If you're a union member — whether in construction, transportation, retail, healthcare, entertainment, or another unionized industry — your health benefits may come from a Taft-Hartley multiemployer health and welfare fund. These plans are fundamentally different from both employer-sponsored single-employer plans and individual insurance, and understanding how they work is essential when a claim is denied.

What Is a Taft-Hartley Plan?

Named for the Labor-Management Relations Act of 1947, Taft-Hartley plans (also called multiemployer benefit plans) are health and welfare funds established through collective bargaining between a union and multiple employers in an industry. The plan is funded by contributions from multiple employers under the terms of their collective bargaining agreements.

Key structural features:

• Joint administration: The plan is administered by a board of trustees that is equally divided between union and employer representatives. This joint administration is required by Taft-Hartley law.
• Trust fund structure: Plan assets are held in a trust fund, separate from both the union and any individual employer
• ERISA coverage: Taft-Hartley plans are covered by ERISA — unlike government plans, multiemployer union plans are private-sector ERISA plans
• No single employer: Your employer contributes to the fund, but the fund — not your employer — is the plan

Examples of large Taft-Hartley funds include: UFCW (retail/food), IBT/Teamsters, IBEW (electricians), UA (plumbers), LIUNA (laborers), SAG-AFTRA (entertainment), and hundreds of smaller regional funds.

How Claims Administration Works

Taft-Hartley funds typically administer claims in-house or contract with a third-party administrator. Unlike employer ERISA plans where HR is the first contact, union fund members typically deal directly with the fund office for claims issues.

The board of trustees has broad authority to interpret plan terms, determine eligibility, and decide benefit disputes. This broad discretion is generally upheld by courts under ERISA's arbitrary and capricious standard of review — if the trustees had a rational basis for their decision and didn't abuse their discretion, courts will typically affirm it.

Your ERISA Rights as a Fund Participant

Despite the different structure, your core ERISA rights as a Taft-Hartley participant are the same as any ERISA plan participant:

Right to plan documents (ERISA §102): You're entitled to the Summary Plan Description within 90 days of becoming a participant, and to updated SPDs as the plan changes. Request the SPD from the fund office.

Right to claim file (ERISA Section 503 — Your Rights" class="auto-link">ERISA §503): Upon written request, the fund must provide all documents relevant to your claim — medical necessity criteria, reviewer notes, correspondence — within 30 days.

Right to appeal (ERISA §503): The fund must have an internal claims and appeals procedure. You must receive a written denial with specific reasons, and you have the right to appeal.

Right to External Independent Review: Complete Guide" class="auto-link">external review: ACA requirements apply to ERISA group health plans, including multiemployer plans. Most Taft-Hartley plans are required to provide independent external review for medical necessity and other adverse benefit determinations.

Right to sue in federal court (ERISA §502): After exhausting internal appeals, you can bring a claim in federal court.

Special Considerations for Taft-Hartley Appeals

Trustee deference. Courts generally give trustees of Taft-Hartley plans broad deference under an arbitrary and capricious standard when the plan vests discretionary authority in the trustees. This is why building a complete administrative record during the internal appeal is especially critical — your appeal before the trustees may be your best and most effective forum.

Political dynamics. Because the board of trustees includes both union and employer representatives, your union representatives on the board may be advocates for your claim. Contact your union local for assistance with appeals — union staff representatives are often experienced in fund benefit disputes.

Eligibility disputes. A common issue in multiemployer plans is eligibility — you may have earned the right to benefits based on hours worked for contributing employers, but if your hours fell below the required threshold, you may lose coverage. Eligibility disputes are among the most common issues in multiemployer plans. Review the plan's eligibility rules carefully and check whether hour banks or continuation coverage provisions might apply.

Portability between contributing employers. When you change jobs within the same industry or craft, make sure your hours and contributions are being properly credited to the fund. Payroll reporting errors by new employers are a frequent source of coverage gaps.

Using the DOL for Taft-Hartley Disputes

The DOL Employee Benefits Security Administration (EBSA) has oversight authority over Taft-Hartley plans as ERISA plans. You can file complaints with EBSA for:

• Procedural violations (late decisions, inadequate denial notices)
• Failure to produce plan documents
• Mental Health Parity Act (MHPAEA) Explained" class="auto-link">MHPAEA violations
• Fiduciary breaches

File at dol.gov/ebsa or call 1-866-444-3272.

Your Collectively Bargained Benefits

One additional resource: your collective bargaining agreement. The CBA may specify benefit levels, appeal rights, or other terms that supplement or modify the plan document. Your union business agent or staff representative should have the CBA and can help you understand whether the fund's denial is consistent with the bargained terms.

Fight Back With ClaimBack

Taft-Hartley plan appeals require understanding the fund's specific documents, the trustee structure, and ERISA's procedural framework. ClaimBack helps union members build complete, documented appeals that give trustees a full factual and legal basis for reversing a denial.
