PIPE Trust Workers’ Compensation ADR Program

A collectively bargained workers’ compensation system for covered Southern California plumbing and pipefitting employees

The PIPE Trust Workers’ Compensation Alternative Dispute Resolution Program provides a specialized system for administering and resolving workers’ compensation matters involving covered employees of participating signatory employers.

The ADR Program was established through collective bargaining under California Labor Code Section 3201.5. It remains part of the California workers’ compensation system, but it uses a labor-management-designed process instead of beginning with the ordinary dispute-resolution procedures of the Workers’ Compensation Appeals Board.

For injured employees, the ADR Program provides a dedicated Office of the Ombudsman, a defined process for addressing claim problems, access to approved medical providers, and a pathway for resolving disagreements through ombudsman assistance, mediation, and, when necessary, arbitration. The goal is to help the people involved communicate, address problems, and move the claim forward without unnecessary litigation.

What the ADR Program changes—and what it does not

The Program changes how covered workers’ compensation claims, medical care, benefit delivery, and disputes are administered. It does not remove covered employees from California workers’ compensation protection or authorize any reduction in their entitlement to disability compensation payments or other benefits protected by California law.


Who is covered by the Program?

The Program generally applies when:

  • The employee is covered by the applicable collective bargaining agreement.
  • The employee was working for a participating signatory employer.
  • The claimed injury arose out of and occurred in the course of covered employment.
  • The claim otherwise comes within the scope of the PIPE Trust ADR Agreement and Program Rules.

The ADR Program is associated with the Piping Industry Progress and Education (P.I.P.E.) Trust Fund and the Southern California Pipe Trades District Council 16, and participating plumbing and piping industry employers. The Program is overseen by the P.I.P.E. Trust Fund Joint Labor Management Safety Committee, through which labor and management jointly administer the Program and approve its medical and dispute-resolution service providers.

The California Division of Workers’ Compensation identifies the arrangement as a multi-employer construction carve-out involving Southern California Pipe Trades District Council 16 and the Plumbing & Piping Industry Council.

Coverage is determined by the governing collective bargaining agreement, the ADR Agreement, the employee’s employment circumstances, and applicable law. Merely being a union member, working for a plumbing or piping contractor, or participating in another P.I.P.E. Trust activity does not necessarily mean that every injury or employment relationship is covered by the Program.*


Why does this ADR Program exist?

Workers’ compensation claims can involve many participants: the injured employee, employer, union, insurance carrier, claims administrator, physicians, medical facilities, vocational professionals, and attorneys. Even a relatively straightforward claim can become delayed when information is incomplete, responsibilities are unclear, or the participants disagree about medical care, benefits, compensability, disability, or return to work.

California Labor Code Section 3201.5 allows qualifying construction unions and employers to design a collectively bargained system that is better connected to their industry and workforce.

The PIPE Trust ADR Agreement was created with the stated objectives of improving access to high-quality medical care, reducing the number and severity of disputes, and providing a more efficient and effective method for addressing disagreements arising from work-related injuries. Its intended dispute-resolution structure uses an ombudsman, mediation, and arbitration rather than immediately placing every disagreement into formal litigation.

The underlying concept is straightforward:

Problems should be identified early, the right people should be brought into the discussion, and reasonable efforts should be made to solve the problem before formal adjudication becomes necessary.

This does not mean every disagreement will be resolved informally. It means that the Program provides an organized opportunity to resolve issues before requiring the parties to proceed to a formal hearing.


How the ADR Program works

The PIPE Trust ADR Program uses a progressive dispute-resolution structure. The ADR Program Rules describe the ombudsman and mediation stages as pre-litigation processes and arbitration as the Program’s formal litigation stage.

1. Office of the Ombudsman

The Office of the Ombudsman is the primary point of contact for questions, concerns, and unresolved claim issues.

An injured employee may contact the Office of the Ombudsman when:

  • The employee does not understand what is happening with the claim.
  • Calls or correspondence have not produced a clear answer.
  • Medical care appears to be delayed or interrupted.
  • There is confusion concerning benefits, medical reports, work status, or claim administration.
  • The employee believes that a claim-related issue requires attention.
  • The employee needs information about the ADR process or available ADR Program forms.

The Ombudsman gathers information, communicates with the appropriate participants, explains the Program process, and attempts to help the parties reach a practical resolution. The Ombudsman may also assist an employee with the procedures needed to advance an unresolved dispute to the next Program stage.

