Essential functions are fundamental job duties that are necessary to the position.
To identify essential functions of the job, focus on the purpose of the function and the result to be accomplished, rather than the manner in which the function is presently being performed. Employers may not ask job applicants about the existence, nature, or severity of a disability. All questions must be job-related and address essential functions of the job. Statements regarding essential functions are necessary to defend employment decisions and are subject to scrutiny by federal compliance agencies. You, as the hiring supervisor, are accountable for the decisions made in this area.
