Back Injury at Work: Workers’ Compensation and Third-Party Claims
August 25, 2026 | Article by Chain | Cohn | Clark staff Social Share
A back injury at work is usually covered by workers’ compensation, which pays for medical care and a portion of lost wages regardless of who was at fault. When someone other than the employer caused the injury, however – such as the maker of a defective machine or a negligent contractor – the injured worker may also have a separate third-party claim for damages that workers’ compensation does not cover, including pain and suffering.
Those two claims can proceed at the same time. Which paths are available depends on how the injury happened and who was involved. The sections below explain each path and how they fit together.
What Workers’ Compensation Covers for a Back Injury
Workers’ compensation is a no-fault system. An injured worker only has to prove that their injury arose out of and in the course of employment. In exchange, the benefits are defined and limited: medical treatment for the injury, temporary disability payments for time out of work, permanent disability benefits for lasting impairment, and, in some cases, job retraining.
For most workplace back injuries, this system is also the only claim available against a direct employer. California law treats workers’ compensation as the exclusive remedy against an employer for a work injury, which means an injured worker generally cannot sue their employer in civil court, even in situations where the employer was careless. A few narrow exceptions exist, but they depend on specific facts and are the exception rather than the rule. What workers’ compensation does not include is compensation for pain and suffering, loss of enjoyment of life, or the full value of future lost earnings.
When a Third Party May Also Be Responsible
When a party other than the employer is at fault, an injured worker may bring a civil personal injury claim against that party – known as a third-party claim – in addition to their workers’ compensation case.
Common third parties in a workplace back injury claim include the manufacturer of a defective machine or piece of equipment, a negligent driver in a work-related crash, and a separate contractor or company working on the site. An attorney can assess which parties, if any, may be responsible beyond the employer.
Why the Difference Matters
A third-party claim is a fault-based case, which means it opens the door to damages the workers’ compensation system does not provide. Those can include pain and suffering, loss of enjoyment of life, and the full value of past and future lost earnings, categories that often make up the larger part of what a serious back injury actually costs a person. The two claims can work together. Workers’ compensation continues to pay medical and disability benefits while the third-party case proceeds.
Frequently Asked Questions About Workplace Back Injuries
In most cases, no. California treats workers’ compensation as the exclusive remedy against an employer, so an injured worker generally cannot sue the employer in civil court for a work injury, even if it was caused by the employer’s carelessness. There are a few narrow exceptions, but they depend on specific circumstances. An attorney can tell you whether one applies to you.
A third-party claim is a personal injury lawsuit against someone other than your employer whose negligence caused or contributed to your work injury. It is separate from workers’ compensation and can be pursued simultaneously. Because it is fault-based, it can recover damages that workers’ compensation does not, such as pain and suffering.
No. Workers’ compensation covers medical care, disability benefits, and a portion of lost wages, but it does not pay for pain and suffering or loss of enjoyment of life. Those damages are available only through a civil claim, which usually means a third-party claim against a non-employer at fault.
A workplace injury should be reported to the employer as soon as possible, because California sets a short window for notice, and because a delay can affect benefits. The workers’ compensation claim and any third-party civil claim have separate deadlines. A third-party personal injury claim generally must be filed within two years of the injury. Speaking with an attorney early helps make sure no deadline is missed.