The Ombudsman does not decide contested issues and does not replace the claims administrator, treating physician, mediator, arbitrator, or legal counsel. The Ombudsman’s role is to help identify the problem, improve communication, and facilitate a workable response.

2. Mediation

When a dispute cannot be resolved with ombudsman assistance, the matter may proceed to mediation under the ADR Program.

Mediation gives the employee and the employer or claims administrator an opportunity to discuss the disagreement with an experienced mediator. The mediator does not impose a result. Instead, the mediator works with the parties to clarify the issues, exchange relevant information, explore possible solutions, and determine whether an agreed resolution can be reached.

Mediation can be especially useful when a dispute results from misunderstanding, incomplete documentation, differing interpretations of medical information, or a breakdown in communication.

3. Arbitration

When the parties cannot resolve a dispute through the Program’s preliminary stages, the issue may proceed to arbitration.

Arbitration is the Program’s formal adjudicatory process. An approved arbitrator receives evidence, determines the disputed issues, and issues an order, decision, or award. The ADR Program Rules require the arbitrator to apply California statutory and decisional law except where a modification is expressly authorized under Labor Code Section 3201.5.

An arbitrator’s decision has the same force and effect as a decision of a California workers’ compensation administrative law judge. It remains subject to reconsideration by the Workers’ Compensation Appeals Board and judicial review through the California appellate courts as provided by law.

4. Attorney Participation and the Right to Consult Counsel

The PIPE Trust ADR Program distinguishes between an attorney’s participation in the ADR process and a party’s right to consult an attorney privately.

During the Ombudsman and mediation stages, attorneys do not participate in communications or proceedings on behalf of an employee, employer, or claims administrator. The parties communicate directly with the Ombudsman or mediator so that questions and disputes may be addressed through direct, informal problem-solving.

This limitation does not prevent an employee or employer from consulting an attorney, obtaining legal advice, or discussing the claim privately with counsel at that party’s own expense. An attorney who provides private advice does not thereby become a participant in the Ombudsman or mediation stage.

If a dispute proceeds to arbitration, either party may have an attorney participate. Arbitration is the Program’s formal adjudicatory stage, during which evidence may be presented and the arbitrator may issue a binding order, decision, or award.

The Ombudsman may explain Program procedures and assist with claim-related communication, but does not provide legal advice.


What California Labor Code Section 3201.5 allows

Section 3201.5 does not create an entirely separate type of workers’ compensation benefit. It permits qualifying labor and management organizations to collectively bargain over certain aspects of how workers’ compensation medical care, claim disputes, and related services are delivered.

A qualifying agreement may establish:

A different dispute-resolution system

The agreement may supplement or replace some or all of the ordinary Division of Workers’ Compensation dispute-resolution process with procedures such as ombudsman review, mediation, and arbitration.

For claims within the PIPE Trust ADR Program’s jurisdiction, disputes are therefore handled through the Program rather than being filed initially for adjudication before a Workers’ Compensation Appeals Board judge.

An agreed medical provider system

Labor and management may establish an agreed list of medical treatment providers. Section 3201.5 permits that list to be the exclusive source of treatment for covered claims, subject to the terms of the agreement and applicable law.

This allows labor and management to participate jointly in identifying physicians and facilities considered suitable for the covered workforce.

Agreed medical evaluators

The parties may establish a limited list of qualified medical evaluators and agreed medical evaluators for resolving disputed medical questions.

Joint labor-management safety oversight

The law permits the creation of joint labor-management safety committees. In the PIPE Trust ADR Program, the Joint Labor Management Safety Committee provides oversight of the Program and approves service-provider lists, including medical and dispute-resolution professionals.

Return-to-work programs

The parties may collectively bargain light-duty, modified-duty, and return-to-work programs intended to help employees resume safe and suitable employment when medically appropriate.

Rehabilitation and retraining arrangements

The agreement may establish vocational rehabilitation or retraining programs and may use agreed providers for those services.

These subjects are expressly identified in Section 3201.5 as matters that qualifying unions and employers may address through collective bargaining.


What California Labor Code Section 3201.5 does not allow

The term “carve-out” can be misunderstood. It does not mean that injured employees are carved out of workers’ compensation protection or that their benefits may simply be taken away.

California Labor Code Section 3201.5 places important limits on what labor and management may change.

It does not permit bargaining away workers’ compensation benefits

A Section 3201.5 agreement may not diminish an employee’s entitlement to:

  • Compensation for total or partial disability.
  • Temporary disability compensation.
  • Medical treatment that is fully paid by the employer as required by workers’ compensation law.

