Being hurt at work by someone who does not work for your employer leaves you inside a system that was not built for it. Zavodnick & Lasky Personal Injury Lawyers handle third-party work injury claims in Pennsylvania, alongside the workers’ compensation claim, for people injured in Philadelphia.
Workers’ compensation pays medical treatment and part of your wages, and it pays nothing for what the injury actually did to your life. That gap is not an oversight. It is the trade Pennsylvania made when it barred workers from suing their own employers, and it is why the second claim matters so much when someone outside your company caused the injury.
That is the gap a third-party work injury claim fills. Call (215) 875-7030.
What is a third-party work injury claim?
It is an ordinary injury lawsuit against someone other than your employer whose negligence caused a workplace injury. It runs alongside the comp claim rather than replacing it, and it reaches damages the comp system does not pay.
The two claims answer different questions. Workers’ compensation asks whether you were hurt at work. A third-party claim asks who was at fault, which is why it takes longer, requires proof of negligence and pays considerably more when the proof is there.
| Workers’ compensation | Third-party claim | |
| Who it runs against | Your employer’s insurer | The outside company or person at fault |
| Fault | Not required | Must be proven |
| Wage loss | About two-thirds, up to a weekly cap | Full past and future loss |
| Pain, limitation, loss of enjoyment | Not covered | Covered |
| Spouse’s claim | Not available | Available in many cases |
Who counts as a third party on a Philadelphia job site?

Anyone outside the employment relationship whose conduct contributed to the injury. On a construction site, that regularly means a general contractor or another trade working the same site, since a worker employed by the electrical subcontractor is not employed by the framing crew that left the opening in the deck.
The list runs further. The driver who hit a worker making deliveries. The property owner who let a loading dock or stairwell deteriorate. The manufacturer of a machine whose guard was defective or whose safety interlock was easy to defeat. The company that serviced the equipment.
Staffing agency placements are their own analysis, because a worker placed by an agency may have two potential employers, and that answer decides who can be sued and who is protected.
If you are unsure whether anyone outside your company was involved, that question is worth twenty minutes on the phone. Call (215) 875-7030.
What the employer’s lien means for your recovery

This is the part injured workers learn about late, and it changes how a case should be handled from the beginning. Under Section 319 of the Pennsylvania Workers’ Compensation Act, the employer or its insurer is entitled to be repaid out of a third-party recovery for the benefits it paid.
Pennsylvania courts treat that right as statutory and absolute, so the goal is not to dodge the lien but to handle it correctly. The costs of obtaining the recovery, including counsel fees, are apportioned, which means the comp carrier bears a share of the expense of the case that produced its reimbursement.
Anything left after the lien is satisfied usually gives the employer a credit against future compensation, calculated as a percentage and reported to the state on a third-party settlement agreement. A settlement structured without that math in view can leave a worker with a check that looks large and a comp claim that has quietly stopped paying.
One question worth raising early with any lawyer you consult: how the lien is expected to apply to each source of recovery in your case, including any claim under your own auto coverage.
How the two claims get handled together

Timing matters. The comp claim opens immediately, because it pays the treatment. The third-party case takes longer to develop, needs evidence that disappears, and should not be settled before the medical picture is clear.
Evidence on the third-party side goes first: photographs of the equipment or the condition, the site safety plan and daily reports on a construction project, the contracts between the companies on site, any OSHA inspection documents, and the machine itself, which should be preserved rather than repaired.
Then the coordination. A comp settlement signed without accounting for the pending injury case, or an injury settlement signed without resolving the lien, can cost more than either claim was worth separately. Handling both under one roof is the practical reason these cases go to firms that do both.
Questions Philadelphia workers ask about suing outside the employer
Can I sue my employer if the injury was clearly their fault?
Generally no. Pennsylvania’s comp system is the exclusive remedy against an employer for a work injury, with narrow exceptions. That bar does not extend to other companies, which is exactly where the third-party claim lives.
Will filing a lawsuit put my workers’ comp benefits at risk?
No. The comp claim continues on its own track, and the employer’s interest in the lawsuit is reimbursement rather than opposition. Retaliation for pursuing an injury claim is its own legal problem for an employer.
A subcontractor on the site hurt me, but we all worked for the same general contractor. Can I still sue?
Sometimes. The answer turns on the contracts and the structure of the project, because some arrangements make a general contractor a statutory employer and immune from suit. That is a document question, and the documents exist.
What if the machine that injured me was defective?
That is a product liability claim against the manufacturer, and it is one of the most common third-party cases we see. Preserving the machine, its guards and its maintenance history is urgent, since employers routinely repair or replace equipment within days.
Ask whether there is a second claim before the evidence goes

Most injured workers file the comp claim and never learn that they can collect workers’ comp and a personal injury settlement when someone else was responsible. The answer is usually in photographs, contracts and equipment that exist in week one and not in month six.
