor — spreading the bonus across all hours worked (including overtime) rather than across nonovertime hours — thereby understating his overtime pay. (Id. at pp. 548–549.)
Procedural history
The trial court granted Dart summary judgment, and the Court of Appeal affirmed, applying the federal Fair Labor Standards Act method (dividing the bonus by total hours, including overtime). (4 Cal.5th at pp. 549–550.) The Supreme Court granted review and reversed, adopting the more employee-favorable nonovertime-hours divisor under California law and holding the decision applies retroactively. (Id. at pp. 550, 567–574.)
Issue
When an employee earns a flat-sum bonus and also works overtime in the same pay period, how is the bonus’s per-hour value calculated for purposes of the “regular rate of pay” — by dividing the bonus by all hours worked (the federal method) or only by nonovertime hours? (4 Cal.5th at pp. 546–547.)
Holding
Divide by nonovertime hours only. “[A] flat sum bonus must be treated as if it were earned on a per-hour basis throughout the relevant pay period,” and “only nonovertime hours should be considered when calculating the bonus’s per-hour value.” (4 Cal.5th at pp. 554–555.) Because “the word ‘regular’ in the phrase ‘regular rate of pay’ refers to regular time (i.e., nonovertime),” the flat-sum bonus is allocated across regular hours and then included in the regular rate, producing a higher overtime premium than the federal approach. (Id. at pp. 555–567.) The decision applies retroactively. (Id. at pp. 567–574.) Reversed. (Id. at p. 574.)
Reasoning
1. Regular rate is not the straight-time rate. The Court began with first principles: “[a]n employee’s regular rate of pay . . . is not the same as the employee’s straight time rate.” (4 Cal.5th at pp. 551–553.) The regular rate “can change from pay period to pay period” and “includes adjustments to the straight time rate, reflecting, among other things, shift differentials and . . . bonuses.” (Ibid.) A nondiscretionary flat-sum bonus must therefore be folded into the regular rate before overtime is computed. (Ibid.)
2. A flat-sum bonus must be converted to a per-hour value. Because the regular rate is an hourly figure, “a flat sum bonus must be expressed as a per-hour value if it is to be . . . factor[ed] into the regular rate.” (4 Cal.5th at pp. 553–555.) The contested question was the denominator. (Ibid.)
3. “Regular” means regular (nonovertime) hours. The Court held the divisor is nonovertime hours, reasoning that “the word ‘regular’ in the phrase ‘regular rate of pay’ refers to regular time (i.e., nonovertime).” (4 Cal.5th at pp. 555–560.) A flat-sum attendance bonus is not earned by working overtime; it is a fixed reward for showing up for the assigned (regular) shift, so its hourly value should be measured against the regular hours it compensates. (Ibid.) The Court found this reading consistent with California’s policy of construing wage laws to favor employees and discouraging overtime, and noted the result diverges from — and is more protective than — the FLSA method of dividing by all hours worked. (Id. at pp. 560–567.)
4. The DLSE manual and statutory interpretation. The Court acknowledged that the Division of Labor Standards Enforcement (DLSE) had endorsed the nonovertime-divisor approach in its enforcement manual, but that the manual provision was a “void” underground regulation never properly adopted. (4 Cal.5th at pp. 555–557.) The Court reached the same result independently, as a matter of statutory and wage-order interpretation, not deference to the manual. (Ibid.)
5. Retroactivity. The Court applied its holding retroactively. (4 Cal.5th at pp. 567–574.) Weighing reliance interests and the absence of a binding prior rule (the DLSE manual being void), it concluded the decision merely interpreted existing law and so governed conduct predating the opinion, exposing employers who had used the federal method to recalculation. (Ibid.) Chief Justice Cantil-Sakauye concurred separately. (Id. at pp. 574 et seq. (conc. opn. of Cantil-Sakauye, C.J.).)
Significance
Alvarado is the controlling California authority on incorporating flat-sum bonuses into the overtime regular rate, and a leading example of California wage law departing from — and exceeding — the federal FLSA. Its nonovertime-hours divisor increases overtime liability for employers that pay flat attendance or similar bonuses, and its retroactive application exposed past pay practices to claims. The decision is essential in wage-and-hour class and PAGA litigation involving bonuses, and it reinforces the broader principle (echoed across the California wage canon) that the state’s overtime protections are construed in employees’ favor and are not limited by federal law. It pairs with the regular-rate analysis later applied to meal and rest premiums in Ferra v. Loews Hollywood Hotel, LLC (2021) 11 Cal.5th 858. See the Review’s coverage of the wage-and-hour line.

Practice pointer
Audit flat-sum bonus overtime math. After Alvarado, employers paying flat-sum bonuses (attendance, weekend, shift, or similar fixed rewards not tied to hours or production) must compute the bonus’s per-hour value by dividing by nonovertime hours only, then include it in the regular rate — do not use the FLSA total-hours method. Plaintiff’s counsel should examine bonus structures in wage cases, since the wrong divisor systematically underpays overtime and supports class and PAGA claims, with Alvarado’s retroactivity reaching back. Distinguish flat-sum bonuses from production or percentage bonuses, which may be allocated differently. Pair the regular-rate analysis with Ferra when meal/rest premiums are also at issue.
Open questions
Alvarado expressly addressed flat-sum bonuses; how its reasoning applies to other forms of compensation — production bonuses, commissions, and percentage-of-earnings bonuses — and the precise divisor for each remains the subject of continued litigation. The interaction of California’s regular-rate rules with the FLSA in multistate payroll systems, and the scope of retroactive exposure, also continue to be worked out.
