Workers’ Compensation and Undocumented Workers: What Managers Need to Understand About Their Legal Obligations

8 September 2026

Note for Non-US Readers

The management principles in this article — the duty of care to all workers regardless of status, documentation as the foundation of any claim, and the risks of retaliation — apply universally. This is a paid partnership article. The specific legal framework discussed covers US federal law and the workers’ compensation frameworks of North Carolina and California. UK readers will find the equivalent framework in the Health and Safety at Work Act 1974, the Employers’ Liability (Compulsory Insurance) Act 1969, and employment tribunal case law on worker status. While legal details may differ, the management obligations do not.

Why This Is a Management Issue

In 2025, approximately 31.3 million foreign-born workers were employed in the United States, accounting for around 19% of the civilian workforce. Research groups estimate around 8.5 million undocumented workers participate in the US labour market. These workers are concentrated in agriculture, construction, food processing, hospitality, and cleaning services — sectors where injury rates are among the highest across the economy.

Managers in these sectors — and in any sector where undocumented workers may be employed, knowingly or otherwise — have specific legal obligations that apply regardless of a worker’s immigration status. Understanding those obligations and the consequences of failing to meet them is a management responsibility rather than a legal technicality for counsel to handle. Employees and workers may want to understand whether you can get workers’ compensation if you are undocumented — and in most US states, eligibility is based on the employment relationship and the injury, not immigration status. Good managing performance and workplace wellbeing practice treats the duty of care as applying to every worker on site, not only those whose documentation has been verified.

The Employment Relationship Determines Eligibility — Not Immigration Status

Some employers argue that because hiring an undocumented worker violated the Immigration Reform and Control Act, no valid employment relationship exists — giving them the belief that no workers’ compensation obligation applies. This argument has been rejected by most US states. The reasoning is consistent: permitting an employer to benefit from their own violation of federal employment law defeats the core purpose of workers’ compensation. Avoiding workers’ compensation obligations would undermine the protective purpose of the system entirely.

In practice, this means that the benefits available to an undocumented worker following a workplace injury are broadly similar to those available to any other employee. They must be provided medical treatment connected to the injury and wage replacement during recovery. There is one area of difference: vocational training and placement services may not apply where the worker cannot legally be employed going forward. But the core benefits of medical treatment and wage replacement are generally available.

How This Works in Practice: North Carolina and California

North Carolina’s workers’ compensation framework is no-fault, meaning qualification requires showing the injury occurred at work rather than proving employer wrongdoing. The state requires an injury to be reported to a supervisor within 30 days and a formal claim to be filed within two years. Workers’ compensation lawyers such as Bradley W. Butler at Butler, Quinn & Hochman handle claims under this framework for injured workers across the Charlotte area, including matters where an employer or insurer initially disputes coverage.

California takes a comparably protective stance. State employment law is written broadly enough that most workers who sustain an on-the-job injury are eligible for benefits regardless of documentation status — a position supported by organisations such as Legal Aid at Work. For managers operating across multiple states, the practical implication is to treat workers’ compensation obligations as applying to all workers in all locations, rather than assuming that documentation status creates an exception that doesn’t exist in most jurisdictions.

Documentation and Retaliation: The Management Obligations That Matter Most

The practical factor that most determines whether an undocumented worker can access the benefits they’re legally entitled to is documentation — of the injury, of who was notified, and of what medical treatment was provided. Immigration status is far less determinative than the quality of the injury record. Managers have a direct responsibility for the quality of that record, because it is the organisation’s own incident reporting process that creates or fails to create it. Good leadership and managing change practice builds consistent incident reporting into site operations rather than leaving it to individual discretion at the moment of an injury.

Retaliation protections apply regardless of immigration status. Most state workers’ compensation statutes prohibit employers from terminating, demoting, or disciplining a worker for submitting a claim. Federal workplace safety rules separately protect the right to report an injury. Managers who take adverse action against a worker — documented or not — following a workers’ compensation claim face real legal exposure. The management principle is straightforward: treat every workplace injury the same way, regardless of who was injured or what their status is. The legal obligations are the same — and the consequences of failing to meet them are equally serious regardless of the worker’s documentation status.
