Essential job functions

An essential job function is a set of tasks that comprises the most important activities of a job – they are not job skills, individual job tasks, or job descriptions. ADA regulations list several reasons a function could be considered essential:

1. The position exists to perform the function
2. There are a limited number of other employees available to perform the function, or among whom the function can be distributed, or
3. A function is highly specialized, and the person in the position is hired for special expertise or ability to perform it.
