Key Takeaways

• Starting with the 2026 construction cycle, the City of Dayton is requiring Project Labor Agreements on public construction projects over $2 million, and bids have already gone out under this mandate.
• A project labor agreement PLA is a pre-hire collective bargaining agreement that forces all contractors and subcontractors on a covered project to operate under union terms, union hiring hall requirements, and union work rules—regardless of their usual merit shop model.
• Roughly nine out of ten construction workers in the Ohio Valley are nonunion, meaning Dayton’s PLA mandate effectively sidelines the vast majority of the regional workforce and constrains merit shop contractors from deploying their own trained employees.
• ABC Ohio Valley is organizing a focused response: the OVABC PAC Committee is forming a subcommittee dedicated to addressing the Dayton PLA issue and connecting this fight to broader advocacy efforts, including the ABC Legislative Conference 2026.
• The window to influence this policy is open now—before PLAs become embedded practice in Dayton and spread to Cincinnati, Northern Kentucky, and other Ohio Valley public owners.

Why Dayton’s 2026 PLA Mandate Demands Your Attention Now

If you’re a merit shop contractor operating in Dayton, Cincinnati, Springfield, Lima, Northern Kentucky, or Southeast Indiana, this is the intelligence briefing you need to read before your next bid meeting. Beginning with construction projects advertised for bid in late 2025 with 2026 start dates, the City of Dayton has begun requiring government-mandated PLAs for publicly funded projects exceeding $2 million in total value. This isn’t a rumor or a policy proposal—it’s happening right now. The requirement attaches to every contractor and subcontractor performing work on a covered project. That means mechanical, electrical, site work, and specialty trades—not just the prime contractor. Multiple Dayton projects have already been advertised with PLA language embedded in the bid documents, with more expected as the city updates its capital improvement and facilities plans. For merit shop firms, this creates immediate hard choices:

• Do you bid under terms that force your workforce through a union hiring hall?
• How do you price risk you’ve never carried before?
• Can you even staff the job under these constraints?

The stakes extend beyond one city’s public works portfolio. If Dayton’s mandate proceeds unchallenged, it creates a template that Cincinnati, Northern Kentucky, and other local governments could adopt. Loss of market access, disrupted workforce models, and long-term erosion of merit shop competitiveness are all on the table.

What Is a Project Labor Agreement? (PLA Basics)

A project labor agreement is a pre-hire collective bargaining agreement between one or more labor unions and a project owner or contractor. Such an agreement establishes the terms and conditions of employment for a specific construction project before any worker is hired. Under a typical government-mandated project labor agreement, all contractors and subcontractors performing work on the covered project must agree to be bound by the PLA’s terms as a condition of bidding and award. This applies whether your firm is union-signatory or merit shop—once you sign on, you’re operating under union rules. Here’s what that means in practical terms:

PLA Element	What It Requires
Wages & Benefits	Employment conditions—wages, benefits, hours, overtime rules, grievance procedures—are dictated by union collective bargaining agreements incorporated into the PLA
Labor Peace Clauses	No-strike, no-lockout provisions and mandatory arbitration for disputes
Hiring Requirements	Contractors must route hiring through union hiring halls before using their own existing employees, particularly for core trades
Jobsite Access	Union stewards and business agents receive broad access rights to the site and workforce, including authority to enforce union work rules and jurisdiction
Dues & Fees	Nonunion employees working on the project may be required to pay union dues, initiation fees, or agency fees for the duration of the job, depending on state law

PLAs trace back to the 1930s, and their legality under the National Labor Relations Act has been litigated and upheld. But legal permissibility is separate from business impact. The question for Ohio Valley contractors isn’t whether government entities can impose project labor agreements—it’s what happens to your business when they do. The focus of this article is on the business impact: what a project manager or estimator needs to know when they open a bid package and find PLA language in the spec section.

How Dayton’s PLA Requirement Works in Practice

Dayton’s policy represents a shift from open competition to mandated pre-hire union agreements for taxpayer-funded construction projects exceeding $2 million. This affects schools, public buildings, infrastructure, and facilities across the city’s capital portfolio. When a Dayton PLA clause appears in bid documents, it typically requires the successful bidder to enter into a labor agreement approved by the City of Dayton that covers all on-site construction labor. Once the prime contractor signs that PLA, the obligation cascades:

• Subcontractor assent is mandatory: Every sub—whether local or out-of-market, union or merit shop—must sign “letters of assent” agreeing to be bound by the PLA as a condition of working on the project.
• Company policies take a back seat: Existing employment policies, safety programs, and HR procedures must be reconciled with the PLA’s union work rules.
• Crew control shifts: Crew assignment, foreman selection, and job classifications may be subject to union jurisdiction and to job descriptions rather than company practice.
• Compensation follows union scales: Overtime, shift differentials, and holiday pay follow union provisions embedded in the PLA—not your standard compensation structure.

