Workers Compensation in Connecticut: How to File a Claim

Federal law does not mandate a national workers' compensation program. Instead, the Longshore and Harbor Workers' Compensation Act (33 U.S.C. § 901 et seq.) covers maritime employees, and the Federal Employees' Compensation Act (5 U.S.C. § 8101 et seq.) covers federal civilian workers. The Department of Labor oversees these limited federal programs, but most private sector employees fall under state workers' compensation systems.

At the federal level, OSHA (29 U.S.C. § 651 et seq.) establishes workplace safety standards and requires employers to maintain a safe workplace, but OSHA does not provide direct wage replacement or medical benefits for injuries. Instead, OSHA focuses on prevention through inspections and citations.

The Americans with Disabilities Act (42 U.S.C. § 12101 et seq.) and Title VII of the Civil Rights Act (42 U.S.C. § 2000e et seq.) provide separate protections against discrimination based on disability or other protected characteristics, but these are distinct from workers' compensation.

Workers' compensation itself is exclusively a state-level system. Each state, including Connecticut, operates its own program with its own funding mechanisms, benefit levels, and procedural rules. The federal government's role is limited to establishing standards for federal employees and maritime workers.

Connecticut's workers' compensation statute, codified in Connecticut General Statutes § 31-275 et seq., establishes a mandatory, state-administered no-fault insurance system that is significantly broader and more employee-protective than federal baseline protections. Connecticut requires all employers with one or more employees (with very limited exceptions) to carry workers' compensation insurance, regardless of industry or company size. This is stricter than many federal programs, which apply only to specific industries or employee counts.

Under Connecticut law, covered injuries include all work-related injuries and occupational diseases arising out of and in the course of employment (C.G.S. § 31-275). The statute defines compensable injuries broadly and includes both traumatic injuries and cumulative trauma. Connecticut has progressively expanded coverage to include mental health conditions caused by work-related trauma, stress, or violence in certain circumstances, going beyond the traditional physical injury model.

Benefit levels are set by state statute and adjusted annually. The wage replacement benefit is two-thirds of the employee's average weekly wage, subject to a maximum cap that is adjusted yearly. As of 2024, the maximum weekly benefit is approximately $1,074 for temporary disability. Medical benefits are unlimited and cover all reasonable and necessary treatment related to the compensable injury, including surgery, physical therapy, medications, and assistive devices—there is no cap on medical expenses (C.G.S. § 31-294).

Connecticut's coverage is considerably more comprehensive than federal OSHA standards, which focus on workplace safety rather than direct compensation. Unlike the federal Longshore Act, which has time limits on medical benefits and specific occupational disease provisions, Connecticut provides ongoing medical coverage for work-related conditions without arbitrary time restrictions.

The Connecticut Workers' Compensation Commission (now part of the Department of Labor's Workers' Compensation Division) administers claims, investigates disputes, and makes decisions on benefit eligibility. The Commission is a specialized state agency that handles all aspects of workers' compensation administration, from claim filing to appeals (C.G.S. § 31-370 et seq.).

A critical aspect of Connecticut workers' compensation law is the exclusive remedy doctrine: employees cannot sue their employers in civil court for work-related injuries covered by workers' compensation (C.G.S. § 31-290). This provides employers with immunity from lawsuits in exchange for providing no-fault insurance. However, employees retain the right to sue third parties (such as equipment manufacturers or other companies whose negligence caused the injury) outside the workers' compensation system.

Connecticut workers' compensation law contains several important exceptions and limitations that restrict coverage in specific circumstances. Employers with fewer than one employee are not required to carry workers' compensation insurance, though many do voluntarily. However, sole proprietors and partners are generally excluded from coverage unless they elect it, though they can voluntarily participate in the state program.

Employees are excluded from coverage if they are independent contractors rather than true employees. Connecticut applies the ABC test (derived from common law and statutory interpretation) to determine employment status: an individual is presumed an employee unless the hiring entity proves (A) the worker is free from control and direction, (B) the worker performs work outside the usual course of the hiring entity's business, and (C) the worker is customarily engaged in an independently established occupation or business. Misclassification as an independent contractor is a significant issue, and workers who believe they have been wrongly classified can challenge this determination before the Workers' Compensation Commission.

Due-process violations and injuries that do not "arise out of" employment are excluded. For example, injuries sustained during breaks unrelated to work, commuting injuries (unless employer-provided transportation), and injuries caused entirely by the employee's willful misconduct or violation of explicit employer safety instructions may be subject to denial or reduction of benefits. However, Connecticut courts interpret "arising out of" broadly to include risks that are characteristic of the employment, even if not directly caused by job duties.

Occupational disease coverage has been expanded but contains specific procedural requirements. Claims for occupational diseases must be filed within certain timeframes; for example, silicosis and asbestosis claims have special statutes of limitations. Mental health claims arising from work-related causes are now covered in Connecticut, but the injury must result from a documented traumatic event at work or extraordinary and unusual conditions of employment—ordinary job stress does not qualify.

Injuries caused by the employee's sole intoxication or drug use at the time of injury may result in a reduction of benefits or denial. Connecticut courts have held that if substance use is the sole cause of the injury, benefits can be denied, but if the employer failed to provide a safe workplace or adequate warnings, this may not eliminate benefits entirely.

