'Please Don't Tell It'
A man mentions to a colleague that he is originally from West Virginia. The colleague laughs and says she knows some "jokes" about people from West Virginia.
She begins to tell one, and it's clear that the "joke" will have an offensive punch line.
The man holds up his hand and says, "Don't tell it. Please don't tell it."
She laughs, perhaps thinking he's joking himself, and tells not one but three "jokes," each with an increasingly bigoted punch line.
The man, at a loss for words, simply sits down when she is done.
Don't laugh. Meet a bigoted "joke" with silence, and maybe a raised eyebrow. Use body language to communicate your distaste for bigoted "humor."
Interrupt the laughter. "Why does everyone think that's funny?" Tell your co-workers why the "joke" offends you, that it feels demeaning and prejudicial. And don't hesitate to interrupt a "joke" with as many additional "no" messages as needed.
Set a 'not in my workspace' rule. Prohibit bigotry in your cubicle, your office or whatever other boundaries define your workspace. Be firm, and get others to join in. Allies can be invaluable in helping to curb bigoted remarks and behavior at the workplace.
Provide alternate humor. Learn and share jokes that don't rely on bias, bigotry or stereotypes as the root of their humor.