Timeline orientation: This applies to projects subject to bids advertised in late 2025 and beyond, with construction beginning in 2026 and later.

Hypothetical Example: Dayton School Renovation

Consider a hypothetical Dayton school renovation project valued at $3.5 million. A merit shop general contractor wins the bid but must sign the city-approved PLA. Here’s what happens:

1. The GC must route 80%+ of hiring through union halls
2. Union wage scales ($40-60/hr for crafts) apply instead of the contractor’s established rates ($30-45/hr)
3. Electrical, mechanical, and specialty subs must sign letters of assent or decline the work
4. Union stewards gain site access to enforce work rules
5. The contractor estimates a 12-15% bid premium to cover unfamiliar costs and risks

Some subcontractors may decline to work under these conditions, shrinking the pool and potentially requiring the GC to bring in union-signatory firms from outside the market.

Why PLAs Clash with the Merit Shop Model

ABC Ohio Valley represents contractors who compete and succeed based on quality, safety, productivity, and price—not mandated union status. That’s the merit shop philosophy, and it’s how nine out of ten construction projects in this region get built. Government-mandated PLAs create fundamental conflicts with how merit shop firms operate: Loss of workforce control: Hiring decisions, crew composition, and promotion pathways become subject to union hall referrals and seniority rules rather than to company evaluations and project needs. You lose the ability to deploy your best people where you need them most. Inability to fully deploy your own trained employees. Long-term nonunion team members—the workers you’ve invested in through training, safety certification, and career development—may be boxed out or forced to work under unfamiliar union rules and benefit plans. Disruption of existing benefits and retirement plans, duplicative or competing fringe requirements under PLAs, complicate compliance with company-level health and retirement programs. On short-term projects, union pension contributions may never vest, creating stranded costs. Changes to safety culture and workflow. Company-developed safety programs and lean practices may collide with rigid union jurisdiction and inefficient union work rules that limit productivity. For many mid-sized and family-owned firms across the Ohio Valley, the merit shop model isn’t just a preference—it’s the foundation of their training investments, productivity systems, and cost structure. Entering even one PLA project can strain relationships with long-time employees who expect nonunion work conditions and merit-based advancement.

Regional Labor Reality: Who Actually Builds the Ohio Valley?

Policy discussions about PLAs often overlook a basic fact: the actual construction workforce doesn’t align with the model these mandates impose.

Approximately 90% of construction workers in the broader Ohio Valley region—Ohio outside a few urban cores, Northern Kentucky, Southeast Indiana—are not members of a building trades union.

This isn’t speculation. U.S. Bureau of Labor Statistics data shows 88.5% of U.S. construction workers were nonunion in 2023, with regional patterns in the Ohio Valley similar or even more pronounced due to right-to-work influences in parts of Kentucky and Indiana. At the same time, the Ohio Valley faces an estimated shortage of around 60,000 skilled workers over the next several years. This gap is driven by:

• Retirements (national average construction worker age: 42.9)
• Infrastructure demand from federal aid highway projects and IIJA funding
• Private-sector investment and development

Forcing public work through union hiring halls under PLAs narrows the labor funnel to roughly 10% of the available workforce. This worsens shortages and frustrates efforts to meet project schedules. ABC Ohio Valley’s investments in workforce development and registered apprenticeship demonstrate how the merit shop sector actively expands the talent pipeline—without requiring union membership. Nationally, ABC apprenticeship programs start over 10,000 new apprentices annually. Dayton’s PLA policy prioritizes a minority labor model over the majority that already delivers the bulk of commercial, industrial, and infrastructure work across the region.

Business Impacts: Competition, Cost, and Market Access

PLAs reshape how work is awarded, priced, and delivered. For merit shop construction contractors and taxpayers alike, the consequences are significant.

