Jessica JohnsonDoes California overtime start after 8 hours in a day or after 40 hours in a week? The answer is both—and that distinction is the source of some of the most common wage violations in the state.
California Labor Code §510 imposes a daily overtime structure that federal law does not. Non-exempt employees earn 1.5× their regular rate after 8 hours in any workday, regardless of how many hours they worked earlier in the week. Work beyond 12 hours in a single day triggers 2× pay—double-time—and a separate 7th-consecutive-day rule applies on top of the weekly 40-hour threshold. Understanding how these tiers stack, how to calculate the regular rate of pay, and which workers are exempt is essential for both California employees checking their paychecks and employers building compliant payroll systems.
This article is part of the California Labor Law dossier, which covers all six pillars of employment law in the state.
How Does California Overtime Compare to Federal Law?
Federal overtime under the Fair Labor Standards Act (FLSA) is simpler than California's: non-exempt employees earn 1.5× their regular rate after 40 hours in a workweek. There is no daily overtime threshold under federal law. California adds a daily layer that begins at the 9th hour of work—making California's overtime structure both more complex and more protective.
| Category | Federal Law (FLSA) | California Law (Labor Code §510) |
|---|---|---|
| Daily OT threshold | None | 8 hours/day → 1.5× |
| Daily double-time | None | 12 hours/day → 2× |
| Weekly OT threshold | 40 hours/week → 1.5× | 40 hours/week → 1.5× |
| 7th consecutive day | No provision | First 8h → 1.5×; over 8h → 2× |
| Minimum salary for exemption | $684/week (2024) | ~$1,320/week (2× state minimum wage, 2025) |
When California and federal law conflict, the rule most favorable to the employee applies. In practice, this almost always means California law governs, because it is stricter on daily overtime and has a higher salary threshold for exemptions.
California's overtime rules apply to non-exempt employees. That term is defined by both a duties test and a salary basis test—any worker who does not satisfy both tests is non-exempt and entitled to full California overtime protections, even if their employer labels them "manager" or "salaried."
Scenario: Maria works at a distribution center in Riverside. On Monday she works a 13-hour shift; Tuesday she takes the day off. By Tuesday morning she has worked only 13 hours for the week—far below the 40-hour federal threshold. Under federal law, she would earn straight time for all 13 hours. Under California law, she earns straight time for the first 8 hours, 1.5× for hours 9-12, and 2× for hour 13. The daily structure triggers automatically, independent of her weekly total.
What Are the Daily, Weekly, and 7th-Day Overtime Thresholds?
California overtime operates on three independent tracks that can trigger simultaneously in the same pay period. Each track is evaluated separately.
Daily Overtime (Labor Code §510)
- Hours 1-8 in a workday: Straight time (regular rate)
- Hours 9-12 in a workday: 1.5× the regular rate of pay
- Hours 13+ in a workday: 2× the regular rate of pay (double-time)
A "workday" is any consecutive 24-hour period established by the employer—not necessarily a calendar day. Employers set the workday start time, and it must be applied consistently. Changing workday definitions to avoid overtime liability is prohibited under California law.
Weekly Overtime
Any hours worked beyond 40 in a workweek are paid at 1.5×. A workweek is a fixed, regularly recurring 168-hour period (7 consecutive 24-hour periods). Employers choose the workweek start, but once set, it cannot be changed to avoid overtime obligations.
Important: Hours that already triggered daily overtime (hours 9-12 in a given day) are also counted toward the 40-hour weekly total. However, an employee does not receive double overtime pay. California law prevents pyramiding—once hours are compensated at a premium rate on a daily basis, those same hours are not recalculated as weekly overtime. The employee receives the higher of the applicable rates, not both simultaneously.
7th Consecutive Workday Rule
If an employee works all seven days of a single workweek:
- First 8 hours on the 7th consecutive day: 1.5×
- Hours beyond 8 on the 7th consecutive day: 2×
This rule is workweek-specific. A 7th-day premium applies only when the employee has worked every single day in that workweek. Working 6 days in week one and 1 day in week two does not create a 7th-consecutive-day situation.
