Which jobs are back of house?
Cooks, dishwashers, runners who restock stations, barbacks working the stockroom and setup crew. Hotels often call it heart of house, which means the same thing.
Back of house at catered events
At catered events, back of house is often temporary: a tent kitchen behind a ballroom, or a service corridor turned into a staging area. The staff entrance, break area and load-in route usually sit here too.