Competition Effects

When government agencies impose project labor agreements on publicly funded projects, the bidder pool shrinks:

• Many nonunion contractors either decline to bid under PLA conditions or bid less aggressively due to unfamiliar risk
• Minority contractors and women-owned firms without established union relationships face higher barriers to entry
• Reduced competition typically leads to higher bid prices, particularly those in the $2-10 million range, where local merit shop firms normally compete fiercely

Cost and Risk from the Contractor’s Perspective

Cost Factor	Impact
Labor costs	Compliance with union wage rates and benefit packages can increase labor cost inputs 20-30% above merit shop rates
Administrative overhead	New fringe reporting, benefit remittances, and grievance procedures add compliance complexity and legal risk
Stranded costs	Short-term work under a PLA often creates non-vesting pension contributions and duplicative benefits that don’t translate back to company plans
Pricing uncertainty	Unfamiliar work rules and regulations governing safety procedures require padding bids to cover unknown risks

Market Access

Merit shop firms that decide not to work under PLAs lose access to Dayton’s entire portfolio of public construction projects over $2 million—schools, public buildings, affordable housing projects, and infrastructure. For as long as the mandate remains, this revenue shifts toward union contractors and out-of-area firms that regularly work under PLAs. National and regional research cited by Associated Builders and Contractors has documented that government-mandated PLAs often raise construction costs 10-20% without delivering measurable schedule or quality advantages. Studies from the Beacon Hill Institute and Rand Corporation have found no net efficiency gains from PLAs on schools and public facilities.

Policy Narratives vs. On-the-Ground Reality

Government officials and labor organizations promoting PLAs typically position them as tools to:

• Promote local hiring and support local workers
• Improve diversity in the construction workforce
• Guarantee producing labor management stability
• Streamline delivery on large, complex projects

These claims deserve scrutiny in the Ohio Valley context. On local labor: Routing work through union hiring halls does not guarantee local residents get jobs. Hiring prioritizes union membership rolls, which may or may not reflect Dayton-area workers. Trade unions often dispatch from regional or national pools based on availability rather than geography. On diversity and equal employment opportunity: Women-owned and minority contractors who operate as merit shop firms often lack regular union relationships. PLA conditions effectively sideline these businesses from competing. National minority business organizations have raised similar concerns about how mandates limit opportunities for non-union workers and non-union contractors alike. On labor-management stability and efficiency: High-profile PLA projects across the country—including California high-speed rail—have missed local hiring and diversity targets despite community workforce agreements. Research has linked mandated project labor agreements to cost increases on schools, public facilities, and federally funded construction projects without producing corresponding schedule or quality improvements. ABC’s position is clear and longstanding: ABC Ohio Valley opposes government-mandated PLAs not out of hostility to construction unions, but because these mandates restrict open competition, sideline the merit shop workforce, and undermine taxpayers’ interest in achieving economy through best-value, performance-based contracting. From the perspective of the region’s merit shop majority, PLAs are not a neutral administrative tool. They are a mechanism that shifts union control over the workforce and projects away from the contractors who build nine out of ten projects subject to competitive bidding.

ABC Ohio Valley’s Response: Organizing Before This Becomes Permanent

ABC Ohio Valley is moving early and deliberately to respond to Dayton’s PLA mandate—before it becomes embedded practice and spreads across the region.

OVABC PAC Subcommittee on Dayton PLAs

The OVABC PAC Committee is forming a dedicated subcommittee focused specifically on the Dayton PLA issue. This subcommittee is being organized in 2026 with a focused mission:

• Analyze Dayton’s PLA policy and its impact on member firms
• Engage city leadership and relevant government entities
• Protect open competition for taxpayer-funded projects over $2 million
• Develop both short-term and long-term strategies

The subcommittee will draw from member contractors, legal and policy experts, and ABC Ohio Valley staff.

Lines of Action

Potential strategies under consideration include:

• Monitoring and analysis: Tracking specific Dayton PLA projects to quantify competitive and cost impacts with real data
• Public engagement: Coordinating member testimony and documentation for council meetings, public hearings, and local media coverage
• Legal and legislative avenues: Exploring appropriate challenges in coordination with ABC National and the broader federal procurement policy team
• Coalition building: Connecting with other construction users, minority contractors, and taxpayer groups concerned about government neutrality in contracting

The goal is to prevent Dayton’s model from becoming the default for other public owners in Cincinnati, Northern Kentucky, Springfield, Lima, and Southeast Indiana. Merit shop voices need to be present early—before policies are set and precedents established.

