U.S. Sen. Katie Britt joined 15 Republican colleagues Monday in urging the Department of Labor to repeal the Biden-era heat rule, which she argues would burden businesses and potentially endanger the workers it claims to protect.

Britt (R-Montgomery) joined Sen. Bill Cassidy (R-La.) in leading the effort, arguing that the proposed rule’s one-size-fits-all mandates on safety staffing, record-keeping, and mandatory breaks at high-heat thresholds are inefficient and impractical for businesses of varying sizes, locations, and industries.

“Protecting workers from a common and easily understandable workplace hazard does not require a prescriptive rule that will cause confusion and, in several circumstances, may even undermine worker safety,” the senators wrote. “Workers and businesses thrive when there are clear standards that are flexible, understandable, and pragmatic.”

The Biden-era rule would require all businesses to comply with the same heat safety requirements regardless of their safety record, size, or industry.

Critics argue the blanket mandates create dangerous hazards in some workplaces rather than improving safety.

The letter was also signed by Sens. Tommy Tuberville (R-Auburn), Jim Risch (R-Idaho), Thom Tillis (R-N.C.), Cindy Hyde-Smith (R-Miss.), James Lankford (R-Okla.), Ron Johnson (R-Wis.), Eric Schmitt (R-Mo.), Jim Banks (R-Ind.), Mike Crapo (R-Idaho), Joni Ernst (R-Iowa), Ted Budd (R-N.C.), John Cornyn (R-Texas), Tim Sheehy (R-Mont.), and Steve Daines (R-Mont.).

Britt previously introduced the National Right to Work Act, which would protect an individual’s right to form, join, or assist labor organizations, or to refrain from such activities.