Unauthorized or undocumented employees are generally not excluded from Connecticut workers' compensation coverage; Connecticut law treats all workers as employees for compensation purposes regardless of immigration status, though there are limited exceptions related to federal immigration enforcement.

Employees injured while committing a felony are excluded from coverage. Injuries sustained during strike activity may also be subject to special rules, though generally strikes do not eliminate coverage if the injury was not directly related to strike conduct.

Specific exclusions exist for certain volunteer emergency responders and unpaid interns in strictly limited circumstances, though these exclusions are narrowly construed. Finally, recovery under workers' compensation is the exclusive remedy; an employee cannot sue an employer for a covered injury and cannot receive double recovery from workers' compensation plus a third-party settlement for the same injury.

Step 1 — Document Your Injury and Gather Evidence: Immediately after sustaining a work-related injury, document everything carefully. Photograph any visible injuries, the accident scene, defective equipment, or hazardous conditions that caused the injury. Keep all medical records, prescriptions, test results, and bills—these become critical evidence. Write down the date, time, location, and detailed description of exactly what happened, including any witnesses (with their names and contact information). Preserve any physical evidence (damaged clothing, broken equipment). If you received medical treatment, obtain copies of the initial medical report and physician's assessment of the work-relatedness of your injury. Save all communication with your employer about the injury, including emails and text messages. Document your wages before injury to establish your average weekly wage for benefit calculation purposes.

Step 2 — Notify Your Employer and File an Internal Claim: Connecticut law requires you to notify your employer of your injury within two weeks (C.G.S. § 31-301). Provide written notice to your supervisor, HR department, and your employer's workers' compensation insurance carrier simultaneously—do not rely on verbal notification alone. Include the date of injury, time of injury, exact location, detailed description of how the injury occurred, the body part(s) affected, witnesses present, and any treatment you received. Send this notice via email with read receipt, registered mail, or hand-deliver it and obtain a signed acknowledgment. Your employer is required to have posted Connecticut workers' compensation notices in the workplace informing you of these requirements. Request a copy of the CONN-1 form (Workers' Compensation Form) from your employer, which is the official claim form. Some employers have internal claims processes; follow these but do not rely on them to satisfy statutory requirements. Keep copies of everything you submit.

Step 3 — File Your Official Claim with the Connecticut Workers' Compensation Commission: You must file your formal claim with the Connecticut Department of Labor, Workers' Compensation Division within 30 days of your injury (C.G.S. § 31-301). File online at www.ct.gov/dol/workers-compensation or by mail to: Connecticut Department of Labor, Workers' Compensation Division, 450 Columbus Boulevard, Hartford, CT 06103. Phone the Workers' Compensation Division at (860) 263-6794 if you need assistance or have questions about the filing process. Your claim must include: your full legal name, date of birth, job title, employer name and address, date of injury, description of the injury and how it occurred, body parts affected, date you notified your employer, names of witnesses, your average weekly wage, and any medical treatment received. Attach copies of your medical records, pay stubs (to calculate average weekly wage), and any employer communications about the injury. If you are unable to file yourself due to the severity of your injury, a family member, medical provider, or attorney can file on your behalf. Submit evidence of your notice to employer. The Commission will send you a receipt confirming filing. Keep this receipt and all documentation.

Step 4 — Understand the Investigation and Claim Processing: Once filed, the Connecticut Workers' Compensation Commission begins investigating your claim. The Commission will request additional medical records from your healthcare providers and may require you to undergo an independent medical examination (IME) conducted by a Commission-selected physician. Respond promptly to all Commission requests; failure to cooperate can result in claim denial. Your employer's insurance carrier will also investigate and may accept or deny the claim. If accepted, benefits begin within two weeks. Medical appointments are scheduled by the Commission or carrier; you are required to comply with reasonable medical treatment and attend appointments, or your benefits may be suspended. Keep detailed records of all medical treatment, medications, and medical expenses. Document any time off work due to your injury and inability to perform your job duties. If your employer or their insurer denies your claim, you will receive written notice explaining the denial reason. You have the right to request a hearing before a Workers' Compensation Commissioner to contest the denial. The Commission's decision can be appealed to the Appellate Division of the Workers' Compensation Commission, then to Connecticut Superior Court if necessary. The entire investigation and initial determination typically takes 30–60 days, though complex cases may take longer.

Step 5 — When and How to Consult an Attorney: Consult a workers' compensation attorney as soon as possible after filing your claim, especially if: (1) your injury is serious and will require long-term or ongoing medical care, (2) the employer or insurer initially denies your claim, (3) you are not offered or do not agree with the offered settlement, (4) your employer has terminated you following the injury, (5) benefits are significantly less than you expected, (6) you have a third-party injury claim in addition to workers' compensation, or (7) the injury has prevented you from returning to your previous job. Connecticut allows workers' compensation attorneys to be paid on a contingency fee basis, meaning you pay no upfront costs—the attorney's fee is a percentage of your settlement or award (typically 20–25%), and the Commission must approve all attorney fees. Consult with an attorney experienced specifically in Connecticut workers' compensation law, not general employment law. A qualified attorney can evaluate whether your claim is likely to be approved, negotiate with the insurance carrier for fair benefits, represent you at a Commission hearing if your claim is denied, ensure you receive all medical benefits you are entitled to, and advise you on third-party liability claims. Schedule a free initial consultation to discuss your case. Many Connecticut workers' compensation attorneys offer representation on contingency, meaning you only pay if you win or settle.
