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.
Shift leaders report directly to any assistant manager or managers present. The Bureau of Labor Statistics (BLS) states that in 2010, food servers made a median hourly income of $8.72 per hour, or $18,130 a year. As shift leaders in food service, you can expect to be on the upper end of the average pay.