À retenir: California overtime is not a single threshold—it is three independent layers. Daily, weekly, and 7th-day overtime each trigger autonomously. Payroll systems that only track weekly hours routinely underpay California employees.
How Do You Calculate the Regular Rate of Pay?
Overtime is calculated not on the base hourly rate, but on the regular rate of pay—a broader number that includes most forms of compensation. Miscalculating the regular rate is one of the most common causes of underpaid overtime claims in California.
What Counts Toward the Regular Rate
The regular rate of pay includes all remuneration for employment paid to the employee, with specific exceptions defined by the FLSA and California law:
- Base hourly wages or salary equivalent
- Non-discretionary bonuses (bonuses tied to meeting production targets, attendance, or other predetermined criteria)
- Commissions earned during the pay period
- Shift differentials (premium pay for working nights, weekends, or holidays on a regular basis)
- On-call pay when the employee is required to remain available
- Production bonuses or piece-rate payments
What Is Excluded from the Regular Rate
- Truly discretionary bonuses (where the employer retains full discretion over amount and timing with no prior announcement to employees)
- Gifts for special occasions that are not tied to hours or production
- Reimbursement of legitimate business expenses
- Premium payments for hours worked on holidays (when paid voluntarily by the employer, not contractually required)
- Contributions to qualified retirement plans or health benefits
Step-by-Step: Calculating the Regular Rate for an Employee With a Bonus
- Total base pay: Calculate the straight-time wages for all hours worked in the workweek at the hourly rate. Example: 48 hours × $20/hr = $960.
- Add non-discretionary bonus: If the employee earned a $100 production bonus that week, add it: $960 + $100 = $1,060.
- Divide by total hours: $1,060 ÷ 48 hours = $22.08 regular rate of pay.
- Calculate overtime premium: The first 40 hours are already compensated in step 1. The 8 overtime hours owe an additional 0.5× (half-time premium): 8 hours × ($22.08 × 0.5) = $88.33 in overtime premium.
- Total compensation: $1,060 + $88.33 = $1,148.33.
If the employer simply paid the 8 overtime hours at $20 × 1.5 without incorporating the bonus into the regular rate, the employee would receive less than California law requires. The California Division of Labor Standards Enforcement (DLSE) regularly audits for this calculation error. [California DIR]
Which Employees Are Exempt from California Overtime?
California recognizes several categories of overtime exemptions, but they are interpreted narrowly. An employer cannot create exemptions by job title or salary alone. Both a salary basis test AND a duties test must be satisfied. Failing either test means the employee is non-exempt and entitled to full overtime.
White-Collar Exemptions: Executive, Administrative, and Professional
Salary requirement (2025): To qualify for any white-collar exemption, the employee must earn a salary of at least twice the state minimum wage for full-time employment. Based on California's $16.50/hr minimum wage (2025), this translates to $68,640 per year (or $1,320 per week). The salary threshold adjusts annually with the state minimum wage [California Labor Code §515].
Executive exemption: Primary duty is management of the enterprise or a recognized department; customarily and regularly directs two or more employees; has authority to hire/fire or whose recommendations are given particular weight.
Administrative exemption: Primary duty is office or non-manual work directly related to general business operations; regularly exercises discretion and independent judgment on significant matters. Customer service representatives, data entry workers, and most production-line supervisors do NOT qualify.
Professional exemption: Primary duty is work requiring advanced knowledge in a field of science or learning customarily acquired through a prolonged course of specialized intellectual instruction; or work requiring invention, imagination, or talent in a recognized artistic field.
Other California Overtime Exemptions
| Exemption | Key Conditions |
|---|---|
| Outside salesperson | Primary duty is selling away from employer's place of business |
| Computer software professional | Primarily engaged in software creation; earns ≥$53.80/hr or $112,065.20/year (2025) |
| Licensed physician/surgeon | Engaged in practice; earns ≥$101.22/hr (2025) |
| Certain agricultural workers | Specific wage order and size-of-employer rules apply |
| Alternative workweek (AWS) employees | Only if AWS properly adopted; reduces but does not eliminate OT |
Healthcare and fast-food workers earning the sectoral minimum wage under SB 525 or AB 1228 are still generally subject to standard California overtime rules unless a specific exemption applies to their role and employer type.
