This photograph appeared on the front page of the New York Tribune in June 1902. It shows a group of striking mineworkers in the Parsons neighborhood of Wilkes-Barre, Pennsylvania.
They posed with a protest sign directed at non-union mineworkers who crossed picket lines to keep collieries open amid the growing 1902 coal strike managed by the United Mine Workers of America (UMWA). The sign states:
“THE SCABS MUST LEAVE TOWN”
Union workers referred to non-union mineworkers as “scabs.”

The 1902 Coal Strike was a massive success for labor organizing in the United States, ushering in an era of gains for organized labor and better pay and working conditions for workers in the Coal Region.
