Multiemployer Plan
A pension plan maintained by two or more unrelated employers under a collective bargaining agreement, common in construction, trucking, and entertainment.
Multiemployer Plan is a term from U.S. pension regulation and actuarial practice — typically a line item on IRS Form 5500, a concept in actuarial valuations, or a federal pension-insurance term from PBGC rules. The definition here is the practical participant-facing meaning, anchored in how the term actually appears in the data this site uses. Understanding Multiemployer Plan is part of reading pension data defensibly. The underlying technical definition matters less than the participant-relevant interpretation: does this concept signal funded-status pressure, benefit-modification risk, or routine actuarial bookkeeping?
Each plan page on PensionWatch surfaces the Multiemployer Plan-relevant numbers for that specific plan, so the general definition here translates into concrete data on the per-plan pages you actually use.
In Detail
Multiemployer pension plans, also called Taft-Hartley plans, are collectively bargained retirement plans that cover workers across multiple employers in the same industry. They are most common in industries with mobile workforces like construction, trucking, mining, entertainment, and retail. Roughly 1,400 multiemployer plans cover about 11 million workers and retirees. These plans allow workers to change employers within the industry while continuing to build retirement benefits under a single plan.
However, multiemployer plans face unique financial challenges. When one participating employer goes bankrupt, its pension obligations shift to the remaining employers, creating a cascading effect. If enough employers withdraw, the plan can enter a "death spiral" where each departure increases costs for remaining employers. About 130 multiemployer plans covering 1.3 million participants were classified as "critical and declining" status before the American Rescue Plan Act of 2021 provided emergency assistance.
Multiemployer plans have different PBGC guarantee levels than single-employer plans, the maximum guarantee is significantly lower, at roughly $12,870 per year for a participant with 30 years of service, compared to $81,000 for single-employer plans.
