Most of the people who serve fans at a Chicago Fire match don’t actually work for the soccer club. The concessions are run by a contractor who uses a combination of employees and volunteers to serve guests. The stadium itself is owned and managed by the Village of Bridgeview, the town just outside Chicago where the stadium is located. Trobaugh has only a small internal team of employees to help ensure everyone serving guests is delivering a consistent experience.
Outsourced. The word you should have used is outsourced. It helps keep payroll costs down and liabilty.
