If a pool crew member is injured in a monopolistic state — North Dakota, Ohio, Washington, or Wyoming — workers comp comes only through a government-run state fund, not a private policy, and the injured worker’s benefits flow through that fund. The catch most contractors miss is the employers-liability gap the fund leaves behind.
If you want the overview of what workers comp does and where these four states fit, our workers compensation page covers it. This post goes narrower: it follows an injured pool crew member through the state-fund system and into the gap the fund leaves — the part that turns a contractor’s reasonable assumption into a costly surprise.
The short answer: the fund, not a private policy
In forty-six states, you buy workers comp from a private carrier. In four — North Dakota, Ohio, Washington, and Wyoming — you cannot. These are the monopolistic states, where private carriers are barred from writing comp and an employer obtains coverage only through a government state fund. So when a pool crew member is hurt in one of these four, the question is not “which carrier responds” — it is “is the operation properly registered with the state fund,” because the fund is the sole source of the coverage. That single fact reshapes everything downstream: where you get coverage, who administers the injured worker’s benefits, and what gaps you have to close on your own. A multi-state pool contractor who treats these four like every other state is setting up exactly the surprise this post exists to prevent.
How the injured worker is actually covered
Walk it from the injured crew member’s side. A tech is burned handling chemicals, hurt in a trench, or injured lifting equipment on a job inside one of these four states. The medical care and wage-replacement benefits they receive are administered by the state’s government program — North Dakota’s Workforce Safety & Insurance (WSI), the Ohio Bureau of Workers’ Compensation (BWC), Washington’s Department of Labor & Industries (L&I), or Wyoming’s state fund — rather than by a private carrier. For the worker, the benefits are similar in purpose to private-market comp: this is still a no-fault system designed to cover work-related injury. What differs is the plumbing behind it. The employer’s job is to be properly registered and in good standing with that fund so the worker’s claim is administered cleanly. When that registration is in place, the injured crew member’s path runs through the government program the way it would run through a carrier in a private-market state — same purpose, different source.
Real-World Scenario: A pool construction company based in a private-market state takes a job that runs a crew across the line into one of the four monopolistic states. A worker is hurt on that job. The owner reaches for the private comp policy that covers the crews at home, assuming it follows the work — and learns it cannot respond there, because in that state the state fund is the only source of comp by law. The injured worker’s benefits have to come through the fund the company was never registered with. Nothing about the injury was unusual; the surprise was geographic. The coverage the company relied on simply stopped at a state line it did not know was special.
The employers-liability gap the fund leaves open
Here is the part that catches even contractors who know the state fund exists. The monopolistic funds generally provide the workers comp benefits — but they typically do not include employers liability. Employers liability is the piece of a normal comp policy that responds to certain injury-related suits that fall outside the no-fault system. In a private-market state, it usually rides along inside the comp policy, so contractors rarely think about it. In a monopolistic state, the fund covers the benefits and leaves that employers-liability piece out, which means a contractor who registers with the fund and assumes they are fully protected has a hole they cannot see until a suit arrives to find it. This is not a small footnote — it is the single most overlooked exposure in these four states, precisely because the rest of the system looks like it has everything handled.
Stop-gap employers liability: filling the hole
The fix has a fittingly literal name. Stop-gap employers liability is coverage that fills the employers-liability hole the monopolistic funds leave open — it stops the gap between what the state fund provides and what a full private-market comp policy would have included. Because the funds cover the comp benefits but not employers liability, contractors operating in these states commonly add a stop-gap endorsement to another policy so that an injury-related suit outside the no-fault system has something to respond to. The important thing is that stop-gap is not automatic. It is a deliberate piece of coverage you confirm is in place, attached to the right policy, before a crew works in one of these states — not something the state fund quietly includes on your behalf. For a pool contractor whose crews cross into North Dakota, Ohio, Washington, or Wyoming, confirming the stop-gap endorsement is in place is the move that turns the fund’s gap from an exposure into a closed loop.
What your private comp does — and does not — reach
It bears stating plainly, because the assumption is so common: your private workers comp policy cannot cover crews working in a monopolistic state. The state fund is the only valid source there, by law, regardless of what private comp you carry elsewhere. A crew that crosses from a private-market state into one of these four is not covered by the policy that protects them at home — that policy stops at the line. This is the trap our companion post on whether comp covers a 1099 subcontractor touches from a different angle: coverage response depends on facts you have to get right in advance, and geography is one of them. For a multi-state pool operation, the discipline is to map where crews actually work and to arrange coverage through the right fund for any job inside the four, rather than assuming a single policy blankets the whole footprint.
The four states, and where to read the local picture
Each of the four monopolistic states administers its own fund, and the registration and operating details differ. If your crews work in any of them, it is worth reading the local picture for that state — our location pages for North Dakota, Ohio, Washington, and Wyoming cover the on-the-ground specifics for a pool contractor in each, and the full locations directory maps where else your operation may touch. The common thread across all four is the same: comp through the fund, employers liability filled separately. The differences are in the administration and the local market around the rest of your stack. Reading the state-specific page before a crew works there is the cheapest way to avoid learning the mechanics from a claim.
The rest of the stack still travels
One clarification worth making: only workers comp is monopolistic in these four states. The rest of your coverage stack still works the way it does everywhere else. General liability for third-party injury, commercial auto for the crews on the road, and contractors equipment for the gear that travels are all private-market coverages that follow your operation across the line — it is specifically the comp piece that has to come through the state fund. So the picture for a crew working in a monopolistic state is a hybrid: comp through the government program, the employers-liability gap filled with a stop-gap endorsement, and the rest of the stack placed in the private market as usual. Keeping that distinction straight is what keeps a contractor from either over-worrying the whole program or under-protecting the comp piece.
What to do before a crew crosses the line
The clean version of this whole topic is three confirmations made before the work starts. First, that the operation is properly registered and in good standing with that state’s fund, because that is the only valid source of comp there. Second, that the employers-liability gap is recognized and filled — typically with a stop-gap endorsement on another policy — since the fund usually does not include it. Third, that the rest of the stack is squared away for work in that state. The work itself differs by trade — a pool service route and a pool construction build carry different exposures into these states — but the three confirmations are the same. When you want your real footprint read against this, including the four monopolistic states, start a quote and tell us where your crews work; we will flag the funds where we cannot place comp and make sure the gap is filled where it matters. And if you operate in one of these states, the local cost guide for that market walks the pricing side with the same honesty.
