Most insurance sales agents are based in small offices, from which they contact clients and provide information on the policies they sell. However, much of their time may be spent outside their offices, travelling locally to meet with clients, close sales, or investigate claims. Agents usually determine their own hours of work and often schedule evening and weekend appointments for the convenience of clients. Although most agents work a 40-hour week, some work 60 hours a week or longer. Commercial sales agents, in particular, may meet with clients during business hours and then spend evenings doing paperwork and preparing presentations to prospective clients.
