The Wing, the members-only association for women that calls itself “a coven not a sorority,” has presented its clubhouses as impeccably designed safe spaces for women to work, network, nosh, primp and talk politics.

Now, a year and a half after first opening in the Flatiron district of Manhattan, the company is also the subject of an investigation by the New York City Commission on Human Rights for possible discrimination violations, said Seth Hoy, a spokesman for the commission.

According to the commission’s website, its purpose is to enforce the New York City Human Rights Law, which “prohibits discrimination in New York City.” The areas covered by the Human Rights Law include employment, housing and public accommodations.

“We are investigating the Wing after receiving a tip from the public and reading media coverage of their policies,” Mr. Hoy said. The news was first reported by Jezebel.
