United Mine Workers of America (UMW or UMWA) is a North American labor union best known for representing coal miners and coal technicians. Today, the Union also represents health care workers, truck drivers, manufacturing workers and public employees in the United States and Canada. Although its main focus has always been on workers and their rights, the UMWA of today also advocates for better roads, schools, and universal health care.
Michael Stearns was a one-time President of the UMWA in Grantville. After the Ring of Fire, the UMWA became the de facto security force for Grantville in the early days, patrolling the town and its outskirts.
