The modification and/or removal of marginal functions from a position is an example of a reasonable accommodation. Essential functions are those job duties that an employee must be able to perform, with or without reasonable accommodation.
Factors to consider in determining if a function is essential include:
- whether the reason the position exists is to perform that function,
- the number of other employees available to perform the function or among whom the performance of the function can be distributed, and
- the degree of expertise or skill required to perform the function.
Your judgment as to which functions are essential, and a written job description prepared before advertising or interviewing for a job will be considered by EEOC as evidence of essential functions. Other kinds of evidence that EEOC will consider include:
- the actual work experience of present or past employees in the job,
- the time spent performing a function,
- the consequences of not requiring that an employee perform a function, and
- the terms of a collective bargaining agreement.
