US dockers push boycott to support Polish workers

A US dockworkers boycott of shipments to and from Poland was imminent thursday and could disrupt grain exports to the troubled East European Communist nation. The International Longshoremen's Association, representing 110,000 dockers along the Eastern Seaboard, announced the boycott Wednesday to show solidarity with striking Polish workers. But union president Thomas Gleason delayed it until international labor unions in Europe were notified.
