However, taxi drivers risk robbery because they work alone and often carry a lot of cash. Full-time taxi drivers usually work one shift a day, which may last from 8 to 12 hours. Part-time drivers may work half a shift each day, or work a full shift once or twice a week. Because most taxi companies offer services 24 hours a day, drivers must be on duty at all times of the day and night. Early morning and late night shifts are not uncommon.
Drivers also work long hours during holidays, weekends, and other special events.
Independent drivers, however, can often set their own hours and schedules. Taxi drivers and chauffeurs meet many different types of people. Patience is required when waiting for passengers or when dealing with rude customers. Many municipalities and taxicab and chauffeur companies require dress codes. In many cities, taxicab drivers are required to wear clothes that are clean and neat.