How Merit Shop Contractors Can Engage Right Now

You’re busy. Bids are due, jobs are running, and you’ve got a hundred decisions to make this week. But this issue affects your backlog, your workforce, and your long-term business plans. Here’s what you can do right now:

Concrete Next Steps

1. Join the PAC Subcommittee: Contact ABC Ohio Valley to join or nominate someone from your leadership team for the OVABC PAC subcommittee on Dayton PLAs. Reach out to ABC Ohio Valley’s advocacy team to get involved.
2. Download the ABC Action App: Get timely alerts on PLA-related developments in Dayton and across the region. When calls for comments or outreach go out, you’ll be able to respond quickly.
3. Support the Free Enterprise Alliance: ABC’s Free Enterprise Alliance funds grassroots campaigns, digital outreach, and coalition-building to oppose PLA mandates at the local, state, and federal levels. Financial support makes this work possible.
4. Engage Your Peers: Talk to contractors in your network—particularly those who haven’t been active in advocacy. Explain how the Obama administration-era executive order encouraging PLAs has now evolved into local mandates that expose contractors to real market exclusion. The more voices, the stronger the response.

Connect to the Broader Fight

This Dayton PLA fight connects to the broader merit shop advocacy agenda. The ABC Legislative Conference 2026 serves as the hub for federal projects, federal contracts, and federal agencies’ policy discussions—including opposition to federal construction projects mandates under Executive Order 14063 and beyond. Nine out of ten construction projects in this region are built by the open-shop workforce. Protecting open competition protects the region’s economic engine.

The window to shape Dayton’s PLA trajectory—and to prevent its spread to other Ohio Valley public owners—is open now. But it will narrow as more PLA projects proceed unchallenged.

Frequently Asked Questions about Project Labor Agreements in Dayton

Can my nonunion company bid on a Dayton PLA project and still use our own employees?

In most PLA structures, including those modeled by large municipalities like Dayton, contractors must first seek workers through union hiring halls before using their own existing nonunion employees. Some PLAs allow a limited number of “core employees”—typically capped at 10-20% of the workforce—but these positions are still subject to union dispatch oversight. This can significantly disrupt your normal crew structure and project staffing. Before assuming you can staff a particular project primarily with your current workforce, carefully review each Dayton PLA’s specific language with experienced counsel and ABC Ohio Valley.

Does working under a PLA permanently unionize my company?

No. Signing a project-specific PLA or letter of assent does not, by itself, convert a merit shop contractor into a union-signatory company for all work. The obligations created by pre-hire agreements are typically limited to the duration and scope of that particular project. However, PLAs can have significant operational and legal implications while the job is active. Consult with experienced labor counsel and ABC Ohio Valley before entering into any PLA to understand collateral risks, including potential bargaining obligations or precedent for future projects. You do not have to accept union representation permanently to work under a project-specific PLA.

How will Dayton’s PLA mandate affect small and minority-owned merit shop firms?

Smaller, women-owned, and minority-owned merit shop contractors often lack established relationships with union halls and may face higher administrative and compliance barriers under PLAs. The requirement to pay union dues and navigate union apprenticeship programs and hiring procedures creates obstacles that larger, established union contractors don’t face. National minority business organizations have criticized government-mandated PLAs for raising costs and limiting opportunities for nonunion employees and minority contractors who have built successful businesses outside the union framework. If you’re experiencing these impacts, connect with ABC Ohio Valley to document and communicate them to policymakers.

Are PLAs required on all public projects in Dayton or only certain ones?

The City of Dayton’s current policy focuses on public construction projects above $2 million in total value—not every small capital or maintenance job. Projects under the threshold may still follow traditional open competition models without PLAs. The concern is that thresholds can change or policies can expand if left unchallenged. Review each city solicitation carefully and contact ABC Ohio Valley whenever PLA language appears in a bid package so trends can be tracked across the region.

What resources does ABC Ohio Valley offer to help me navigate PLAs?

ABC Ohio Valley provides multiple forms of support:

• Policy briefings for leadership teams on PLA mechanics and implications
• Sample bid language review to help you understand specific requirements
• Connections to legal experts experienced in prevailing wage laws and labor and employment standards
• Updates through chapter newsletters and the ABC Action App
• Advocacy coordination tied to events like the ABC Legislative Conference 2026

Whether you’re a member or not, reach out early. Coordinated response improves the whole region’s ability to address PLA mandates effectively—before they become the default on every publicly funded project in the Ohio Valley.
