Multi-employer plans defined
A multi-employer plan is an employee benefit plan to which more than one employer is required to contribute, where contributions are made under one or more collective bargaining agreements between the employers and one or more labor organizations. The plans are commonly called Taft-Hartley plans, after the Labor Management Relations Act of 1947 that established the legal framework for them. They cover construction trades, hospitality, transportation, healthcare, entertainment, and many other sectors where workers move between employers within a defined craft or industry.
For ERISA purposes, multi-employer plans are subject to all the same fiduciary duty rules, reporting obligations, and bonding requirements as single-employer plans. Section 412 applies in full. The bonding analysis is at the plan level — the plan as a whole is bonded, not each contributing employer separately, not the union as an institution, and not the individual trustees.
- Multi-Employer Plan
- An employee benefit plan jointly maintained by multiple employers and one or more labor organizations under collective bargaining. Subject to ERISA, governed by a joint board of trustees, and bonded under Section 412 in the same manner as single-employer plans.
- Taft-Hartley Plan
- The common term for multi-employer welfare and pension plans created under section 302 of the Labor Management Relations Act of 1947. The Act requires that any contributions to a multi-employer fund be held in trust under a board of trustees with equal representation from the employer side and the labor side.
- Joint Board of Trustees
- The governing body of a Taft-Hartley plan, with equal numbers of trustees representing the contributing employers and the represented labor organizations. All trustees are fiduciaries under ERISA Section 3(21).
- Withdrawal Liability
- The financial obligation an employer incurs upon ceasing participation in a multi-employer pension plan. Not directly relevant to bonding but important context for trustees evaluating the plan's overall risk profile.
The joint trustee structure
The defining feature of a Taft-Hartley plan is its dual governance. Equal numbers of employer-appointed trustees and union-appointed trustees jointly administer the plan, vote on benefit levels and investment policy, and bear identical fiduciary duties under ERISA. Neither side dominates; deadlocks are typically broken by an arbitrator selected by the parties or specified in the plan documents.
For bonding, the consequence is that all the trustees — both sides — handle plan funds and must be bonded. The bond is written on a blanket basis covering the trustee positions, so individual trustee turnover does not require endorsement. New trustees stepping onto the joint board are automatically covered as of their start date, exactly as in a single-employer plan.
Who must be bonded
The persons typically bonded on a multi-employer plan include:
- All members of the joint board of trustees — both employer-side and union-side
- The plan administrator and any delegated representatives
- Officers and employees of the plan office with disbursement authority
- The fund's investment committee members who direct trades
- Third-party administrators handling contributions and distributions, where not exempt
- The fund's collection counsel and benefits counsel if they handle funds
The union staff who handle dues collection or member services do not need to be bonded under the plan's ERISA bond — they are union employees, not plan fiduciaries, and the ERISA bond covers plan funds, not union funds. Union dues bonding is a separate inquiry under different rules (see below).
Sizing the bond
The Section 412 formula applies to multi-employer plans the same way it applies to single-employer plans. The bond must equal at least 10% of the plan funds handled by the bonded persons during the preceding plan year, subject to the $1,000 minimum and $500,000 maximum (or $1,000,000 if the plan holds employer securities — uncommon for Taft-Hartley plans, but possible for jointly trusteed ESOPs).
The "plan funds handled" calculation is performed on the plan as a whole, not on the contributions of individual employers. A plan that received $20,000,000 in employer contributions over the prior year requires a bond of $2,000,000 — well above the standard cap, so the bond is written at $500,000 (or higher, if the trustees elect coverage above the cap as the DOL recommends).
Carry above the cap when warranted.
For large multi-employer plans whose 10% calculation would produce a figure well above the $500,000 cap, the DOL strongly recommends carrying coverage at the calculated amount rather than at the statutory ceiling. Trustees who limit coverage to the cap when the calculation would produce far more are technically compliant but may face fiduciary breach exposure if a large loss exceeds the bonded amount.
Bonding the union itself
An ERISA fidelity bond covers the benefit plan, not the labor organization that participates in maintaining the plan. Unions have their own separate bonding obligations under the Labor-Management Reporting and Disclosure Act of 1959 (LMRDA), which requires every union officer or employee handling union funds to be bonded under 29 U.S.C. § 502.
The two bonds are distinct. The ERISA bond protects the benefit plan from dishonesty by persons handling plan funds. The LMRDA bond protects the union from dishonesty by union officers handling union funds (dues, treasury, organizing budgets). Many of our union clients carry both, and we write both — though the LMRDA bond is administered through a separate intake. Call (800) 373-2804 to discuss.
| Coverage | Statute | What It Protects | Bonded Amount |
|---|---|---|---|
| ERISA bond | 29 U.S.C. § 1112 | The benefit plan | 10% of plan funds handled, capped at $500K / $1M |
| LMRDA bond | 29 U.S.C. § 502 | The union itself | 10% of union funds handled, capped at $500,000 |
How to get one
Multi-employer plan bonding follows the same general workflow as single-employer plans, with documentation appropriate to the joint-trustee structure:
- Calculate the bond amount.10% of plan funds handled in the prior year, capped at $500,000 for standard plans or $1,000,000 for plans holding employer securities.
- Gather documentation.Trust agreement, current list of trustees and their employer / union affiliation, most recent Form 5500, plan financial statements.
- Submit the application.Online application with the plan as the named insured, or call (800) 373-2804 directly. Multi-employer plans often benefit from the specialty intake because of the joint-trustee questions.
- Underwriter review.Most multi-employer applications are reviewed by an underwriter familiar with the Taft-Hartley structure. Expect questions about contributing employers, investment governance, and prior bond history.
- Bond issuance.Once premium is received, the executed bond is delivered. Schedule H Line 4e reporting on the plan's Form 5500 records the bond going forward.

Frequently asked questions
Does each contributing employer need its own bond?
No. The bond is at the plan level, not at the contributing-employer level. Each contributing employer is required to pay contributions to the plan as required by the collective bargaining agreement, but the employer's own ERISA bonding obligations apply to its own single-employer plans (if any), not to the multi-employer plan it contributes to.
What happens when a trustee leaves the joint board?
The bond is written on a blanket basis covering trustee positions, so a trustee leaving the board ceases to be covered as of the date of departure, and the replacement trustee is automatically covered as of the date of appointment. No endorsement is required for routine trustee turnover, which is common in multi-employer plans where trustees rotate per the parties' practices.
Can a multi-employer plan use the standard online application?
Yes for compliant standard placements. The online application accepts multi-employer plans as long as the plan answers "no" to the three eligibility questions (non-qualified assets, employer securities, prior loss). Plans with non-standard factors should call (800) 373-2804 directly.
Are pension plans and welfare plans bonded separately?
Generally yes — most Taft-Hartley structures maintain separate trusts for pension and welfare plans, with separate Form 5500 filings, separate Schedule H reports, and separate bonds. A few funds use a combined trust for both; that structure is more complex from a bonding perspective and should be discussed with our underwriters.
What if a contributing employer goes bankrupt?
The fact does not affect the plan's bond requirement. The bond covers losses to the plan from dishonesty by persons handling plan funds; an employer's bankruptcy is a contribution-collection issue (and potentially a withdrawal-liability issue), not a bonding issue. The bond continues to cover the plan as it has been doing.
