Two deadlines control the early life of every workers’ compensation claim in New York. The first is the 30-day deadline to notify your employer of the injury. The second is the two-year deadline to file the C-3 Employee’s Claim Form with the Workers’ Compensation Board. Both deadlines are set by statute. Both carry real consequences if missed. And both are more nuanced than they appear.
This article explains both deadlines in detail — what triggers them, what satisfies them, what happens if you miss them, and how special circumstances like occupational diseases and employer knowledge affect the analysis.
The 30-day employer notification requirement
Under Workers’ Compensation Law Section 18, an injured worker must notify their employer of the injury within 30 days of the accident. The purpose of this requirement is to give the employer timely notice so it can investigate the circumstances, report the claim to its insurance carrier, and arrange for appropriate medical care.
Thirty days is the outside limit. Do not treat it as a target. Report the injury the day it happens. Walk into your supervisor’s office, or call them, or send a text message, and tell them what happened. Then follow up in writing. The sooner you report, the stronger the connection between the injury and your work. Every day of delay gives the insurance carrier one more reason to question whether the injury really happened the way you say it did.
What counts as notice
The law does not require notice in any particular form. Written notice is not required, though it is strongly recommended. Verbal notice to a supervisor, foreman, or manager is legally sufficient. So is a text message, an email, or a written accident report completed at the workplace.
The notice must identify the injury and indicate that it is work-related. You do not need to know the exact medical diagnosis at the time of reporting. Telling your supervisor “I hurt my back lifting boxes in the warehouse this morning” is sufficient notice. You do not need to say “I have a herniated disc at L4-L5.” The specifics will come from your doctor. The notice simply needs to put your employer on alert that a work-related injury occurred.
Notice to a co-worker is generally not sufficient unless that co-worker is in a supervisory role. The notice must reach someone in a position of authority — a supervisor, a manager, a foreman, or a designated safety officer. If you are unsure who to notify, notify your direct supervisor and whoever handles workers’ compensation claims at the company.
What happens if you miss the 30-day deadline
Missing the 30-day notification deadline does not automatically destroy your claim, but it creates a serious obstacle. The Workers’ Compensation Board may excuse late notice if you can demonstrate that: (1) your employer or its insurance carrier was not prejudiced by the delay, meaning the late notice did not prevent the employer from investigating or the carrier from evaluating the claim; (2) you had a reasonable excuse for the delay; or (3) your employer had actual knowledge of the injury through some other means.
The third factor — employer knowledge — is the most common basis for excusing late notice. If your employer witnessed the accident, if you went to the hospital from the job site and your employer knew about it, if your employer arranged for someone to cover your shift because of the injury, or if the circumstances otherwise demonstrate that the employer was aware of the injury, the Board may find that the notice requirement was effectively satisfied even without a formal report.
But do not rely on these exceptions. They are available as a safety net, not as a strategy. The simplest way to protect your claim is to report the injury immediately. Everything that follows becomes harder when the initial notification is late or missing.
The C-3 Employee’s Claim Form
The C-3 is your formal claim for workers’ compensation benefits. It is filed with the Workers’ Compensation Board, not with your employer. Without it, the Board has no record of your claim and cannot process your benefits.
The statutory deadline to file the C-3 is two years from the date of the accident. For occupational diseases, the deadline is two years from the date you knew or should have known that your condition was work-related, or two years from the date of your last exposure to the conditions that caused the disease, whichever is later.
Two years sounds like a long time. It is not. File the C-3 as soon as possible after the injury. Waiting creates problems that compound over time. Witnesses move on. Memories become less precise. Medical records from the initial treatment period become harder to connect to the claim if the C-3 is filed months or years later. Insurance carriers routinely scrutinize the gap between the injury date and the filing date, and they will use that gap to argue that the injury is not as serious as claimed or that the connection to work is weaker than the medical record suggests.
What the C-3 form requires
The C-3 is not a complex document. It asks for your name, address, Social Security number, date of birth, employer’s name and address, the date and time of the injury, the location where the injury occurred, a description of how the injury happened, the part of the body that was injured, and whether you have lost time from work.
Fill out the form completely. Be accurate about the date, time, and location. Be specific about how the injury occurred — “I was carrying a 50-pound box up a stairwell and felt a sharp pain in my lower back on the third step” is better than “I hurt my back at work.” The more specific the description, the harder it is for anyone to dispute the claim later.
If you are unsure about any detail — the exact time, the precise sequence of events — provide your best recollection and note that the detail is approximate. It is better to file a C-3 with approximate information than to delay filing while trying to confirm every detail. You can supplement or correct the information later.
The form is available online at www.wcb.ny.gov and can be filed electronically or by mail. If you file by mail, keep a copy and send it by certified mail so you have proof of the filing date.
How the C-3 relates to your employer’s C-2
Your employer is required to file a separate form — the C-2 Employer’s Report of Work-Related Injury/Illness — with the Board and with its insurance carrier within 10 days of learning about the injury. The C-2 is the employer’s report. The C-3 is your claim. They are independent of each other.
Do not assume that your employer’s filing of the C-2 eliminates your need to file the C-3. It does not. Some injured workers believe that once they report the injury to their employer, the employer handles everything. That is not how the system works. Your employer files the C-2. You file the C-3. Both must be filed. If your employer does not file the C-2, that is a problem for the employer, but it does not affect your ability to pursue your claim as long as you have filed your C-3.
Special timing rules for occupational diseases
Occupational diseases and repetitive stress injuries present timing challenges that sudden accidents do not. A worker who slips on a wet floor knows exactly when the injury occurred. A worker who develops carpal tunnel syndrome after years of repetitive motion may not be able to identify a single date.
For occupational diseases, the 30-day employer notification clock begins when you first become aware — or reasonably should have become aware — that your condition is related to your work. In practice, this often means the date your doctor first tells you that your condition may be work-related. As soon as you receive that information, notify your employer. Do not wait for a definitive diagnosis. Notify on the possibility.
The two-year C-3 filing deadline for occupational diseases can also be calculated differently. It may run from the date of disablement (the date you first became unable to work due to the condition) or from the date of your last exposure to the workplace conditions that caused the disease. Because these dates are often uncertain and subject to dispute, file the C-3 as early as possible. Let the Board sort out the exact calculation. Your job is to get the form filed.
How Schwartzapfel Holbrook addresses notification and filing issues
At Schwartzapfel Holbrook, we review the notification and filing timeline in every workers’ compensation case. When a client comes to us with a late notification or a delayed C-3 filing, we evaluate the circumstances to determine whether the Board is likely to excuse the delay — including whether the employer had actual knowledge of the injury, whether the delay caused prejudice, and whether there was a reasonable excuse.
For occupational disease cases where the timing of notice and filing is inherently complex, we work to establish the date of awareness and the date of last exposure through the medical record and the employment history. These are factual determinations that require careful documentation. Getting them right at the outset prevents problems at a hearing.
