How Workers’ Compensation Works in California

Workers’ compensation in California is a well-structured system designed to protect both employees and employers. Let’s break down the key aspects of how it works, focusing on employer responsibilities and employee rights.

Employer Responsibilities

Insurance Requirement

In California, every business with at least one employee must have workers’ compensation insurance. This is mandated by the state to ensure that employees are covered in case of work-related injuries or illnesses. Failure to comply can result in severe penalties, including fines up to $100,000 and even imprisonment.

Insurance Purchase

Employers can purchase workers’ compensation insurance from private insurance companies or through the State Compensation Insurance Fund (State Fund). The State Fund acts as a non-profit entity providing coverage, especially for businesses that can’t find insurance in the private market.

Policy Maintenance

Once an insurance policy is in place, employers must maintain it by paying premiums and keeping the coverage active. They also need to provide new hires with a workers’ compensation pamphlet and post a “Notice to Employees” poster in the workplace. This ensures that employees are aware of their rights and the procedures to follow if they get injured.

Employee Rights

Medical Treatment

When an employee gets injured or falls ill due to work, they are entitled to medical treatment. This includes physician visits, prescription medications, and surgeries if necessary. The goal is to help the employee recover and return to work as soon as possible.

Wage Replacement

If an injury prevents an employee from working, they can receive wage replacement benefits. These benefits come in two forms:

  • Temporary Disability Payments: For employees who can’t perform their usual job while recovering.
  • Permanent Disability Benefits: For employees who suffer long-term or permanent injuries.

No-Fault System

California’s workers’ compensation operates on a no-fault basis. This means that employees do not need to prove that the injury was someone else’s fault to receive benefits. This system simplifies the process and ensures that employees get the support they need without lengthy legal battles.

Benefit Payout

The amount of benefits an employee receives is based on their average weekly wage and the type of benefit. For instance, temporary disability payments typically cover two-thirds of the employee’s average weekly earnings, while permanent disability benefits vary based on the severity of the injury.

Understanding these responsibilities and rights is crucial for both employers and employees to navigate the workers’ compensation system effectively. Next, we’ll delve into the different types of workers’ compensation benefits available in California.

Types of Workers’ Compensation Benefits

Types of Workers’ Compensation Benefits

When it comes to worker comp in California, the benefits are designed to support employees who get injured or sick because of their job. Let’s break down the main types of benefits:

Medical Benefits

Medical benefits cover all necessary treatments to help an injured worker recover. This includes:

  • Physician visits: Regular check-ups and consultations with doctors.
  • Prescription medications: Drugs prescribed by doctors to aid recovery.
  • Surgeries: Operations needed to treat the injury.

For example, in the Leopoldo Hernandez case, the employee required extensive medical treatment, including surgery, for multiple injuries.

Wage Replacement Benefits

If an injury prevents an employee from working, wage replacement benefits kick in. There are two main types:

  • Temporary Disability Benefits: These cover two-thirds of the employee’s average weekly earnings while they recover. For instance, if someone earns $900 per week, they would receive around $600 in temporary disability payments.
  • Permanent Disability Benefits: If the injury leads to lasting impairments, permanent disability benefits provide long-term financial support. The amount depends on the severity of the injury and the employee’s ability to work.

Permanent Disability Benefits

When an injury is so severe that full recovery is impossible, permanent disability benefits come into play. These are crucial for workers who suffer non-recoverable injuries and need long-term support. There are two ways these benefits can be settled:

  • Stipulated Findings and Award: This settlement covers ongoing medical care for permanent disabilities.
  • Compromise and Release: A one-time lump sum payment that resolves the claim.

For instance, in the Erica Cox case, the employee received retroactive temporary disability benefits and a penalty due to the employer’s failure to properly manage the benefits.

These benefits ensure that injured workers receive the care and financial support they need to recover or manage their disabilities. Next, we’ll explore the specifics of workers’ compensation insurance in California.

Workers’ Compensation Insurance in California

Policy Requirements

In California, workers’ compensation insurance is mandatory for all employers, even if you have just one part-time employee. This coverage ensures that employees receive medical treatment and financial support if they get injured or fall ill due to their job.

You can purchase workers’ comp insurance from private insurance companies or through the State Compensation Insurance Fund (State Fund). The State Fund operates as a non-profit entity and serves as the insurer of last resort. This means if private insurers won’t cover your business, the State Fund will step in.

Failing to have workers’ compensation insurance can lead to severe penalties, including:

  • A $10,000 fine
  • Up to one year in prison
  • State penalty up to $100,000


Large businesses sometimes opt for self-insurance. This means they set aside funds to cover potential workers’ comp claims instead of buying insurance from an external provider. Self-insured employers must get approval from the Office of Self-Insurance Plans (SIP). SIP evaluates the financial stability of the business to ensure it can meet its obligations.

