As this short history of occupational safety and health before and after establishment of the Occupational Safety and Health Administration (OSHA) clearly demonstrates, labor has always recognized perils in the workplace, and as a result, workers' safety and health have played an essential part of the battles for shorter hours, higher wages, and better working conditions. OSHA's history is an intimate part of a long struggle over the rights of working people to a safe and healthy workplace. In the early decades, strikes over working conditions multiplied. The New Deal profoundly increased the role of the federal government in the field of occupational safety and health. In the 1960s, unions helped mobilize hundreds of thousands of workers and their unions to push for federal legislation that ultimately resulted in the passage of the Mine Safety and Health Act of 1969 and the Occupational Safety and Health Act of 1970. From the 1970s onward, industry developed a variety of tactics to undercut OSHA. Industry argued over what constituted good science, shifted the debate from health to economic costs, and challenged all statements considered damaging.
