California Workers’ Compensation Alternative Dispute Resolution: How ADR Programs Work
California workers’ compensation Alternative Dispute Resolution, commonly called ADR, is a collectively designed way to address questions and resolve covered disputes through Program procedures rather than automatically beginning every disagreement in the ordinary state-system dispute process. Depending on the governing ADR Agreement and Program Rules, the process may include Ombudsman assistance, mediation, arbitration and specialized procedures.
ADR is not one event and it is not simply another name for settlement.
It is a progression in which the amount of formality and decision-making authority can increase as the dispute becomes clearer and remains unresolved.
Information only: This page provides general educational information about California workers’ compensation Alternative Dispute Resolution Programs. It does not provide medical advice, legal advice or financial advice; interpret a particular collective bargaining agreement, labor-management agreement, ADR Agreement or Program Rule; determine whether a claim or benefit is payable; calculate compensation; recommend a litigation or settlement strategy; or evaluate the merits of an individual dispute.
The applicable law, claim facts, insurance coverage, collective bargaining or labor-management agreement, ADR Agreement and current Program Rules control.
What does ADR mean in California workers’ compensation?
Alternative Dispute Resolution is a broad term for organized methods of addressing disagreements without requiring every question or dispute to begin in the ordinary adjudicatory process. ADR may involve direct negotiation, informal inquiry, facilitated communication, mediation, arbitration or another procedure authorized by the governing law and Program documents.
In California workers’ compensation, the term has a more specific setting. Labor Code sections 3201.5 and 3201.7 authorize qualifying labor-management arrangements to establish an alternative dispute-resolution system governing disputes between employees and employers or their insurers. That system may supplement or replace all or part of the ordinary dispute-resolution processes contained in Division 4 of the Labor Code.
The California Division of Workers’ Compensation commonly refers to these arrangements as labor-management or workers’ compensation carve-out programs. The phrase does not mean that a covered claim is removed from California workers’ compensation law. It means that an authorized agreement may establish different procedures for benefit delivery and dispute resolution.
The Program may be carved out from specified ordinary procedures; the covered claim is not carved out from California workers’ compensation law.
ADR Programs are not identical. The agreement and current Program Rules determine which participants and claims are covered, which procedures apply, how a matter begins, what prerequisites must be completed, which deadlines govern and who has authority to decide an unresolved issue.
Why do people and organizations want ADR?
People usually do not want ADR merely because it is described as an alternative. They want a process that fits the actual problem. A question should not necessarily require the same procedure as a contested claim issue, and a matter that can be clarified or negotiated should not automatically require a formal hearing.
The practical value of ADR is therefore proportionality: applying the amount of structure, neutral assistance and decision-making authority that the matter presently requires.
| Participant need | Possible ADR response | Practical value |
|---|---|---|
| A place to begin | An accessible Program contact or Office of the Ombudsman. | A participant can ask a question, identify the applicable Program and determine the appropriate procedure without immediately requesting adjudication. |
| Clearer communication | Focused inquiry, information exchange or impartial facilitation. | Missing information, unanswered communication and correctable administrative problems may be addressed before positions become unnecessarily entrenched. |
| Control over an agreed outcome | Negotiation or mediation. | The participants can consider complete, partial, conditional or procedural agreements rather than surrendering every issue to a decision-maker. |
| A final decision when agreement is not possible | Binding arbitration under the governing Program. | An unresolved controversy has a defined adjudicatory route instead of remaining indefinitely stalled. |
| Procedures suited to the covered workforce | Collectively bargained forms, contacts, stages, provider arrangements and administrative procedures. | Labor and management can design a process informed by the industry, workforce, claim environment and recurring operational needs. |
| Continuity and institutional knowledge | Program participants and neutrals familiar with the governing agreement and procedures. | Recurring procedural questions may be addressed within a system that understands the Program rather than being reconstructed from the beginning in every matter. |
ADR may reduce unnecessary formality, delay, expense, misunderstanding and conflict when it is properly designed, communicated and administered. Those results are not guaranteed. A poorly defined procedure, inaccessible neutral, unclear deadline or failure to exchange necessary information can make an ADR process as difficult as any other dispute system.
