Whether to use job descriptions usually depends upon a number of factors, including employer preferences and resources. Employers should look at relevant rules and regulations, the size and type of organization and industry, hiring practices, and current employees.
Job functions should be qualified whenever possible and the desired outcome of the work should be described, rather than the method for accomplishing that outcome. For example, instead of saying, “she files folders” write that “the clerk files folders alphabetically based on category." Employers should let individuals read their job descriptions, voice any concerns, and sign their descriptions. Job descriptions should be accurate. To ensure accuracy, combine the input of many managers and employees.
