Concession workers at San Francisco's AT&T ballpark staged a protest this week at the stadium to demand better wages and working conditions. Protests, which began in May, continued on Tuesday as the San Francisco Giants took on the San Diego Padres. 

The Bay Area's KRON 4 reports that workers staged a loud but peaceful protest at a garlic fries stand right behind home plate. The workers are striking for a new contract with wage increases, benefits, and job security. The San Francisco Giants have won two championships in recent years and drawn record crowds to the stadium, but workers there have gone 1,541 days without a raise, according to The Giant Zero, a workers' website hosted by Unite HERE.