ADR should therefore be evaluated by the quality of its design and operation, not by the label placed on it.
Three common workers’ compensation ADR stages
Ombudsman assistance, mediation and arbitration are related, but they are not interchangeable names for the same function. Each stage addresses a different need and places decision-making authority in a different location.
Office of the Ombudsman: clarify and connect
The workers’ compensation ADR Ombudsman is often the early information, inquiry and informal problem-solving resource. Depending on the Program, the Ombudsman may help identify coverage, explain procedures, locate missing information, make inquiries, facilitate communication and help define an unresolved issue.
The Ombudsman does not issue a binding award, order or decision. An informal outcome occurs because the responsible participants clarify, correct or agree to something—not because the Ombudsman adjudicates the claim.
Mediation: negotiate with assistance
Workers’ compensation mediation provides a structured opportunity to negotiate a defined dispute. The mediator may help identify agreed and disputed facts, organize the discussion, explore interests, test proposals and document an agreement reached by the participants.
The mediator manages the process but does not decide who wins and cannot force a participant to settle. A mediation may produce a complete settlement, partial agreement, procedural agreement, continued negotiation or no agreement.
Arbitration: obtain a decision
Workers’ compensation ADR arbitration is adjudicative. The arbitrator receives evidence and argument and determines the unresolved issues properly submitted under the governing agreement, Program Rules and applicable law.
Labor Code sections 3201.5 and 3201.7 provide that the arbitrator’s findings of fact, award, order or decision have the same force and effect as those of a workers’ compensation administrative law judge. The arbitration system must also provide for review by the Workers’ Compensation Appeals Board and subsequent judicial review through the statutory procedures identified in those sections.
Arbitration is binding because the arbitrator decides the submitted controversy. Binding does not mean immune from the review process provided by California workers’ compensation law.
California’s collectively bargained workers’ compensation ADR framework
California’s workers’ compensation ADR framework is based on labor-management agreement rather than a unilateral employer decision. The applicable union must be the recognized or certified exclusive bargaining representative, and the participating employers, employer groups or other authorized entities must satisfy the applicable statutory and regulatory requirements.
The California Division of Workers’ Compensation describes carve-out programs as arrangements that allow employers and unions to create their own alternatives for workers’ compensation benefit delivery and dispute resolution under a collective bargaining or labor-management agreement. Eligibility to participate must be approved by the Administrative Director.
Labor Code section 3201.5
Section 3201.5 applies to qualifying private employers or groups of employers engaged in construction, construction maintenance and the additional construction-related activities identified in the statute. It authorizes qualifying collective bargaining provisions establishing an alternative dispute-resolution system and certain related medical, safety and return-to-work arrangements.
Labor Code section 3201.7
Section 3201.7 authorizes qualifying labor-management arrangements in industries outside the section 3201.5 framework. It contains its own bargaining, eligibility and administrative-approval requirements.
Review the official text of California Labor Code section 3201.5 and California Labor Code section 3201.7.

What ADR may change and what it may not diminish
The distinction among processes, delivery and payments is central to understanding California workers’ compensation ADR.
Sections 3201.5 and 3201.7 authorize qualifying agreements to establish alternative dispute-resolution processes and specified systems involving medical providers, medical evaluators, safety, return to work and benefit delivery. Separately, both statutes prohibit an agreement from diminishing the employee’s entitlement to the protected compensation payments and employer-paid medical treatment identified in the applicable section.
