Certain employers have an unwritten rule that any applicant, who is over 55 years of age, is automatically excluded from consideration for any position whatsoever.

This is an example of age discrimination.

Explanation:

Age discrimination is the term that refers to prejudice and intolerance against a person or a group of people based on their age. This type of prejudice prevents people of a certain age from participating in activities, occupying positions, being selected for jobs, among other situations. An example of this can be seen in the question above, where the company excludes any employee over 55 from any position.
