The ADEA standards apply to age discrimination. The ADEA prohibits requiring people to work in a discriminatorily hostile or abusive environment. … The standards for assessing a hostile work environment claim under the ADEA are analogous to those utilized under [Title VII]. … Thus, the ADEA is violated when the workplace is permeated with discriminatory intimidation, ridicule, and insult … that is sufficiently severe or pervasive to alter the conditions of the victim’s employment and create an abusive working environment.
