Which of these people is responsible for running a kitchen when the executive chef is absent?

A sous-chef de cuisine (French for "under-chef of the kitchen") is a chef who is "the second in command in a kitchen; the person ranking next after the executive chef." Consequently, the sous-chef holds much responsibility in the kitchen, which can eventually lead to promotion to becoming the executive chef. A sous-chef is employed by an institution that uses a commercial-grade kitchen, such as a restaurant, hotel, or cruise ship.

The sous-chef has many responsibilities, because the executive chef has a more overarching role. Sous-chefs must plan and direct how the food is presented on the plate, keep their kitchen staff in order, train new chefs, create the work schedule, and make sure all the food that goes to customers is of the best quality to make customers happy.

Sous-chefs are in charge of making sure all kitchen equipment is in working order. They must thoroughly understand how to use and troubleshoot all appliances and cooking instruments in the event of a malfunctioning cooking device. Sous-chefs are in charge of disciplining any kitchen staff who may have acted against restaurant policy.
