Job descriptions help the jobholder understand the responsibilities of the position. Job descriptions are helpful to job applicants, employees, supervisors, and human resources professionals at every stage in the employment relationship, from recruitment to retirement. They provide information about the knowledge, training, education, and skills needed for each job. They prevent unnecessary misunderstandings by telling employees what they need to know about their jobs. Best of all, they provide this information in a completely objective and impersonal way.
Job descriptions help management analyze and improve the company's structure.
They reveal whether all company responsibilities are adequately covered and where these responsibilities should be reallocated to achieve a better balance. Accurate job descriptions provide a basis for job evaluation, wage and salary surveys and an equitable wage and salary structure. Finally, they provide a basis from which to determine whether a disabled applicant is otherwise qualified for the job and, if so, to assist in determining what accommodation would be required for the applicant to be able to perform the essential functions of the position.
