I have worked as a head barista at the Kingdom of Saudi Arabia for two years. As a head barista I made the menu for the restaurant, also I am responsible for calibrating the machines and equipment. I also did the inventories and ordering for the bar station. I also teach other barista in our restaurant.
As a shift supervisor, I am responsible for the productivity and actions of a small group of employees. The supervisor has several manager-like roles, responsibilities, and powers. ... As a member of management, a supervisor's main job is more concerned with orchestrating and controlling work rather than performing it directly.
