The Glass, Molders, Pottery, Plastics and Allied Workers International Union (GMPIU) approved a merger with the United Steelworkers (USW) at its 75th quadrennial convention. The merger unites the two international unions with complimentary memberships in the United States and Canada.

“The GMP is itself the product of many mergers, and each one made the GMP stronger and better,” says GMPIU International president Bruce R. Smith. “We expect history to repeat itself with the USW merger.”

The GMP, headquartered in Media, Pa., represents approximately 25,000 craft and industrial workers primarily in glass, foundries, molding, plastics and pottery as well as ceramics, china, fiberglass and insulation, and other industries.

“The merger will undoubtedly strengthen and benefit our members in the glass industry and beyond,” says USW International president Leo W. Gerard. “The GMP shares our goals and will be a vital part of the USW.”

The USW represents 850,000 men and women employed in glass, metals, mining, pulp and paper, rubber, chemicals, auto supply and the energy-producing industries, along with workers in public sector and service occupations.
