Worker’s Memorial Day (April 28) and St. Louis

April 28, 2021 is the 50th anniversary of the opening of the Occupational Safety and Health Administration (OSHA) . The “father” of OSHA was Tony Mazzocchi, then of the Oil Chemical and Atomic Workers Union (OCAW – later merged with the Steel Workers). Mazzocchi helped the local OCAW (the union of the workers at Michigan Chemical) in St. Louis, Michigan confront the worker health issue from the company – especially PBB exposures after the PBB accident. The union calls April 28, Worker’s Memorial Day.
