You’ve probably heard about the new “OK, boomer” catchphrase that younger people drop when a baby boomer does something that’s condescending, out of touch, or destructive to the future of the planet and society. (So, basically, when boomers do anything?) No surprise boomers AREN’T happy about people being condescending toward them. Could you get fired for saying it at work?
It comes down to the Age Discrimination in Employment Act of 1967. That bans people from creating a hostile work environment over someone’s age and “OK, boomer” qualifies. That rule does not apply both ways. It only applies to people over 40, so older coworkers are free to make millennial jokes with no repercussions.
