Can You Sue Your Employer for a Workplace Injury in Massachusetts?

If you were hurt at work in Massachusetts, one of the first questions people ask is whether they can sue their employer. The short answer for almost everyone is no. The longer answer is more interesting, because Massachusetts law closes one courthouse door and quietly leaves another one open. You generally cannot sue your own employer for a workplace injury, but you can often sue someone else whose negligence caused it, and you can do that while still collecting workers compensation benefits. A lot of injured workers never hear about that second claim, and it is frequently worth far more than the comp claim itself.

The exclusivity rule: why you usually cannot sue your employer

Massachusetts workers compensation is what lawyers call an exclusive remedy system. Under Chapter 152, Section 24 of the General Laws, an employee is treated as having waived the right to sue their employer at common law for a compensable injury unless they gave the employer written notice at the time of hire that they were keeping that right. In practice, essentially nobody files that notice. Most workers have never heard of it, and giving it up is the default that happens automatically when you take the job.

That is the trade at the heart of the comp system. You gave up the right to sue your employer for negligence. In exchange, you get benefits without having to prove your employer did anything wrong at all. Comp is no fault. You can be injured because of your own clumsy moment, or because of nobody's fault, and you are still covered. Our earlier post on what to do after a workplace injury in Massachusetts walks through how those benefits get started, and our guide to how much workers comp pays in Massachusetts covers the wage formula.

The trade has a real cost, though. Workers comp pays a percentage of your lost wages and your medical bills. It does not pay anything for pain and suffering, loss of enjoyment of life, or the full value of your lost earning capacity the way a personal injury lawsuit can. For a serious injury, that gap can be enormous. Which is exactly why the second door matters.

The third party exception under Section 15

Chapter 152, Section 15 preserves your right to bring an ordinary negligence lawsuit against any person other than your employer and its employees who is legally responsible for your injury. The statute is explicit that nothing in the exclusivity provisions bars that kind of action, and it says you are entitled to pursue it without giving up your comp benefits. You do not have to choose between the two. You collect comp now, and you pursue the third party claim alongside it.

Who counts as a third party? On a real Massachusetts job site or workplace, more people than you might think:

• A subcontractor or another company's crew working alongside you, whose employee causes the accident. On construction sites around Boston and Cambridge, where multiple contractors overlap, this is one of the most common third party claims there is.
• The manufacturer of a defective machine, tool, ladder, or piece of safety equipment that failed and hurt you.
• A property owner other than your employer who let a dangerous condition exist where you were sent to work, such as a landlord of a building your employer does not control.
• A driver who hits you while you are driving or walking for work. A delivery driver rear ended on the road has both a comp claim and a claim against the at fault driver.

The comp insurer does get paid back. Section 15 gives the insurer a lien on your third party recovery for the benefits it has paid, and any settlement has to be structured with that reimbursement in mind. That is not a reason to skip the claim. It is a reason to have someone handle the two claims together, because the order of operations and the settlement allocation can change what actually ends up in your pocket.

Rules that shape the third party claim

Two other Massachusetts statutes matter once you step outside the comp system. First, comparative negligence. Under Chapter 231, Section 85, your recovery in a negligence case is reduced by your own percentage of fault, and you recover nothing if you were more than fifty percent at fault. Expect the third party's insurer to push blame onto you for exactly this reason.

Second, the deadline. Personal injury lawsuits in Massachusetts generally must be filed within three years under Chapter 260, Section 2A. That clock runs on the third party claim separately from your comp claim, which moves on its own administrative timeline through the Department of Industrial Accidents. Waiting until the comp side wraps up before looking at the lawsuit is a good way to lose it.

What about suing your employer directly?

The genuinely rare exceptions are worth naming so you know how narrow they are. If you filed that written notice at hire preserving your common law rights, you kept the right to sue, but almost no one has. If your employer illegally carries no workers compensation insurance at all, the law strips the employer of its usual defenses and you may sue directly. And retaliation is its own separate claim: under Chapter 152, Section 75B, an employer cannot fire you or discriminate against you for exercising your comp rights, and that claim goes to court, not the DIA. For the ordinary insured Massachusetts employer, though, the exclusivity rule holds, and the third party claim is where the additional recovery lives.

Get both claims looked at, not just one

The comp system will move along whether or not anyone ever asks who else was at fault. Nobody at the DIA, and certainly nobody at the insurance company, is going to volunteer that a subcontractor or an equipment maker owes you a separate recovery.