Workers covered by valid collective bargaining agreements (CBAs) may have modified overtime rules if the CBA explicitly provides for different overtime and establishes a regular rate of pay, premium wage rates for overtime, and a regular work schedule. The CBA cannot provide a rate lower than California's minimums. For more on CBA structures, see the guide on collective bargaining agreements.
What Is an Alternative Workweek Schedule?
An Alternative Workweek Schedule (AWS) allows non-exempt employees in California to work shifts longer than 8 hours without triggering daily overtime, as long as the schedule is properly adopted. Common AWS examples include four 10-hour days (4/10) or three 12-hour days plus one 4-hour day.
Requirements for a valid AWS:
- The employer proposes a specific schedule for a "work unit" (all employees in a defined group with the same schedule)
- Employees vote by secret ballot; two-thirds must approve the schedule for it to take effect
- The employer files the results with the California Division of Labor Statistics and Research
- The schedule is posted in the workplace and maintained consistently
How overtime is calculated under an AWS: Once properly adopted, a 4/10 AWS means:
- Hours 1-10 on a scheduled day: Straight time
- Hours beyond 10 on a scheduled day: 1.5×
- Hours beyond 12 on any day: 2×
- Hours beyond 40 in a workweek: 1.5×
- All 7th-day rules still apply
Employer mistakes: Many employers try to implement informal AWS-style schedules by simply telling employees to work four 10-hour days. Without the secret ballot election and filing, those schedules are not valid AWS under California law—employees working 10-hour days without a formal AWS are owed daily overtime for hours 9 and 10 of each shift.
"We see AWS election defects frequently in audits," notes a California employment law practitioner specializing in wage and hour compliance. "The employer has the documentation and believes the schedule is valid, but the underlying election process was flawed—no secret ballot, or the wrong work unit was defined. All that daily overtime exposure was sitting there unrecognized for years."
How Do You Recover Unpaid Overtime in California?
Employees who believe they have been underpaid on overtime have two main enforcement paths in California: a wage claim filed with the California Labor Commissioner's Office, or a private civil lawsuit.
Filing a Wage Claim with the DLSE
The Division of Labor Standards Enforcement (DLSE) administers wage claims at no cost to the employee. The process:
- Gather documentation. Collect pay stubs, timesheets, work schedules, and any communications with the employer about hours or pay. If you do not have timesheets, write down the hours you recall working, with as much specificity as possible.
- File a wage claim online or in person. Claims can be filed at any DLSE regional office or through the California Labor Commissioner's website at www.dir.ca.gov/dlse. The form asks for your employer's information, dates of employment, and the nature of the violation.
- Attend the settlement conference. The DLSE schedules a conference where a deputy labor commissioner mediates between the employee and employer. Many cases resolve at this stage.
- Request a hearing. If the case does not settle, the deputy labor commissioner holds a formal hearing and issues an Order, Decision, or Award (ODA). The ODA can order back wages, interest at 10% per year, and a 25% penalty for late payment of overtime wages [California Labor Code §203.1].
- Collect the judgment. If the employer does not comply with the ODA, the employee can convert it to a civil judgment and pursue collection.
Statute of Limitations for California Overtime Claims
- 3 years: Oral employment contracts, violations of wage orders
- 4 years: Written employment contracts (includes most written overtime policies)
The clock starts from each payday when overtime was due but unpaid—not from the date of termination. This means ongoing violations can generate a claim that reaches back years if the employee acts promptly after leaving.
Private Lawsuits and PAGA Claims
Employees can also sue directly in civil court, or bring a representative action under the Private Attorneys General Act (PAGA). PAGA allows an employee to recover civil penalties on behalf of themselves and other "aggrieved employees" for Labor Code violations. PAGA cases are common in overtime misclassification disputes involving large workforces. Comparing California's enforcement mechanisms to employment laws in other US states illustrates just how robust California's worker enforcement tools are.
