If you are injured on a job site that isn’t your employer’s, you may face unique legal circumstances. Workers may mistakenly think that workers’ compensation is their only option for recovery after an accident. In Illinois, construction sites often involve various entities, such as subcontractors and property owners. If one of these parties is negligent and causes your injury, you have the right to pursue an additional claim for damages that workers’ compensation does not cover.

By filing a third-party claim in addition to your workers’ compensation filing, you can maximize the funds available for your medical bills and rehabilitation. For assistance in determining liability and filing a lawsuit, contact Strong Law Offices at 309-393-2928.

    What Does It Mean to Be Injured on a Job Site That Is Not Your Employer’s?

    Getting injured on a job site that isn't your employer's occurs when performing work duties on premises controlled by another company. In industries like construction and logistics, such injuries may lead to a non-employer job site accident claim when a third party fails to maintain a safe environment. In Illinois, the legal framework protects workers from hazards on shared job sites, where actions by one company can easily create risks for others. For example, if a subcontractor leaves debris in a hallway or fails to secure scaffolding, they create an unreasonable risk of harm.

    In Illinois, workers' compensation laws typically prevent you from suing your employer for negligence in exchange for guaranteed benefits. However, this immunity does not cover other parties. If a separate entity caused your injury, you may be able to file a lawsuit against them. A workers' compensation lawyer can evaluate your case to see if a third party's negligence played a role, leading to what is known as a third-party claim.

    Understanding exactly what a third party claim is remains vital for protecting your financial future. It is a civil lawsuit filed against an individual or entity other than your employer. While your workers' comp claim pays for medical treatment and a portion of lost wages, a civil lawsuit can seek compensation for non-economic damages. These include pain and suffering, emotional distress, and the full loss of future earning capacity, none of which are typically available through the workers' compensation system.

    When a Third Party Can Be Held Liable for a Job Site Injury in Illinois

    Liability in these cases usually depends on negligence. To secure compensation from a third party, you must prove that they owed you a duty of care and breached that duty, directly resulting in your injury. A third party liability case often arises in environments where multiple companies operate simultaneously. Control of the worksite and the equipment involved are the primary factors in determining responsibility. Under the Illinois Premises Liability Act, owners or occupants of land have a duty to exercise reasonable care to ensure the safety of people lawfully on the property. If a property owner knows of a dangerous condition, such as a structural weakness or a gas leak, and fails to warn you, they may be held liable for resulting harm. Similarly, general contractors are often responsible for the overall safety of a construction site and can be held accountable if they fail to coordinate safety efforts between various subcontractors.

    Determining the correct defendant is the first step in a third party job site injury in Illinois case. You must look beyond your immediate supervisors to see who else influenced the working conditions. Several specific parties frequently appear as defendants in these types of lawsuits.

    Common third parties who may be liable include:

    • General contractors who fail to enforce safety regulations for the entire site.
    • Property owners who neglect to repair known structural hazards on the premises.
    • Equipment manufacturers responsible for defective tools or heavy machinery.
    • Independent subcontractors whose employees cause accidents injuring other workers.
    • Drivers of vehicles not employed by your company who cause collisions.
    • Maintenance companies contracted to keep a facility safe but fail to do so.

    Negligence is often not obvious at first glance. For instance, a scaffold collapse might seem like a simple accident, but an investigation could reveal that a rental company improperly assembled it, making third party insurance claims against that company appropriate. Similarly, if a delivery driver slips on an icy walkway at a client’s warehouse, the property owner's failure to clear the ice exemplifies premises liability. Identifying these entities allows for recovery that reflects the true cost of your injury.

    How to Pursue a Second Claim Beyond Workers’ Compensation

    Pursuing a non-employer job site accident claim is distinct from a workers' compensation claim, which is an administrative matter, while the former involves civil litigation. To support your claim, it's crucial to gather evidence demonstrating negligence, such as accident reports, witness statements, maintenance logs, and surveillance footage. A construction site injury lawyer can help you establish the sequence of events leading to the accident, focusing on any safety violations or industry standard lapses by the third party.

    To pursue a claim, report the accident to your employer and file for workers' compensation to address medical expenses and lost wages. Then, collaborate with an attorney to identify any non-employer entities, like manufacturers or property owners, that may share responsibility. Meticulous documentation, such as medical records, travel expenses, and communications with insurers, is critical. If a defective product caused your injury, ensure you preserve it in its current state, as it serves as vital evidence of the manufacturer’s liability. Every detail you compile fortifies your case against the third party's failure to provide a safe environment. After gathering sufficient evidence, you can progress to filing a lawsuit against the third party.

    Statistics highlight the prevalence of these dangers. There were approximately 116,600 nonfatal workplace injuries and illnesses in Illinois in 2022, many involving falls, contact with objects, and transportation incidents, which can lead to third-party liability. One advantage of third-party insurance claims is that they can allow you to recover the full value of lost wages, rather than just two-thirds through workers' compensation.

    If you receive a settlement, there could be a workers' compensation lien, meaning the insurance company might expect reimbursement for benefits they've already paid you, for which you then receive compensation from your lawsuit. An attorney can negotiate this lien, which often reduces the amount you owe and allows you to retain more of your settlement.

    Securing your financial recovery after a workplace accident involves looking at every angle of liability. If you were injured on a job site that isn't your employer's, do not assume workers' compensation is the end of the road. You have the right to hold negligent property owners, contractors, and manufacturers accountable for the harm they caused. Contact Strong Law today to schedule a consultation and discuss your claim.
