Based in New York, News Media Guild is Local 31222 of The NewsGuild, a sector of the Communication Workers of America.

The national local, previously known as The Wire Service Guild, was formed in 1958, though its roots go back decades earlier in a case that was heard by the U.S. Supreme Court — Associated Press v. Labor Board. In that case, which involved a desk editor, the court ruled that the First Amendment did not shield media companies from labor law.

A majority of NMG members are editorial and technology workers for The Associated Press. Editorial staff at The Guardian-US joined The Guild in 2015, nearly a decade after their counterparts at EFE News Service. With Intelligence (formerly Pageant Media) joined in 2020, Democracy Works and Oxford University Press in 2021, and the Financial Times in 2022.
