Your duties as a deli manager depend on the location of your employment. In every deli, your responsibilities include overseeing operations, inspecting food quality and display case presentation, and managing food safety practices and cleaning. You also manage other deli employees, perform on-the-job training, and ensure quality customer service. In a meat department at a grocery store or market, you may be in charge of inventory and food costs. At a restaurant, you may help deli clerks with food preparation, engage with customers during ordering, or aid the cashier during peak hours.
