Fifty years ago today, the Occupational Safety and Health Act (OSHA) went into effect, promising every worker the right to a safe job. The law was won in 1970 because of the tireless efforts of the labor movement and allies, who drew major attention to work-related deaths, disease and injuries, organized for safer working conditions and demanded action from their government. Since then, unions and our allies have fought hard to make that promise a reality—winning protections that have made jobs safer and saved lives. But there is much to be done before the promise to keep all workers safe on the job, during the pandemic and beyond, can be fulfilled.
