A clerical officer is a person who handles a wide variety of administrative and clerical responsibilities for a particular employer. Specific duties differ for each position, but clerical officers generally support the activities of executive staff.
Obviously, clerical temps need to be proficient in at least basic office skills. They should be able to type, whether on a typewriter or a computer keyboard, and produce documents that are free of typographical, spelling and grammar errors. Although many positions do not require 10-key skills, others do, so 10-key proficiency is desirable.
