Occupational Health Must Expand Beyond the Formal Workforce
Occupational health has advanced through better regulation, safer equipment, and stronger prevention programs in many registered workplaces. Yet the field still reaches only a fraction of the people whose labor sustains economies and households worldwide. A commentary in Work argues that health and safety at work can no longer be treated as a problem limited to formal employment in higher-income countries. The real burden stretches into informal labor, forced labor, trafficking, slavery, and child labor, where injury risk and disease exposure are often invisible to mainstream research and policy.
The argument is direct: current occupational health priorities reflect a narrow slice of working life. Formal workplaces in Western countries dominate the evidence base, while millions of workers outside that framework remain undercounted and underprotected. In practical terms, that means prevention strategies, surveillance systems, and return-to-work programs are often designed for people who already have contracts, protections, and some access to care. Those assumptions break down completely in settings where workers are coerced, undocumented, underage, or operating outside any regulatory net.
A narrow research agenda creates a narrow policy response.
Why the Current Evidence Base Misses the Highest-Risk Workers
Occupational health has historically been built around the needs of registered enterprises, factory floors, office settings, and other environments where hazards can be measured and employers can be held accountable. That structure has produced important gains. It has also created a blind spot. When the field centers formal employment, it overlooks workers in informal markets, domestic work, agriculture, extractive labor, construction, migration-linked jobs, and other sectors where exploitation is common and oversight is weak.
The commentary frames this as more than a gap in academic representation. It is a systems problem. If the dominant evidence base comes from workplaces with existing protections, then the resulting guidance will fit those settings best and fail where protections are weakest. The people most likely to suffer musculoskeletal injury, toxic exposures, violence, long hours, heat stress, and psychological trauma are often the least likely to appear in datasets used to shape global occupational policy.
The biological consequences of this omission are not abstract. Unsafe work can drive acute injury, chronic respiratory disease, mental health harm, infectious disease exposure, and long-term disability. In settings of labor exploitation, the risks intensify because workers may not be allowed to stop, report injury, seek care, or leave hazardous conditions. Child labor adds another layer of concern because developing bodies and brains face different thresholds of vulnerability to physical strain, chemicals, and trauma.
Labor Exploitation as an Occupational Health Emergency
The article argues that labor exploitation, slavery, human trafficking, and child labor belong inside occupational health, not beside it. These are not only legal or human rights issues. They are work-related health hazards with direct clinical consequences. A worker forced into unsafe conditions may experience repeated injury, poor nutrition, sleep deprivation, anxiety, depression, and delayed access to treatment. A trafficked person may endure isolation and violence while being kept away from medical care. A child laborer can accumulate injury and developmental harm long before reaching adulthood.
Because these populations are often excluded from official labor statistics, the scale of harm remains difficult to quantify. That absence of measurement should not be mistaken for low prevalence or low severity. The commentary challenges the field to stop treating visibility as a prerequisite for relevance. In many regions, the most dangerous work is precisely the work least likely to appear in formal registries or employer-based surveillance systems.
The clinical implication is straightforward. If the field wants to prevent disease and disability at work, it has to recognize work environments where consent is constrained, wages are withheld, and safety norms are absent. Prevention cannot be limited to improving compliance inside regulated settings. It must also address the conditions in which people are working beyond the reach of standard labor protections.
Reframing Prevention From Workplace Compliance to Global Protection
The call to recommit to health and safety at work globally asks scholars and practitioners to widen the lens. That means studying how injury and illness emerge in informal economies, among migrant workers, and inside systems of coercion and abuse. It also means designing interventions that do not depend on a single employer relationship or on stable access to occupational health services.
Public health surveillance would need to change as well. Traditional occupational datasets may miss whole categories of exposure because they are built around formal employment. A more complete approach would integrate global and public health investigations, human rights data, migration research, and community-based methods. By combining those perspectives, researchers can better estimate who is at risk, where hazards cluster, and how exploitation changes the pattern of disease.
Policy would need the same expansion. Worker protection strategies cannot stop at the factory gate or office door. They must reach farms, private homes, transport systems, construction sites, informal markets, and recruitment chains. They must also address the social and legal conditions that allow trafficking, forced labor, and child labor to persist. Without that shift, occupational medicine will continue to protect the easiest-to-reach workers while leaving the most vulnerable outside the frame.
A Field Defined by Who It Leaves Out
The commentary lands on a hard truth: the current model of occupational health is selective. It has helped many workers, but it still excludes too many of the people most exposed to harm. The result is a field that can describe safety improvements in registered workplaces while remaining underprepared for the realities of global labor.
Bringing exploitation into the center of occupational health would change what gets studied, what gets funded, and what gets prevented. It would also change how clinicians, researchers, and policymakers define a work-related injury or illness. A person forced to labor under threat is still a worker, even if the workplace is hidden from regulation. A child in dangerous labor is still a patient whose health has been shaped by work. A trafficked person injured in transit or confinement is still someone whose condition belongs in the occupational health conversation.
The commentary does not present new trial data or a drug intervention. Its importance lies in the scope of the problem it identifies. Occupational health cannot claim global relevance while focusing mainly on registered workplaces in Western countries. The next phase of the field depends on whether researchers and practitioners are willing to measure harm where it has been easiest to ignore.
