A Swedish union has set up a hotline for workers to report instances of “mansplaining” as part of a weeklong effort to raise awareness of a certain kind of condescending elocution that men use to explain to women things they already understand.

Well, actually, it’s not all men who do it, of course, but a certain kind of man. You know him: He is probably getting ready to mansplain this article to you.

The hotline, which is temporary and open to men and women, was set up by Unionen, a trade union that represents about 600,000 private-sector employees in Sweden and describes itself as the largest white-collar union in the world.

“Our objective is to contribute to awareness and start a discussion which we hope will be the first step in changing the way we treat each other and talk about each other in the workplace,” Jennie Zetterström, a union spokeswoman, said in an email on Wednesday.
