An Introduction to Workers’ Compensation Practice Areas in California

Designed to protect employees who suffer work-related injuries or illnesses, California’s workers’ compensation system provides a framework for medical treatment, wage replacement, and other benefits. For attorneys practicing in this area, understanding the various practice areas within workers’ compensation law is essential to effectively representing injured workers, employers, and insurers. 

Overview of the California Workers’ Compensation System

California’s workers’ compensation laws are governed by the California Labor Code and administered by the Division of Workers’ Compensation (DWC). The system operates on a no-fault basis, meaning that injured employees are entitled to benefits regardless of who was at fault for the injury.

Purpose of the System

The core objectives of California’s workers’ compensation system are to:

• Provide prompt and adequate medical treatment to injured workers.
• Replace lost wages during periods of temporary or permanent disability.
• Facilitate the injured worker’s return to work.
• Protect employers from civil lawsuits arising from workplace injuries.

Key Stakeholders

The main parties involved in workers’ compensation cases include:

• Injured Workers – Employees seeking medical and financial benefits.
• Employers – Responsible for providing workers’ compensation insurance.
• Insurance Companies – Manage claims and payments.
• Medical Providers – Treat injured workers and report medical progress.
• Defense and Applicant Attorneys – Represent insurers and injured workers, respectively.

Practice Area #1: Claims for Work-Related Injuries and Illnesses

The most common practice area involves representing employees who have suffered work-related injuries or illnesses. 

Establish a Compensable Injury

To succeed in a workers’ compensation claim, the injury must be shown to have arisen out of and in the course of employment (AOE/COE). Common types of compensable injuries include:

• Traumatic Injuries – Resulting from a specific event (e.g., fall, machinery accident).
• Repetitive Stress Injuries – Developed over time due to repetitive tasks (e.g., carpal tunnel syndrome).
• Occupational Illnesses – Caused by exposure to harmful substances or work conditions (e.g., asbestosis, hearing loss).

Medical Treatment and Reporting

California law requires that injured workers receive medical treatment through an approved Medical Provider Network (MPN). Attorneys often litigate disputes over:

• Denied or delayed medical treatment.
• Adequacy of medical care.
• Independent Medical Review (IMR) decisions under Labor Code § 4610.5.

Disability Benefits

Injured workers may be entitled to:

• Temporary Disability (TD) Benefits – Wage replacement during recovery.
• Permanent Disability (PD) Benefits – Compensation for permanent loss of function.
• Supplemental Job Displacement Benefits – Vouchers for retraining if the worker cannot return to their former job.

Practice Area #2: Cumulative Trauma Claims

Cumulative trauma claims arise from injuries or illnesses that develop gradually over time due to repeated exposure to harmful work conditions. These cases are inherently more difficult to prove due to the lack of a single identifiable event.

Challenges in Cumulative Trauma Cases

• Establishing causation between work conditions and the injury.
• Differentiating between work-related injuries and pre-existing conditions.
• Overcoming employer and insurer defenses based on lack of timely notice or statute of limitations.

Legal Strategy

• Obtain comprehensive medical evaluations to establish causation.
• Use expert testimony to demonstrate the link between work activities and the injury.
• Argue that the cumulative nature of the injury tolls the statute of limitations.

Practice Area #3: Psychiatric and Stress-Related Claims

Psychiatric injuries and stress-related claims are highly contested due to the subjective nature of the symptoms and the higher standard of proof required under California law.

Eligibility Requirements

Under Labor Code § 3208.3, a psychiatric injury is compensable if:

• The worker was employed for at least six months.
• The injury resulted from actual events of employment (not personnel actions).
• The injury caused at least 51% of the worker’s psychological impairment.

Common Defenses

• Stress resulted from lawful, non-discriminatory personnel actions (e.g., demotions, performance reviews).
• Pre-existing mental health conditions are responsible for the symptoms.
• Fraud or malingering.

Litigation Strategy

• Present credible medical and psychiatric testimony.
• Argue that workplace stress was unreasonable or extreme.
• Demonstrate the cumulative impact of work conditions on mental health.

Practice Area #4: Employer Defenses and Fraud Claims

Employers and insurers frequently raise legal defenses to limit or deny workers’ compensation liability. Common defenses include:

• Intoxication Defense – The injury was caused by the worker’s drug or alcohol use.
• Willful Misconduct – The injury resulted from the worker’s intentional violation of workplace safety rules.
• Going and Coming Rule – The injury occurred during a commute and is not work-related.

Fraudulent Claims

Workers’ compensation fraud remains a significant issue in California. Fraudulent claims can include:

• Faking or exaggerating injuries.
• Claiming benefits for non-work-related injuries.
• Misrepresenting job duties or work capacity.

Strategic Considerations

• Depose the claimant and witnesses to identify inconsistencies.
• Use surveillance and social media to identify misrepresentation.
• File a petition for dismissal based on fraud findings.

Practice Area #5: Third-Party Liability and Subrogation

When a third party (other than the employer) causes a work-related injury, the injured worker may file a civil lawsuit against that party while also receiving workers’ compensation benefits.

Examples of Third-Party Claims

• Car accidents during work-related travel.
• Injuries caused by defective machinery or equipment.
• Injuries caused by contractors or other non-employer personnel.

Subrogation Rights

Under Labor Code § 3852, employers and insurers may recover compensation costs from third-party settlements.

• Defense counsel should coordinate with civil litigators to protect the employer’s recovery rights.
• Applicant’s counsel should negotiate lien reductions to maximize the client’s net recovery.
