California Court of Appeal Revives Wage and Hour Class Certification Fight Over Bonus Pay and the “Regular Rate of Pay”
California employers often understand overtime as time-and-a-half based on an employee’s hourly wage. That is a good starting point, but it is not always the whole calculation.
In Martinez v. Sierra Lifestar, Inc., filed April 21, 2026, the California Court of Appeal, Fifth Appellate District, addressed a recurring wage and hour issue: when employees receive bonuses, how must those bonuses be included in the “regular rate of pay” used to calculate overtime, double time, and meal and rest period premium pay? The case did not decide whether the employer ultimately violated the Labor Code. Instead, the appellate court decided whether the trial court used the correct legal analysis when it denied class action certification. It concluded the trial court made a legal error and sent the case back for further proceedings.
The Employer, the Employees, and the Bonus Pay Issue
Sierra Lifestar, Inc., doing business as Lifestar Ambulance, provides 911 emergency ambulance services in Tulare County. The company employs paramedics, emergency medical technicians, clerical employees, and an IT technician. The plaintiff, Adam Martinez, worked as an EMT for Lifestar for about 10 months, from September 2019 to July 2020.
In May 2020, Martinez received what Lifestar called an “EMS Bonus.” The bonus was tied to National Emergency Medical Services Week, which Lifestar’s vice president described as an annual opportunity to recognize paramedics and EMTs for difficult work. According to the evidence discussed by the court, Lifestar gave employees something for EMS Week, such as food, gift cards, equipment, or other items. In 2020, Martinez received a separate bonus payment grossed up so he would net $100.
Martinez alleged Lifestar failed to include bonuses when calculating employees’ regular rate of pay. That alleged omission mattered because the regular rate is used to calculate overtime, double time, and premium pay owed when legally required meal, rest, or recovery periods are not provided. The Court of Appeal noted California follows the federal Fair Labor Standards Act definition of regular rate, and the regular rate generally includes nondiscretionary forms of compensation, not merely the employee’s base hourly wage.
The Class Action Allegations
Martinez filed a class action complaint in July 2023. His operative complaint alleged several wage and hour claims, including failure to pay minimum wages and overtime, failure to provide meal and rest periods, failure to timely pay final wages, inaccurate wage statements, unfair business practices, and PAGA penalties.
For purposes of class certification, Martinez focused on a “regular rate” theory. He sought to certify a class of current and former hourly employees who received one or more bonuses Lifestar allegedly excluded from the regular rate calculation. The case involved 10 bonus categories in Lifestar’s payroll data, including “Bonus,” “Clerical Bonus,” “EMS Bonus,” “Lead Bonus,” “Manager Bonus,” “Paramedic Bonus,” “Preceptor EMT Bonus,” “Preceptor Paramedic Bonus,” “Recruitment Bonus,” and “Sign-On Bonus.”
Martinez’s expert reviewed payroll data for 135 employees covering pay periods from July 2019 through November 2024. The expert identified 1,217 employee pay periods in which a bonus was paid, and all of those bonus pay periods also included overtime or double time. The expert also found 1,133 of those bonus pay periods included meal premium pay.
Why the Trial Court Denied Class Certification
The trial court denied class certification based on one issue: typicality.
In class action practice, a proposed class representative must show his claims are typical of the class. The requirement does not mean the representative’s facts must be identical to every other employee’s facts. The question is whether the representative and the class members suffered the same or similar injury from the same general course of conduct.
Lifestar argued Martinez was not typical because he received only one type of bonus, the EMS Bonus, and only once. Lifestar also argued there were different bonus categories with different criteria. In Lifestar’s view, Martinez could not fairly represent employees who received other types of bonuses.
The trial court accepted that argument. It reasoned Martinez might be uniquely subject to defenses based on the nature of his EMS Bonus. In particular, the court pointed to possible exclusions from the regular rate for gifts or discretionary payments made in recognition of services. Because Martinez’s bonus was tied to EMS Week, the trial court believed Lifestar might have a unique defense against Martinez that would distract from the claims of the broader class.
The Court of Appeal’s Analysis
The Court of Appeal reversed.
The appellate court explained typicality is focused on whether the named plaintiff’s claim is sufficiently connected to the class claims. It cited the familiar test: whether other class members have the same or similar injury, whether the action is based on conduct not unique to the named plaintiff, and whether other class members were injured by the same course of conduct.
Applying that test, the court found Martinez’s claim was typical. Martinez and the proposed class members alleged the same injury: underpayment of overtime, double time, and premium pay, along with inaccurate wage statements, due to the exclusion of bonuses from the regular rate. The alleged course of conduct was also the same: Lifestar did not include bonuses when calculating the regular rate of pay.
The Court of Appeal also rejected the trial court’s “unique defense” reasoning. A unique defense can defeat typicality when it applies only to the named plaintiff or a small subset of the class in a way likely to dominate the litigation. But the defense here was not unique to Martinez. The evidence showed other employees also received EMS Bonuses, including EMS Bonuses tied to National Emergency Medical Services Week. If Lifestar argued those EMS Week bonuses were gifts or discretionary payments, that defense applied to many employees, not only Martinez.
That distinction drove the result. The Court of Appeal held the trial court misinterpreted what “unique” means in the typicality analysis. A defense is not unique merely because it applies to the named plaintiff. It must be peculiar to the named plaintiff in a way that makes him atypical. Here, Lifestar’s EMS Bonus defense was a shared defense as to multiple employees, not a one-off defense against Martinez alone.
What the Court Did Not Decide
The Court of Appeal did not order the class certified. It also did not decide whether Lifestar actually owed additional overtime, double time, meal premium, rest premium, wage statement penalties, waiting time penalties, or PAGA penalties.
Instead, the appellate court reversed the denial of certification and remanded the case to the trial court for further consideration. The trial court may still evaluate other class certification issues, including whether common questions predominate, whether the proposed class should be narrowed, or whether subclasses should be created for different bonus categories.
That procedural posture is important for employers. The decision is not a final ruling on liability. It is a ruling about how courts should analyze typicality when an employer argues the named plaintiff received only one type of bonus.
Employer Takeaways
The decision is a useful reminder that bonus pay can create regular rate exposure even when the bonus feels informal, occasional, or disconnected from ordinary hourly compensation.
Employers should not assume payroll labels control the legal analysis. Calling something a “bonus,” “gift,” “recognition payment,” or “discretionary” payment does not end the inquiry. Courts and agencies look at the substance of the payment, including whether employees had reason to expect it, whether it was tied to work performed, whether the amount was determined in advance or under a formula, and whether the employer retained true discretion over both the fact and amount of payment.
The case also shows how payroll practices can become classwide evidence. Lifestar’s vice president testified bonuses were not included when calculating employees’ regular rate of pay. The payroll data then allowed the plaintiff’s expert to identify pay periods where employees received both bonuses and overtime or premium pay. Once that pattern appeared in the data, the dispute became much larger than a single employee’s paycheck.
For California employers, the practical lesson is to review bonus programs for compliance before implementation and before they become litigation exhibits. Employers should identify every form of additional compensation paid to hourly employees, determine whether each payment must be included in the regular rate, document the basis for any exclusion, and confirm payroll systems are applying the correct calculation for overtime, double time, and meal and rest period premium pay.
Martinez v. Sierra Lifestar, Inc. was filed on April 21, 2026, by the California Court of Appeal, Fifth Appellate District, Case No. F089576. The Court of Appeal reversed the trial court’s March 25, 2025 order denying class certification and remanded for further proceedings.
