Because work schedules can be flexible, part-time work is often available, and because people need little or no training to do this work, the food service industry employs a substantial number of people. Additionally, the demand for restaurants and other eateries continues to grow as our population grows. In particular, the large and growing population of senior citizens, who often prefer to dine at restaurants offering table service from waiters, should mean a steady demand for those in this field. According to the U.S. Department of Labor, the overall outlook for those in food service should be about as fast as the average through 2020.
