States Lead Heat Protection for Farmworkers While Federal Rule Stalls
Eight states now have occupational heat standards. Federal regulators have proposed protections, but the rule's future remains unclear as farmworkers face deadly summer conditions.
As July heat indexes topped 90 degrees across the farm belt, eight states have moved ahead with occupational heat-protection standards while the federal government’s proposed rule languishes in regulatory limbo. The gap between state action and federal stasis illustrates how farmworkers — uniquely vulnerable to heat stress due to their labor conditions and dress codes — are increasingly left to the protections of their home state.
Washington, Minnesota, California, Oregon, and Colorado already have specific laws governing occupational heat exposure. Illinois is considering legislation that would make it the eighth state to implement requirements for employers related to extreme heat. Yet no federal standard exists, and the regulatory path to one remains blocked.
The scale of risk
Occupational heat-related mortality is 35 times higher among agricultural workers compared to workers from other industries, according to federal data. Dozens of farm and agricultural workers have died from heat stroke since 2015. The hazard compounds for farmworkers specifically: most wear long sleeves and pants year-round to shield themselves from pesticide spray, which simultaneously blocks sweat evaporation — the body’s core cooling mechanism.
The danger is compounded by piece-rate payment structures, which incentivize farmworkers to push through symptoms. A worker paid per bucket of fruit or row of crops can’t afford to take the breaks their body needs to recover from heat stress.
State-level standards fill the void
OSHA convened public hearings on a Biden-era proposal aimed at preventing deaths related to heat illness, but the future of the federal standard is uncertain. In the interim, states have acted. Washington’s heat rule, which took effect in 2008, requires employers to provide shade, water, and rest periods when the outdoor temperature reaches 89 degrees. California’s 2005 heat illness prevention standard sets different triggers by industry and includes mandatory water, shade, and rest.
The state-by-state patchwork creates perverse geography: a farmworker in California benefits from rigorous protections; the same worker across the state line in Nevada or Arizona has no occupational heat standard to appeal to. For migrant workers who follow crops across state lines, protections are inconsistent.
Enforcement and corporate opposition
OSHA continues to conduct heat-related inspections under its National Emphasis Program — Outdoor and Indoor Heat-Related Hazards, launched in 2022, and has cited employers for heat-related violations. But citations require a worker to report a hazard or a fatality to trigger an inspection — a structural vulnerability for workers without stable employment or fear of retaliation.
Agricultural interests have resisted federal heat standards. The Illinois Farm Bureau, which opposes temperature standards for workers, has framed the issue as a “moral obligation” to protect livestock from extreme weather while remaining silent on worker protection.
What a federal standard would require
A federal occupational heat standard would likely establish temperature thresholds triggering mandatory employer action: providing water and electrolyte-replacement beverages, allowing frequent paid rest breaks in shade or air-conditioned space, and monitoring workers for signs of heat illness. It would also require employers to develop heat illness prevention plans and train supervisors.
The cost to employers is modest — shade structures and electrolyte drink are not expensive — but the overhead is measurable. That calculus explains industry resistance.
The political timeline
The Trump administration’s approach to the federal heat rule remains unclear. The proposal was developed under the Biden administration; a new administration typically revisits such rulemakings. For farmworkers, that uncertainty comes during peak heat season — a timing that leaves immediate protection to state-level enforcement and individual workers’ ability to demand compliance from employers.
Until a federal standard exists, state laws remain the only enforceable floor. And for the estimated 2.4 million farmworkers in the United States, most concentrated in states without heat standards, that floor remains dangerously low.