| A qualifying agreement may establish a different process for | The existence of ADR does not mean |
|---|---|
| Ombudsman assistance, mediation, arbitration and Program-specific dispute stages. | That protected compensation payments may be reduced merely because a different dispute process applies. |
| Program forms, notices, communication routes, filing procedures and prerequisites. | That a participant may disregard statutory or Program deadlines. |
| An agreed list or system of medical-treatment providers. | That employer-paid medical-treatment protection may be diminished contrary to the governing statute. |
| An agreed, limited list of qualified medical evaluators and agreed medical evaluators. | That a different evaluator process automatically changes the underlying compensation entitlement. |
| Joint labor-management safety committees and authorized return-to-work arrangements. | That the ADR process guarantees a particular medical, benefit, employment or claim outcome. |
| Negotiated procedures concerning delivery of medical benefits and disability compensation when authorized. | That the Ombudsman or mediator acquires adjudicatory authority not granted by the agreement and Program Rules. |
ADR may address a disagreement concerning whether a payment is due, what period is involved, what wage or medical information applies, how the amount is calculated or which procedure governs. The authorization to use a different process is not authorization to diminish the protected payment entitlement.

A brief history of California workers’ compensation ADR
California’s statutory workers’ compensation carve-out framework began with the workers’ compensation reforms enacted in 1993. Senate Bill 983 authorized qualifying construction employers and unions to establish alternative arrangements for benefit delivery and dispute resolution, resulting in Labor Code section 3201.5.
The California Commission on Health and Safety and Workers’ Compensation has reported that the California construction approach was influenced in part by an earlier labor-management experiment involving a Massachusetts construction project. The California model placed that experimental idea into a statutory framework requiring collective bargaining, protected benefit levels and a route for review of arbitration decisions.
In 2003, Senate Bill 228 expanded the framework through Labor Code section 3201.7, allowing qualifying labor-management arrangements in nonconstruction industries. The legislation and later guidance reinforced the concept that workers’ compensation ADR is more than a single mediation or arbitration clause: it can be an integrated labor-management system for benefit delivery, inquiry, dispute resolution, safety and return to work.
Historical information is available from the Commission on Health and Safety and Workers’ Compensation and in the DWC report on ADR/carve-out Program activities.
What makes an ADR system a viable solution?
ADR is viable when participants can understand the process, trust the assigned functions and obtain either an informed agreement or a legitimate decision. Merely naming a procedure “ADR” does not create those conditions.
Clear scope and authority
Participants should be able to determine which employees, employers, claims, dates and issues are governed by the Program. The agreement and Rules should identify which processes replace ordinary procedures and which matters remain governed by another statutory route.
An accessible point of entry
Participants need a practical way to ask questions, identify the correct claim or Program contact and determine the appropriate next step. An inaccessible process encourages confusion, delay and premature escalation.
Impartial and appropriately qualified neutrals
The role, authority, selection method and conflict standards of the Ombudsman, mediator and arbitrator should be clearly established. Each neutral should remain within the function assigned to that stage.
Proportionate escalation
Informational questions and correctable administrative problems should not require unnecessary adjudication. At the same time, a matter that cannot be resolved informally must have a reliable path to a binding determination.
Written procedures and understandable deadlines
The Program should identify forms, triggering events, service requirements, prerequisites, response periods and the consequences of failing to act. Participants should not have to guess whether an informal communication also constitutes a formal filing.
Protection of substantive rights
A change in procedure should not be confused with permission to diminish the protected compensation payments or employer-paid medical treatment preserved by the governing statute.
Labor-management oversight and continuing improvement
Because the Program is collectively bargained, labor and management can review recurring communication problems, administrative patterns, participant education, neutral performance and possible procedural improvements without deciding individual claims through the oversight process.
ADR is viable not because it eliminates rules, but because it can replace procedural uncertainty with agreed rules and match the authority of the process to the needs of the dispute.
How to get oriented in an ADR-covered workers’ compensation matter
A participant does not need to understand every aspect of the claim before asking for information. It is nevertheless helpful to identify the governing Program and state the issue as precisely as possible.
- Confirm possible Program coverage. Identify the employee, employer, union, work location, date of injury or claimed injury period and applicable ADR Program.
- Identify the exact event or concern. Note the notice, request, response, payment period, medical report, communication or missing action involved.
