International Union, United Automobile, Aerospace & Agricultural Implement Workers Of America, Uaw v. Elaine Chao

**What happened:** The United Auto Workers union asked the Occupational Safety and Health Administration (OSHA) to create new safety rules for metalworking fluids - substances used in manufacturing that can be harmful to workers' health. OSHA had an advisory committee that recommended creating these safety standards, but OSHA refused to move forward with making an official rule. The union challenged OSHA's refusal in court, arguing the agency was required to act on the committee's recommendation. **What the court decided:** The Third Circuit Court of Appeals sided with OSHA. The court ruled that OSHA was not legally required to create new safety rules just because an advisory committee recommended them. The judges found that OSHA's decision to reject the rulemaking petition was reasonable and not an abuse of their authority. **Why this matters for workers:** This ruling shows that even when safety experts recommend new workplace protections, federal agencies like OSHA can choose not to implement them. Workers cannot force OSHA to create specific safety rules through the courts, even when advisory committees support stronger protections. This makes it harder for unions and worker advocates to push for new safety standards through legal challenges.
