Agents and brokers often work more than a standard 40-hour week. They usually work evenings and weekends and are always on call to suit the needs of clients. Although the hours are long and frequently irregular, most agents and brokers have the freedom to determine their own schedule. Consequently, they can arrange their work so that they can have time off when they want it. Business usually is slower during the winter season.
