NCCI’s May 2026 Labor Market Insights report shows employment growth accelerated to an average of 76,000 jobs per month in early 2026, up from 10,000 per month in 2025. April alone added 115,000 nonfarm jobs (123,000 in the private sector), breaking an 11-month streak of alternating gains and losses. For self-insured employers carrying WC retention, the acceleration means payroll exposure bases are moving faster than last year’s actuarial projections assumed.
The growth is concentrated in sectors that carry above-average WC claim frequency. Healthcare led April’s hiring at 37,000 jobs, above its 32,000 monthly average over the prior year. Transportation and warehousing added 30,000. Retail, leisure and hospitality, and other services all contributed to the early-2026 rebound. These are not low-hazard office classes; they include warehouse operations, patient handling, commercial driving, and trades work where injury rates run two to five times the all-industry average.
Who it affects
Self-insured employers in healthcare, construction, transportation, and hospitality who have been adding headcount in 2026. State and municipal pools with exposure in public works, transit, and corrections. Group captives and risk retention groups whose members operate in high-hazard classes. Any WC program whose mid-year payroll is running materially above the figure used in the latest reserve study.
The reserve mechanism
Payroll is the exposure base for WC reserving. When payroll rises, expected claim counts increase even if frequency rates hold constant. NCCI’s 2026 State of the Line reported 2025 payroll growth of approximately 5%, driven almost entirely by wage increases rather than headcount. The 2026 data shifts the composition: headcount is now contributing alongside wages, which increases both the number of workers exposed and the indemnity benefit base that drives per-claim severity.
The timing matters. NCCI’s accident year combined ratio hit 102% in 2025, meaning the WC system is already consuming more in current-year losses than it collects in premium. More workers entering a system operating above breakeven widen the gap unless frequency continues to decline at historical rates. But lost-time claim frequency fell only 2% in 2025, the most modest decrease in years. If that flattening continues into a higher-employment 2026, the frequency tailwind that compressed WC loss costs for more than a decade may be stalling.
Wage acceleration adds a second channel. Rising average hourly earnings increase indemnity benefits for every new claim, and they inflate the statutory benefit calculations on open claims in states that index weekly maximums. Self-insured programs that selected indemnity severity trend assumptions before the 2026 hiring surge should test whether those assumptions still hold.
What this means for your next review
If your organization has added headcount in high-hazard classes in 2026, ask your actuary to update the payroll exposure base before the next IBNR estimate. Most reserve studies use the payroll projection from the prior policy year; a mid-year adjustment prevents a mismatch between projected and actual exposure that shows up as adverse development 12 to 18 months later. Ask specifically whether your frequency trend selection still reflects the 2025 deceleration in the declining-frequency trend, and whether your indemnity severity assumption accounts for accelerating wage growth. These are not hypothetical risks. They are arithmetic: more workers at higher wages, in classes that get hurt more often.
