1952 - First strike of breweries in the Pittsburgh region occurs
All 2,100 of the Pittsburgh area brewery workers went on strike. National breweries took the opportunity to move into the market.
Subsequent strikes in 1955 and 1972 further eroded patronage of regional breweries in favor of national brands. All three of the remaining Pittsburgh breweries, Fort Pitt, Iron City, and Duquesne, were hurt by the strike. Fort Pitt may have been the most damaged and ceased brewing after 1957.
Union negotiated free “beer breaks” continued for brewery workers into the 1980s.
