A job description is an internal document that a firm draws up to describe the responsiblities of a position, the required skill, and job requirements to perform a particular job role.
When a job description is well crafted it shows clearly what is required to hire a person for a job. This will reduce discrimination lawsuits because it will show clearly why a particular candidate was disqualified from the hiring process.
For example if a candidate was disqualified for not having a bachelor's degree, it should be well stated in the job description to avoid discrimination claims.
