Is using the phrase”OK boomer” in the workplace inappropriate and a sign of ageism?

The phrase “ok boomer” is an internet meme that young adults use to mock attitudes associated with baby boomers born in the two decades following world war II. There’s a controversy over this phrase in whether it’s offensive to use it in a workplace or not. The point is that many people consider it an age-related insult. Since the older employees are under the protection of a federal statute known as “the age discrimination in employment act,” these terms are considered harassment and discrimination based on age. So, if a colleague or a manager calls the older worker “slow,” “senile,” old fart,” or says something such as “ok boomer,” it is illegal.
