Heat Workforce Standards Act of 2025
This bill prohibits the Occupational Safety and Health Administration (OSHA) from finalizing, implementing, or enforcing a safety standard requiring certain employers to create a heat injury and illness prevention plan to evaluate and control heat hazards in their workplaces.
Specifically, OSHA is prohibited from finalizing the proposed rule titled Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings, which was published on August 30, 2024, or any substantially similar standard. The proposed standard generally applies to employers conducting outdoor and indoor work in all general industry, construction, maritime, and agriculture sectors where OSHA has jurisdiction. Employers must develop plans in accordance with the specified standards to address employee exposures to heat indexes at or above 80 degrees (initial heat trigger) or 90 degrees (high heat trigger) Fahrenheit.
As background, the Occupational Safety and Health Act of 1970 generally requires employers to provide their employees with a place of employment that is free from recognized hazards that are causing or likely to cause death or serious harm to employees. OSHA conducts workplace inspections and cites employers that fail to satisfy these requirements. Currently, OSHA does not have specific heat exposure standards; however, OSHA has historically used its general authority to cite employers for violations involving excessive heat, including through a National Emphasis Program that focuses on indoor and outdoor heat exposure in industries that have the highest risks.

Where is it in the process, and what happens next?
The latest action on file does not map to a stage Civibrief recognizes, so the page will not name one. The record's own words are the reliable fact here.

How likely is it to become law?
Civibrief does not forecast outcomes and this page has no opinion about this one. What the record supports is a base rate, which is a fact about the whole pile, not a prediction about this measure.
In the 118th Congress (2023-24), 274 of the 16,565 bills and joint resolutions introduced became law, about 1.7 percent. That count covers every measure at every stage, including the many that never left committee.
This one has no outstanding steps listed above.
Has anyone actually voted on it?
No. No roll call in this Congress cites this measure. That is the ordinary outcome: most measures never reach a recorded floor vote, and a committee ends most of them simply by not acting.
A vote is not the only thing that happens to a measure. Hearings, markups, and referrals are all recorded actions, and none of them is a vote of the full chamber.
Who is behind it?
Mark Messmer (R-IN) introduced it on November 20, 2025, and 68 members have since signed on as cosponsors.
They are 68 Republicans.
Cosponsoring is a formal signature on the text. It is not a commitment to vote for the measure, it does not bind anyone's party, and a long list of cosponsors is a measure of attention rather than of prospects.
How long has it been in play?
It was introduced on November 20, 2025, 294 days ago. The most recent recorded action was 51 days ago, on July 21, 2026.
Measures do not carry over. Anything the 119th Congress has not finished by January 3, 2027 dies when the term ends, and has to be introduced again from the start in the next Congress.
Every answer above is assembled from this measure's own record on Congress.gov and from published counts of what Congress has passed before. Civibrief does not predict outcomes and takes no position on any measure.
