The short answer is: employer healthcare costs are generally higher in unionized workplaces than in non-union workplaces, but the cost difference is often accompanied by richer benefits, lower employee cost-sharing, and greater plan stability. This is not a simple good-versus-bad comparison. Both models have distinct trade-offs that affect total compensation, workforce satisfaction, and long-term budgeting.
What the data shows
Analyses from the Bureau of Labor Statistics (BLS), the Employee Benefit Research Institute (EBRI), and peer-reviewed studies of employer-sponsored coverage consistently find that unionized employers pay more for health benefits. Key figures include:
- Higher employer costs per hour worked: BLS Employer Costs for Employee Compensation data show union employers paid $6.42 per hour worked for health insurance versus $2.31 for non-union employers in June 2021. Total benefit costs in June 2025 ran $22.19 per hour for union workers versus $14.40 for non-union workers, with health insurance a major driver of the difference.
- Lower out-of-pocket costs: Union workers pay a smaller share of their healthcare spending out of pocket, about 26% in one Medical Expenditure Panel Survey analysis spanning 1996 to 2019, and union plans tend to carry lower deductibles.
- Higher coverage rates: Union workers are far more likely to have employer health coverage at all, 98% versus 86% for non-union workers, and more likely to have a regular care provider (83% versus 74%).
Why are union healthcare costs higher?
Collective bargaining drives richer benefits
Unions negotiate healthcare as a core part of total compensation. They prioritize lower deductibles, broader networks, and better coverage for dependents, often accepting slower wage growth in exchange. This is a deliberate trade-off: in many union contracts, wages grow more slowly while benefits stay richer.
Less reliance on cost-shifting
Non-union employers, especially in competitive industries, increasingly shift costs to employees through high-deductible plans and HSAs. Union contracts have historically resisted that shift, and union workers still pay lower premiums for family coverage and a smaller out-of-pocket share, according to Georgetown's Center on Health Insurance Reforms. The gap is narrowing, though: by March 2024, HSA access had reached 40% of union workers and 39% of non-union workers, according to BLS.
Administrative and plan design complexity
Union plans often involve multi-employer (Taft-Hartley) trusts or union-management joint trusteeship, which adds administrative layers. These structures sometimes yield economies of scale through pooled risk across many small employers, but they also carry their own fixed administrative costs.
Are there offsetting savings?
Higher employer cost per employee doesn't always mean a worse bottom line for unionized employers. Several factors can partially offset the premium difference:
- Lower turnover and training costs: Stable union workforces reduce the need to continuously onboard new employees. Replacing a worker costs 50% to 200% of annual salary depending on role, according to SHRM and Gallup.
- Greater preventive care use: Union workers visit office-based providers 31% more often than non-union workers and are more likely to have a regular provider, which can catch treatable conditions earlier.
- Reduced absenteeism: Better access to healthcare can mean fewer missed days for treatable conditions.
Real-world example: manufacturing vs. retail
Industry mix matters as much as union status. About 75% of manufacturing firms offer health insurance versus 48% of retail firms, according to KFF data cited in the medical literature. Within manufacturing, union workers' total compensation averaged $52.54 per hour worked in June 2025 versus $45.42 for non-union workers, with benefits accounting for most of the gap. A unionized manufacturer tends to pair strong coverage with a benefit-heavy cost structure, while a retailer is less likely to offer coverage at all.
Separating union status from industry mix
The headline gap overstates what bargaining alone does. Union workers are concentrated in manufacturing, public service, and larger establishments, where benefits are richer for everyone, so a raw union-versus-non-union comparison partly measures industry composition. The economics literature reflects this: Freeman and Medoff found in 1984 that union employers paid a 14% higher share of premiums, and Even and MacPherson found that advantage narrowed between 1983 and 1988. When benchmarking a unionized competitor, compare against non-union employers in the same industry and size band, not the workforce as a whole.
What this means for employers
If you are evaluating unionization or benchmarking your benefits against union competitors, consider these points:
- Model total compensation, not just health costs. Union workers may trade cash wages for richer benefits, so compare total cost (wages plus benefits plus payroll taxes) to understand the true financial impact.
- Negotiate plan design strategically. Even in a non-union setting, you can offer a low-deductible PPO option alongside an HDHP to attract workers who value stability.
- Use wellness and preventive care to manage long-term risk. Unionized employers often incentivize preventive care; the same strategies work in non-union plans to reduce severe claims.
- Be transparent about cost versus value. Communicate clearly what employees pay and what they get. This reduces dissatisfaction and turnover regardless of union status.
The bottom line
Employer health costs run higher in unionized workplaces: union benefit costs averaged $22.19 per hour worked versus $14.40 for non-union workers in June 2025, with health insurance a major driver of the gap. Part of that difference reflects where union workers are concentrated rather than unionization alone. Union workers also use more care, pay less out of pocket, and turn over less, so the higher employer cost is not a simple loss. The useful benchmark for any employer, union or not, is value per dollar spent: plans that support employee health, retention, and financial stability.