- Review the current Program materials. Use the applicable ADR Agreement, Program Rules, forms and participant instructions rather than assuming that an ordinary WCAB form or state-system route applies.
- Separate an information problem from a contested decision. Determine whether the concern involves missing information, an administrative delay, a communication failure, a defined disagreement or an issue requiring adjudication.
- Contact the participant or Program resource with the appropriate function. The claims administrator ordinarily remains responsible for day-to-day claim administration. The Ombudsman may assist with Program information, inquiry, communication and identification of the next authorized procedure.
- Preserve notices and deadlines. Contacting the Ombudsman or discussing an issue informally does not automatically toll, pause, extend or restart a deadline unless the governing law, agreement or Program Rules expressly provide that effect.
Participants who know the applicable Program may use My ADR Program to access Program information. A participant with a question involving an existing ADR-covered claim or case may contact the Office of the Ombudsman.
Frequently asked questions about workers’ compensation ADR
Is ADR the same as settlement?
No. Negotiation and mediation may result in a voluntary agreement, but ADR also includes procedures that do not depend on settlement. Arbitration is an adjudicatory process in which the arbitrator issues a binding award, order or decision concerning the issues properly submitted.
Does every workers’ compensation ADR Program use the same process?
No. Programs may share common features, but the ADR Agreement and current Program Rules determine coverage, stages, prerequisites, forms, deadlines, neutral selection and specialized procedures. Participants should not assume that a procedure used by one Program applies to another.
Is an Ombudsman inquiry the same as mediation?
No. Ombudsman assistance commonly focuses on information, inquiry, communication and early problem identification. Mediation is a more structured negotiation concerning a defined dispute. Neither the Ombudsman nor the mediator ordinarily issues a binding decision while performing that role.
Can a mediator force the participants to settle?
No. The mediator can organize discussions, identify issues and explore proposals, but the participants decide whether to enter into an agreement. Participation in a mediation stage may be required by the Program even though acceptance of a settlement proposal remains voluntary.
Is a workers’ compensation ADR arbitration decision binding?
Yes, when issued within the arbitrator’s authority concerning properly submitted issues. Labor Code sections 3201.5 and 3201.7 provide that the arbitrator’s findings, award, order or decision have the same force and effect as those of a workers’ compensation administrative law judge. The decision remains subject to the statutory reconsideration and judicial-review procedures.
Can a workers’ compensation ADR Program reduce protected benefit payments?
Sections 3201.5 and 3201.7 prohibit an authorized agreement from diminishing the protected compensation-payment and employer-paid medical-treatment entitlements identified in the applicable statute. ADR may change authorized processes and delivery systems; that authority is not permission to diminish the protected entitlement.
Does contacting the Ombudsman extend a filing deadline?
Not automatically. Contacting the Ombudsman, discussing an issue informally or later involving an attorney does not by itself toll, pause, extend or restart a statutory or Program deadline. The governing law, ADR Agreement and Program Rules must be reviewed to determine whether a particular provision changes a particular deadline.
Are all ADR communications confidential?
Participants should not assume blanket confidentiality. Treatment of communications and documents may depend on the governing law, ADR Agreement, Program Rules, mediation agreement, professional standards and ground rules established for the particular proceeding.
May a participant privately consult an attorney?
Yes. Private legal consultation is distinct from an attorney’s direct appearance in a Program proceeding. Section 3201.7 expressly protects representation by counsel at all ADR stages. In a section 3201.5 Program, the governing agreement and Program Rules may contain stage-specific provisions concerning an attorney’s direct participation. A notice of representation may also be required before the Program recognizes an attorney of record.
Does every disagreement have to proceed to arbitration?
No. Many questions are resolved through direct claim administration, information exchange or Ombudsman assistance. Other disputes may settle in mediation or use a specialized procedure. Arbitration is used when an issue requiring adjudication remains unresolved and the governing prerequisites for arbitration have been satisfied.
