"In the United States, unions sometimes joined by worker advocacy groups (e.g., Public Citizen and the American Public Health Association) have played a critical role in strengthening worker safety and health protections. They have sought to improve standards that protect workers by participating in the rulemaking process, through written comments and involvement in hearings; lobbying decision-makers; petitioning the Department of Labor; and defending improved standards in court. Their efforts have culminated in more stringent exposure standards, access to information about the presence of potentially hazardous toxic chemicals, and improved access to personal protective equipment—further improving working conditions in the United States."