Can Employers Require Mandatory Overtime in California?
Yes. California employers can require non-exempt employees to work overtime. An employee who refuses to work mandatory overtime can be disciplined or terminated, provided the termination does not violate other laws (anti-discrimination, whistleblower protections, etc.).
However, mandatory overtime does not excuse the obligation to pay. An employer can require overtime and can discipline for refusal; an employer cannot require overtime AND deny the applicable premium pay. Attempts to structure work arrangements to avoid overtime liability—such as claiming employees are "on call" between tasks, or splitting a single shift across two days—are scrutinized heavily by the DLSE and California courts.
Meal and rest break penalties interact with overtime. If an employer fails to provide a required rest or meal break, the employee is owed one hour of pay at the regular rate (premium pay). That premium hour is not paid at 1.5×—it is a standalone penalty paid at the straight regular rate, separate from overtime compensation. However, it does count toward the total hours worked for purposes of calculating weekly overtime thresholds.
Travel Time and On-Call Time: Are They Counted as Hours Worked?
Two gray areas frequently affect California overtime calculations: travel time and on-call time.
Travel time: Ordinary home-to-work commute time is generally not compensable. However, any travel that occurs during the workday—traveling between job sites, attending an offsite meeting, traveling at the employer's direction—counts as hours worked and is included in overtime calculations. Under the federal Portal-to-Portal Act (incorporated by California law), travel from home to the first job site is typically unpaid, but travel from the first site to a second site during the same day is compensable working time [California DIR, 2024].
On-call time: Whether on-call time is compensable depends on how restrictive the on-call arrangement is. California courts apply a "degree of freedom" test. If an employee must remain near the workplace, respond within a very short window, or cannot meaningfully use their time for personal activities, the on-call period is likely compensable. An employee who carries a phone and can respond within 2 hours while going about normal personal activities is less likely to have compensable on-call time than one required to stay within 15 minutes of the workplace and limit alcohol consumption. Properly classifying on-call obligations is particularly important for healthcare workers and IT operations staff, where on-call requirements are common.
Frequently Asked Questions About California Overtime Law
Are tipped employees eligible for California overtime?
Yes. Tipped employees in California who meet the non-exempt definition are entitled to overtime calculated on their full regular rate of pay, which includes tips and is measured against the California minimum wage floor—not the federal tipped minimum. California does not allow a tip credit, meaning employers cannot pay tipped workers below the state minimum wage.
What happens if my employer misclassifies me as exempt?
Misclassification as exempt is treated as a wage violation under California law. If the employee can demonstrate they were mis-classified—either because their salary was too low or their duties did not meet the exemption test—they are entitled to recover all unpaid overtime, plus interest at 10% per year, plus waiting-time penalties if wages were withheld at separation. Class action lawsuits for systemic misclassification are frequent in California.
Does overtime have to be approved in advance to be compensable?
No. In California, overtime that is suffered or permitted by the employer—even if not formally scheduled or approved—must be paid. If a supervisor knows an employee is working extra hours and does not stop them, those hours are compensable regardless of approval policies. Employers who want to control overtime must prevent it from being worked, not refuse to pay for it after the fact.
How is overtime calculated for a piece-rate worker?
Piece-rate workers are entitled to California overtime on top of their piece-rate earnings. The regular rate for a piece-rate employee is calculated by dividing total piece-rate earnings by total hours worked in the workweek. The employee is then owed an additional 0.5× (or 1× for double-time) of that regular rate for each overtime hour.
Can an employee voluntarily waive California overtime?
No. California overtime rights are statutory and cannot be waived by agreement between the employer and employee. Any contract, agreement, or policy purporting to waive overtime rights is void as against public policy [California Labor Code §1194]. This includes agreements to "comp time" in place of overtime pay—private-sector employees in California cannot receive compensatory time off instead of overtime compensation, unlike some public-sector arrangements.
