Law enforcement remains a growing profession. The demand, especially in big cities, continues to be greater than the supply of qualified people. Future employment, however, may reflect technological and scientific changes taking place in police work. The prospects are best for those with a college background. Police officers usually work forty hours a week.
Most police departments have three shifts.
Police officers are on call twenty-four hours a day. Sundays and holidays can be workdays. Pay may vary with geographic location.
