Workers' comp and third-party claims, side by side
This is the single most consequential thing to understand after a serious fall at work, and it is almost never explained by anyone you'll speak to in the first month.

The grand bargain, and its edge
Workers' compensation pays without proving fault, and in exchange you generally cannot sue your employer. That immunity is personal to the employer. Every other company whose negligence contributed — the general contractor, the property owner, an equipment maker, another subcontractor — can still be sued in an ordinary negligence case with no cap.
Workers' compensation was built as a trade. Injured workers get benefits quickly without proving anyone was at fault; employers get immunity from being sued for negligence. That immunity is called the exclusive remedy or comp bar, and for your direct employer it is close to absolute.
The edge of that bargain is where the money is. Immunity is personal to the employer. Every other company whose negligence contributed to your fall — and on a construction site there are usually several — remains exposed to an ordinary lawsuit with ordinary damages.
What each one pays
Comp pays medical treatment, roughly two-thirds of lost wages subject to a state cap, and a scheduled permanent impairment award. It does not pay pain and suffering, loss of enjoyment of life, disfigurement, a spouse's loss of consortium, or the full value of a shortened career.
A third-party claim pays all of it — full lost earning capacity rather than a capped fraction, future medical care, pain and suffering, and the derivative claims of family members. For a catastrophic fall the difference between the two figures is not incremental.
| Workers' comp | Third-party claim | |
|---|---|---|
| Who you claim against | Your employer's carrier | Anyone else on that site |
| Do you prove fault? | No | Yes |
| Medical treatment | Authorised treatment only | Past and future, in full |
| Lost wages | About two-thirds, capped by state | Full lost earning capacity |
| Pain and suffering | Not paid | Paid |
| Disfigurement | Scheduled award only | Paid |
| Spouse's claim | Not available | Loss of consortium available |
| Typical deadline | Notice in ~30 days; claim 1–2 years | State injury deadline, often 2–3 years |
Finding the third parties
The work is identifying everyone who touched that site. It's tedious, and it is where cases are made.
- General contractor — usually holds contractual responsibility for overall site safety
- Property or building owner, particularly on a job they controlled or specified
- Other subcontractors whose crews created or removed a hazard
- Scaffold, lift, and equipment rental companies
- Manufacturers of harnesses, anchors, lanyards, ladders, and lifts
- Architects or engineers, where the design itself made safe work impossible
- Staffing agencies, where the employment relationship is split between two entities
The lien, and why it isn't a reason to skip this
If you recover from a third party, your comp carrier will assert a lien to recoup what it paid out. People hear this and conclude the third-party claim is pointless. It isn't.
Liens are routinely reduced — for the carrier's share of attorney fees and costs, by statutory formula in many states, and by negotiation. A carrier that will otherwise recover nothing has real incentive to compromise. The net to the injured worker after a lien is resolved is regularly a large multiple of the comp benefits alone.
Questions
If I hire a lawyer, do I lose my comp benefits?
No. Benefits are statutory and continue. Retaliating against a worker for filing a comp claim or hiring counsel is itself unlawful in every state.
How do I know whether there even is a third party?
You often can't tell from where you're standing, which is the problem. Contracts, certificates of insurance, site logs, and delivery records identify companies that were never visible to the crew. That investigation is a normal part of a free case review and costs you nothing.
My employer's insurance adjuster has been helpful. Is that a problem?
Not a problem, but understand the scope. The comp adjuster's job is the comp claim. They are not obligated to tell you a third-party claim exists, and it is not in their carrier's interest to develop one. Helpful and complete are different things.
Situations this applies to

I fell off a roof at work
Comp covers part of it. The claim against everyone who isn't your employer covers the rest — and runs on a different deadline.

I fell off a ladder
Who supplied the ladder and who set it up usually decides the case. Preserve the ladder itself.

The roof gave way
Falling through a surface raises different questions than falling off one — mainly who knew it was weak.

A roofer fell at my house
Usually the contractor's insurance answers for it. What determines your exposure is whether they actually had any.