Any portion of an agreement that unlawfully diminishes these entitlements is null and void.*

The parties may negotiate how medical benefits and disability compensation are delivered, but the authorization to change delivery procedures is not authorization to eliminate the underlying entitlement.

It does not remove California law from the claim

The ADR Program remains grounded in California workers’ compensation law. It may modify procedures only within the authority granted by Section 3201.5 and the governing collective bargaining agreement.

The PIPE Trust ADR Rules incorporate numerous provisions of Division 4 of the Labor Code and direct arbitrators to apply California statutory and decisional law except where the Program has made an authorized modification.

It does not eliminate formal adjudication

The ADR Program emphasizes early and informal problem-solving, but a party is not required to accept an unresolved or unacceptable result merely because the matter was presented to the Ombudsman or a mediator.

Unresolved disputes may proceed to arbitration, where evidence can be presented and a binding decision can be issued.*

It does not eliminate outside review

An ADR Program arbitrator is not the final source of legal review. Arbitration decisions remain subject to reconsideration by the Workers’ Compensation Appeals Board and subsequent appellate review in the manner prescribed by California law.

It does not apply to everyone or every employer

California Labor Code Section 3201.5 applies only to qualifying private employers or employer groups in specified industries, working with a recognized or certified exclusive collective bargaining representative. Employers or employer groups must also satisfy statutory insurance-premium, self-insurance, licensing, documentation, and administrative eligibility requirements.

The ADR Program therefore cannot be imposed unilaterally by an individual employer, insurer, or claims administrator.*


How the ADR Program may benefit an injured employee

A work injury can create uncertainty about medical care, income, employment, and the future. The employee may be trying to recover physically while also receiving unfamiliar letters, medical reports, benefit notices, and requests for information.

The ADR Program is intended to give a covered injured employee a more accessible place to begin when something does not appear to be working properly.

A dedicated source of assistance

Instead of requiring the employee to determine immediately which agency, form, attorney, or court procedure might apply, the employee can contact the Office of the Ombudsman with a question or unresolved concern.

The Ombudsman can help identify the issue, contact the appropriate claim participant, obtain relevant information, and explain available ADR Program options.

An opportunity to resolve problems before litigation

Many disputes can arise from missing records, unanswered correspondence, differing understandings, or a failure to connect the correct people. Ombudsman involvement and mediation create opportunities to correct these problems without the expense, delay, and adversarial nature of formal litigation.

Resolution is not guaranteed, but the ADR Program is structured to make a meaningful effort before requiring a formal hearing.

A system familiar with the covered industry

The ADR Program was collectively bargained for employees and employers in the plumbing and piping industry. Its labor-management oversight structure allows the Program to consider the needs of the covered workforce, participating contractors, and the realities of construction employment.

Joint oversight of providers and Program professionals

The Joint Labor Management Safety Committee approves the medical and dispute-resolution professionals used by the ADR Program. This gives both labor and management a role in Program governance rather than leaving the system under the unilateral control of either side.

Preservation of formal rights

The ADR Program’s emphasis on communication and resolution does not eliminate formal adjudication. An unresolved dispute may be decided by an arbitrator, and the arbitrator’s decision remains subject to the review provided by California law.*

Most importantly, Labor Code Section 3201.5 does not authorize the collective bargaining parties to diminish the injured employee’s entitlement to the workers’ compensation benefits protected by the statute.


Benefits for other ADR Program stakeholders

Participating employers

The ADR Program can provide employers with a defined process for identifying claim problems, improving communication, and addressing return-to-work issues. Earlier clarification may reduce uncertainty, prevent misunderstandings from escalating, and help the employer remain involved in appropriate modified-duty or return-to-work planning.

Labor organizations

Union participation in Program governance gives labor a continuing role in the selection of providers, oversight of the ADR structure, and evaluation of how the system serves covered members.

Insurance carriers and claims administrators

The Office of the Ombudsman provides claims professionals with a consistent point of contact for addressing communication failures and identifying the specific issue preventing a claim from moving forward. Mediation may also help narrow disputes before the parties incur the cost of formal proceedings.

Medical and service providers

An agreed provider structure can create clearer communication channels and greater familiarity with Program requirements, the covered trades, and the physical demands of plumbing and pipefitting work.

The Joint Labor Management Safety Committee

The ADR Program allows the Committee to evaluate recurring claim, medical, safety, and return-to-work issues from both labor and management perspectives. That information may help the Committee improve its administration and identify broader opportunities for injury prevention.
