With a strong commitment to customer service and the ability to oversee other workers, shift managers are key components to operating successful dining establishments. Fast-food joints, restaurants, bars, casinos, and other places that offer guests items to eat and drink depend on their leadership to create a pleasant, reliable experience. Shift managers generally work full-time—often more than 40 hours per week—and may be called in on short notice when the employer needs extra help. Shifts vary based on when the facility is open and can include early mornings, nights, weekends, and holidays. During busy periods, such as a lunchtime rush, the workplace can be crowded and stressful.
