In an effort to get a new contract, hundreds of workers at Wrigley Field could walk off the job this weekend. The members of UNITE HERE Local 1, voted by an overwhelming majority to authorize a strike. More than 700 union members work as bartenders, cashiers, cooks, dishwashers, suite runners and warehouse workers at Wrigley Field. They are seeking a $20 per hour minimum wage, expanded health care coverage and a pension.
