Manage Food Service Staff. Food and beverage managers are often responsible for recruiting, hiring, training, evaluating and terminating food service staff members. Personnel management of restaurant staff requires experience as well as interpersonal skills.
Work Schedules. Most food service managers work full time. Managers at fine-dining and fast-food restaurants often work long shifts, and some work more than 40 hours per week. Managers of food service facilities or cafeterias in schools, factories, or office buildings usually work traditional business hours.
