California School Groundskeepers Exposed to Roundup: Do You Have a Cancer Claim?

For years, you kept the campus safe and clean. You sprayed weeds along the fence lines, around the playground, near the ball fields, and across the parking lots — often before the students arrived. Roundup was standard equipment, no different than a rake or a hose. Now you’ve been diagnosed with non-Hodgkin’s lymphoma, and you’re wondering if the weed killer you handled year after year had something to do with it.

You’re asking the right question. Thousands of workers have filed lawsuits linking regular Roundup exposure to cancer, and California — with its enormous network of public and private schools — has a workforce that was directly in harm’s way. Yet school groundskeepers, custodians, and maintenance staff are often overlooked in these cases, even though few workers had more consistent contact with the chemical.

The Roundup–Cancer Link: What the Science Shows

Roundup is the most widely used weed killer in the world. Its active ingredient is glyphosate, a chemical sprayed across farms, parks, roadsides, and — for decades — school grounds.

For years, it was marketed as safe. But mounting research has raised serious concerns, especially for people who handled it regularly on the job.

In 2015, the World Health Organization’s International Agency for Research on Cancer (IARC) classified glyphosate as “probably carcinogenic to humans.” That finding pointed specifically to a possible link between glyphosate and non-Hodgkin’s lymphoma (NHL), a cancer that attacks the body’s lymphatic system and white blood cells.

Since then, multiple studies have suggested that heavy, long-term exposure to glyphosate may significantly raise the risk of developing NHL. Researchers focused on the workers with the most contact — the people who mixed, loaded, and sprayed the product week after week.

The core allegation behind these lawsuits is blunt: the companies behind Roundup knew, or should have known, about these risks and failed to warn the workers most exposed to the danger.

Why School Groundskeepers Face Serious Risk

School maintenance workers are a textbook example of occupational exposure — the kind of repeated, high-volume contact these lawsuits center on. Keeping a campus presentable means constant weed control across large outdoor areas, often season after season for many years.

Think about the reality of the job:

Spraying large areas — athletic fields, playgrounds, walkways, fence lines, and parking lots
Mixing and loading concentrate, which means handling the chemical in its strongest form
Working outdoors in all conditions, where mist, drift, and splashes are routine
Years or decades on the same campus, adding up to sustained, long-term exposure

What sets these workers apart is the intensity and duration of their contact. Spraying a home garden a few weekends a year is very different from handling Roundup as part of your daily or weekly duties for years. The more sustained the exposure — through skin absorption, inhaling mist, or accidental contact — the stronger the potential connection to a diagnosis.

Who Qualifies for a California Roundup Lawsuit?

Not everyone exposed to Roundup has a case. Generally, qualifying comes down to two things: a qualifying diagnosis and a documented history of exposure.

You Have a Qualifying Diagnosis

The most common qualifying condition is non-Hodgkin’s lymphoma. Certain subtypes of NHL and some related cancers may also support a claim. A formal medical diagnosis is essential — it’s the foundation of any case.

You Have a History of On-the-Job Exposure

You’ll generally need to show meaningful, work-related exposure. In the school setting, that can include:

School district employees — groundskeepers, custodians, and maintenance workers directly employed by a public or private school district
Contract groundskeepers — landscaping and grounds-maintenance crews hired to service campuses
General maintenance and facilities staff who handled or applied Roundup as part of their duties
Long-term or repeated use — the more sustained your handling of the product, the stronger the connection tends to be

If you’re unsure whether your exposure qualifies, don’t rule yourself out. Employment records, work assignments, and product-use history can often be reconstructed with legal help. A free case review is the fastest way to find out where you stand.

Who Is Being Sued? Bayer and Monsanto

These lawsuits target the companies that manufactured and sold Roundup — not individual schools, districts, or your employer.

Monsanto created and marketed Roundup for decades. In 2018, the German company Bayer acquired Monsanto, and with it, the growing wave of Roundup litigation. Today, Bayer stands as the defendant in these cases.

The central claim is that Monsanto — and now Bayer — knew about the potential cancer risks tied to glyphosate and failed to warn the public and the workers most exposed to it. Plaintiffs allege the companies put profits ahead of safety and never provided adequate warnings that could have protected people on the job.

When a manufacturer puts a dangerous product into the marketplace without proper warnings, it can be held responsible for the harm that follows. That legal principle is what these claims are built on.

What Damages Can You Recover?

When a dangerous product causes serious illness, California law lets you seek compensation for the full scope of your losses — not just your first medical bill. Depending on your situation, recoverable damages may include:

Medical expenses, past and future — chemotherapy, hospitalization, medication, and ongoing treatment
Lost wages for the income you missed during treatment and recovery
Lost earning capacity if your illness limits your ability to work going forward
Pain and suffering for the physical toll of your cancer and its treatment
Emotional distress, including the anxiety, fear, and depression that come with a serious diagnosis
Loss of enjoyment of life when illness takes away the activities and independence you once had

In cases involving especially reckless corporate conduct, additional damages meant to punish that behavior may occasionally apply, though those are never guaranteed. When Roundup exposure contributes to a death, surviving family members may also pursue a wrongful death claim.

The severity of your illness, the strength of your exposure history, and the impact on your life all tend to shape what a claim is worth.

California’s Statute of Limitations and the Discovery Rule

Time is one of the biggest threats to your claim, so pay close attention here. Under California’s statute of limitations, you generally have two years to file a personal injury lawsuit. Miss that window, and you can lose your right to compensation entirely — no matter how strong your case would have been.

But when that clock starts is critical in Roundup cases. Cancer often develops years after exposure, and many workers don’t connect their diagnosis to glyphosate right away. That’s where California’s discovery rule comes in.

Under this rule, your two-year window may not begin until you knew, or reasonably should have known, that you were injured and that Roundup exposure was the likely cause. For many workers, that’s around the time of diagnosis or when a doctor links their illness to chemical exposure.

There’s also a separate deadline to keep in mind: if a loved one has passed away from NHL linked to Roundup, a wrongful death claim generally carries its own two-year deadline running from the date of death.

A Special Rule for Public School District Workers

Here’s a wrinkle that catches many school employees off guard. Your lawsuit for the cancer itself targets Bayer/Monsanto — the product’s maker — and follows the standard rules above. But if any part of your claim involves a public school district or other government entity, an entirely different and much shorter deadline can apply.

The Six-Month Government Claim Rule

Under the California Government Claims Act, if you intend to pursue a public entity, you generally must file a formal written claim with that entity within six months of the date your claim arises. That’s far shorter than the two-year standard, and missing it can wipe out your ability to pursue the public agency at all.

This matters because public school districts are government entities. Whether a claim against a district is appropriate in your situation depends on the specific facts — but the takeaway is simple: if a public school employer could be involved in any way, the clock may be running much faster than you think. An attorney can quickly sort out which deadlines apply to your case so nothing slips away on a technicality.

What to Do If You Suspect Roundup Caused Your Cancer

A few early steps can protect both your health and any future claim:

Keep all medical records, including your diagnosis and treatment history.
Document your exposure — the schools or campuses you worked at, your job duties, years worked, and how often you handled Roundup.
Gather employment records that confirm your work history and product use.
Act on the deadlines — remember the two-year rule and the potential six-month government claim window.
Talk to an attorney early, so evidence is preserved and your claim is handled correctly.

The biggest mistake injured workers make is assuming a diagnosis years after exposure means it’s “too late,” or that a corporation as large as Bayer can’t be held accountable. Neither is true.