Self-insurance is often more cost-effective for large employers with a stable workforce and low injury rates. But it requires rigorous financial planning and administrative oversight.

Cost Factors

The cost of workers’ comp insurance varies based on several factors. Key among these are:

  • Industry Classification: Jobs are classified based on risk levels. For example, clerical jobs are low-risk, while construction jobs are high-risk.
  • Payroll Percentage: Insurance premiums are calculated as a percentage of your payroll. For instance, low-risk jobs may cost around 40 cents per $100 in payroll, while high-risk jobs can go up to $33.57 per $100 in payroll.
  • Claims History: Businesses with a history of frequent claims may face higher premiums.

It’s essential to shop around and compare quotes from different insurers to find the best deal. While cost is important, also consider the insurer’s experience with your industry and their claims handling process.

Next, we’ll walk you through the process of filing a workers’ compensation claim, including timelines and dispute resolution.

Filing a Workers’ Compensation Claim

Claim Process

When an employee is injured at work, they need to report the injury to their employer as soon as possible. In California, employees have one year from the date of injury or illness to file a claim.

Here’s how the claim process works:

  1. Injury Reporting: The employee must report the injury to their employer.
  2. Claim Form Submission: Within one business day of the report, the employer must provide the employee with a workers’ compensation claim form (DWC-1).
  3. Employer’s Responsibilities: After receiving the completed form from the employee, the employer has one business day to:
  4. Provide a completed copy of the claim form to the employee.
  5. Forward the claim form and the employee’s injury report to their insurer or claims administrator.
  6. Authorize up to $10,000 in medical treatment.
  7. Consider authorizing light-duty work if applicable.


Timelines are crucial in the workers’ compensation process. Here are the key deadlines:

  • 14-Day Response: The insurer must respond to the claim within 14 days of receiving it. They may accept, deny, or delay the claim for further investigation.
  • 90-Day Rule: If the insurer delays the claim, they have up to 90 days to make a decision. If no decision is made within this period, the claim is presumed accepted by default.
  • Benefit Duration: Temporary disability benefits can last between three to seven years, depending on the injury. Permanent disability benefits can sometimes continue indefinitely, up to retirement age.

Dispute Resolution

Disputes can arise during the claims process. The Division of Workers’ Compensation (DWC) and the Workers’ Compensation Appeals Board (WCAB) provide services to resolve these issues.

Here’s how dispute resolution works:

  1. DWC Services: The DWC offers administrative and judicial services to help resolve disputes. They can provide information and assistance to both employees and employers.
  2. WCAB Role: The WCAB handles appeals and disputes related to workers’ compensation claims. They review cases and make decisions on contested issues.
  3. Administrative Law Judges: If a dispute cannot be resolved through the DWC, it may go before an administrative law judge. These judges have the authority to make binding decisions on workers’ compensation cases.

For instance, in the case of Allen Scott Chance vs. Time Printing Inc., the petition for reconsideration was dismissed because it was filed late. This underscores the importance of adhering to timelines in the dispute resolution process.

Next, we’ll look at recent changes in California workers’ comp laws and how they impact both employers and employees.

Recent Changes in California Workers’ Comp Laws

California’s workers’ comp laws have seen significant updates. These changes aim to improve coverage and streamline processes. Here’s what you need to know about the new legislation and how it impacts employers and employees.

New Legislation

In July 2023, California introduced several changes to its workers’ comp laws. One of the most notable updates is the mandatory insurance for contractors. This rule requires contractors in specific trades to carry workers’ comp insurance, regardless of whether they have employees.

Effective Dates: These changes took effect on July 1, 2023. Contractors must comply immediately to avoid penalties.

Specific Trades: The law primarily targets high-risk industries like construction, roofing, and electrical work. These trades often see higher injury rates, making insurance crucial.

Impact on Employers and Employees

Compliance: Employers must ensure they have the required insurance. Failure to comply can result in fines, business closures, or even imprisonment. The Division of Labor Standards Enforcement can issue stop orders to non-compliant businesses.

Benefits: For employees, these changes mean better protection. Workers in previously uncovered trades now have access to medical treatment, wage replacement, and other benefits if injured on the job.

Legal Implications: Employers must understand the legal implications of these changes. Non-compliance can lead to severe penalties, including fines up to $100,000 and imprisonment for up to a year. Additionally, uninsured employers are liable for all injury-related costs and may face civil lawsuits.

These updates highlight the importance of staying informed and compliant with California’s workers’ comp laws. Up next, we’ll answer some frequently asked questions about workers’ comp in California.
