No experience is needed to work as a postal clerk, but those with prior work experience will increase their chances of landing a job, getting promoted, and possibly earning higher pay.
Because they must memorize many postal regulations, operational rules, and distribution schemes, people in these positions must have a good memory. They must also be able to read rapidly and accurately, as well as possess good hand-eye coordination. Physical stamina is required for both window and distribution clerks and for service agents. Window clerks must stand for many hours at a time, while distribution clerks and service agents must do a great deal of reaching, lifting, walking, bending, and handling packages and heavy sacks of mail. Generally, postal clerks must have the ability to lift and maneuver packages that can weigh up to 50 pounds.
Postal clerks need to have an even temperament and a pleasant disposition. They frequently work under pressure to meet time and schedule deadlines, and their work is often performed with others in close physical spaces. Window clerks must have a neat appearance and a pleasant, congenial manner and must be able to deal with all types of people because they are in constant contact with the public.
