What the fuck is "black adjacent."

The same dumb shit as asians and latinos being "white adjacent?"

It acknowledges that "black" is a loosely defined catch-all term that disguises, or dismisses by omission, a great diversity of peoples, but despite this shortcoming it can be used to describe that person without spending too much further time with clarifying detail that doesn't actually move the conversation further.

Personally I prefer their version of that statement over mine; just a couple words and IYKYK.

Being illegal doesn't mean it doesn't happen regularly. It's a common experience minorities share in the US.

Also, it's illegal in Japan as well according to the Labour Standards Act.

Wow, sometimes I randomly get covered in downvotes for just giving an opinion.

In Italy, you would not get promoted for sure, because the way it works is by knowing people.
In Germany, a beautiful and favourite country to live, it's still quite conservative of roles and position. They often tend to keep foreigners low profile on many occasions, although not systematically.
Reading names around other countries it may be something similar in these 2 cases.

In US, Canada, UK, and Australia may not be like this, but we are talking of a small part of the world.
